How Has Technology Changed Art?

We all are witnessing the changes being made in the art these days. Technology has the power to change anything. It is changing the traditional art into digital art.

Amazing digital art has taken place of traditional art. Digital art is exploring itself in many different ways that one can imagine. Different software is developed to increase the presence of digital art.

Photoshop Artists are one of the most common digital artists who give an amazing look to a picture with the help of imaging software and different applications.

These applications are developed with the help of technology. Anyone can be a digital artist having knowledge and proficiency in Photoshop.

Difference between traditional artists and digital artists is that traditional artists use paint and cement for their art and digital artists use imaging software and applications in their art. Some of the applications have the power to create 3D art work.

Technology has taken art into a new level of creativity. Let us talk about how technology has changed traditional art into digital art. We know that internet is ruling the world with its power. So, artists decided to present their art online with the help of internet. This is possible with use of technology.

You must have seen art galleries and attended painting exhibitions in your life. These doesn’t work well these days so artists find a way where they can get more attention and more praise for their work. Most of the artistic stuff is now seen online and is circulated to the art lovers.

There are some places where exhibitions are held and we do respect them. But presenting paintings, sculptures and art work online is in trend. Some of the artists are also showing their art on the basis of card swipe panel or coins.

How this work – when you enter coins or swipe card in the panel, the panel shows you some of the art work for a few minutes and then gets closed and if you want to see it again or explore more, further you need to swipe your card or add coins into it. This is how artists are using technology.

How digital artists are using technology for their art work

Digital artists already in touch with technology are aware of the systems that are in trend and use them to create their art work and sell them online.

Some of the professional digital artists are earning a lot of bucks by selling their art work. They can also design the ones that you want and are also ready to make any modifications you need.

They use different software to explore their skills and made it more impressive. They are using technologies that offer new ways to express their art work in a realistic way for much more time.

They are using different types of media and mix them to provide a more creative art work. Their 3D art work looks as real as it is present live in front of you.

Technology not only brings changes in education, medical field, industry and business but also brings a huge change in the art work and the artists as well.

Technology opens different paths for the artists to enter into for a good earning. They made their profession more powerful along with their art work.

In our busy lives we hardly get time to meet each other and our loved ones. How can it be possible to see exhibitions and galleries? So technology has brought this change in the art workers to show their skills and talent to people from anywhere in the world.

Technology is getting advanced and making more useful for the common man as well as artists. Technology has provided us with several things that we should be thankful. One of them is digital art work.

The Importance Of Excel In The Workplace

Excel is perhaps the most important computer software program used in the workplace today. That’s why so many workers and prospective employees are required to learn Excel in order to enter or remain in the workplace.

From the viewpoint of the employer, particularly those in the field of information systems, the use of Excel as an end-user computing tool is essential. Not only are many business professionals using Excel to perform everyday functional tasks in the workplace, an increasing number of employers rely on Excel for decision support.

In general, Excel dominates the spreadsheet product industry with a market share estimated at 90 percent. Excel 2007 has the capacity for spreadsheets of up to a million rows by 16,000 columns, enabling the user to import and work with massive amounts of data and achieve faster calculation performance than ever before.

Outside the workplace, Excel is in broad use for everyday problem solving.

Let’s say you have a home office. You can use Excel to calculate sales tax on a purchase, calculate the cost of a trip by car, create a temperature converter, calculate the price of pizza per square inch and do analysis of inputted data. You can track your debt, income and assets, determine your debt to income ratio, calculate your net worth, and use this information to prepare for the process of applying for a mortgage on a new house. The personal uses for Excel are almost as endless as the business uses for this software – and an Excel tutorial delves into the practical uses of the program for personal and business use.

The use of spreadsheets on computers is not new. Spreadsheets, in electronic form, have been in existence since before the introduction of the personal computer. Forerunners to Excel and Lotus 1-2-3 were packages such as VisiCalc, developed and modeled on the accountant’s financial ledger. Since 1987, spreadsheet programs have been impacting the business world. Along the way, computerized spreadsheets have become a pervasive and increasingly effective tool for comparative data analysis throughout the world.

Today, end users employ Excel to create and modify spreadsheets as well as to author web pages with links and complex formatting specifications. They create macros and scripts. While some of these programs are small, one-shot calculations, many are much more critical and affect significant financial decisions and business transactions.

Widely used by businesses, service agencies, volunteer groups, private sector organizations, scientists, students, educators, trainers, researchers, journalists, accountants and others, Microsoft Excel has become a staple of end users and business professionals.

The beauty of Excel is that it can be used as a receiver of workplace or business data, or as a calculator, a decision support tool, a data converter or even a display spreadsheet for information interpretation. Excel can create a chart or graph, operate in conjunction with Mail Merge functions, import data from the Internet, create a concept map and sequentially rank information by importance.

Excel offers new data analysis and visualization tools that assist in analyzing information, spotting trends and accessing information more easily than in the past. Using conditional formatting with rich data display schemes, you can evaluate and illustrate important trends and highlight exceptions with colored gradients, data bars and icons.

Indeed, Excel can be customized to perform such a wide variety of functions that many businesses can’t operate without it. Excel training has become mandatory in many workplaces; in fact, computer software training is a must for any workplace trying to keep up with the times.

Let’s say you’re an employer with 97 workers, 17 of whom called in sick today, and you want to know the percentage represented by absentees. Excel can do that. You can learn Excel and use it to determine the ratio of male to female employees, the percentage of minorities on the payroll, and the ranking of each worker by compensation package amount, including the percentages of that package according to pay and benefits. You can use Excel to keep track of production by department, information that may assist you in future development plans. You can create additional spreadsheets to track data on vendors and customers while maintaining an ongoing inventory of product stock.

Let’s say you want to know your business production versus cost. You don’t have to be a math wiz – you just have to learn Excel. Excel allows you to input all of the data, analyze it, sort it according to your customized format, and display the results with color, shading, backgrounds, icons and other gimmicks that offer time-saving assistance in later locating precisely the information desired. If this spreadsheet is for presentation purposes, Excel helps you put it together in such a visually appealing way that the data may seem to pop and sparkle.

The single most important thing an employer may do is learn Excel – it is one of the most essential tools of the workplace.

Excel and Microsoft are trademarks of Microsoft Corporation, registered in the U.S. and other countries. Lotus is a registered trademark of International Business Machines Corporation in the U.S. and/or other countries.

Introduction to Silk Test Architecture

Normal use of an application consists of a person manipulating a keyboard and mouse to initiate application operations. The person is said to be interacting with the GUI (Graphical User Interface). During Silk Test testing, Silk Test interacts with the GUI to submit operations to the application automatically.

Thus Silk Test can simulate the actions of a person who is exercising all the capabilities of an application and verifying the results of each operation. The simulated user (Silk test) is said to be driving the application. The application under test reacts to the simulated user exactly as it would react to a human rest. Silk Test consists of two distinct software components that execute in separate processes:

The Silk Test host software

The 4Test Agent software

Silk Test host software

The Silk Test host software is the program you use to develop, edit, compile, run and debug your 4Test scripts and test plans. This manual refers to the system that runs this program as the host machine or the Silk Test machine.

The Agent

The 4Test Agent is the software process that translates the commands in your 4Test scripts into GUI-specific commands. In order words, it is the Agent that actually drives and monitors the application you are testing. One Agent can run locally on the host machine. In a networked environment, any number of Agents can run on remote machines. This manual refers to the systems that run remote Agents as target machines. This manual refers to the systems that run remote Agents as target machines. In a client/server environment, Silk Test drives the client application by means of an Agent process running on each application’s machine. The application then drives the server just as it always does. Silk Test is also capable of driving the GUI belonging to a server or of directly driving a server database by running scripts that submit SQL statements to the database. These methods o directly manipulating the server application are intended to support testing in which the client application drives the server.

Texas Two Step Strategy – Everything You Need to Know

The Texas Two Step lottery is a great example of a game that is both strategic and fun. The state lottery is an excellent arena for you to shell out your extra dollars while learning about alternative lotto mechanics. In the state of Texas, the Texas Two Step is considered to be the most popular form of lottery. The game beings when an individual is asked to pick four number from and in between 1 to 35. Like most lotto types, this also has a bonus ball number, which can increase your chances of winning. The grand price for this unique game does not go below two hundred thousand dollars so long as you make five matches. If you are also quite hesitant to pick your own number, the quick pick system also applies to the Texas Two Step lottery. A multi-draw feature also allows you to bet for ten advance drawings at once by simply making a distinguishable mark in the designated ticket boxes. Single plays cost only US$1 each and can reflect winnings up to a hundred thousand dollars.

Most lottery systems base on luck as foundation for winning. Unfortunately, even with the convenience of quick picks and other strategies, chances of winning are still small. One effective way to increase the chances of gaining back positive results from your chosen number is by adhering to the Wheeling Systems. Generally, wheeling systems do not guarantee an automatic win after placing your number picks in the Texas Two Step. However, the mechanism gives you more chances of bringing home multiple tier prizes as opposed to you simply randomly selecting the number, or relying on quick picks. The odds of winning the Texas Two Step prize are statistically ranging from 1 to 32. The overall ratio of victory can be quite unsatisfactory if played with mere dependence on luck. Although you can win $5 for simply matching the bonus ball number, naturally, anyone would still want to vie for the grand prize.

There are also a handful of lotto software that provide good combination numbers for players. Most people confirm the effectiveness of most online programs in tracking the best numeral combinations for lottery. You may program these to suit your needs and according to the type of lottery that you participate in. For Texas Two Step, it is much easier to use a software to calculate possible combinations as it has lesser selections or numbers compared to most lotto games.

For serious lotto players, individuals simply log onto the website and place their bets randomly. Sites also offer a few tips and strategies on how to best employ their gaming techniques. You may be able to view advices on when is the best time to place your bets and how to purchase your tickets quickly. Other websites also present lottery news, which is also an effective way to keep track of your bets. Bear in mind that in order for a player to achieve positive results while playing lotto, the correct strategy and technique must put in place so as to lead you to triumph and victory.

Understanding the Significance of Computer Hardware

We are living in an age that is highly influenced by technology. Most of the activities we need to do now are automatic or computerized. Of all the technological developments achieved in the recent past, one significant tool that got developed and which will certainly keep influencing our lives is the computer. You would agree that computers play a very basic role in our daily life, just like the television and the cell phone. We are already at a stage where life will be difficult without a computer. That makes it important to understand the way a computer works, and then be informed of what we should do if it stops working. The most important part of any computer is its hardware, in the absence of which it just can not function.

If you are really keen to assess what has gone wrong with your computer when it stops working, you should understand the working and constituents of its hardware. You should especially have solid knowledge about the computer hardware when you want to undertake its troubleshooting on your own. One important part of the hardware is the RAM memory of any computer. For running any program or application, any computer needs a RAM memory. Other than that, if the computer has a RAM with specifications that are not compatible with the programs it is expected to run, its operation will be slowed down and it would almost crawl. When choosing a computer, you need to ensure that its hardware is not outdated, otherwise you'll have to upgrade it in order to be able to use the intended program.

You must take certain basic precautions while handling the hardware of computers. The most essential precaution is to ensure that the power supply to your computer is switched off, else it could cause an electric shock. Then, before you touch any part within the computer, ensure that you are not carrying any electric charge by connecting to a grounded piece of metal or you may procure an anti-static mat or wrist band available in the market. While inspecting the hardware components, you should look for broken or damaged component, as these are most likely the reasons for the computer malfunction. If a component does not fit in the slot, you are probably trying to fit it in the incorrect slot.

Once you know the hardware employed in your computer and the role it plays in the functionality of your computer, you'll be in a position to undertake its troubleshooting when it malfunctions. Each piece of hardware contributes to the successful function of the computer. To a large extent, the working of a computer depends on the quality of its hardware, making it imperative to keep it in good condition.

What is the Purpose of ERP Software?

Enterprise Resource Planning (ERP) software can be described as a complete business software solution. It is aimed at the integration of all business processes and sub-processes into a single unified system. This system is formulated and implemented in an organization to effectively and efficiently achieve the business goals of the organization.

ERP packages are implemented to manage the existing and prospective business plans and policies in an efficient manner under strict deadlines. It can be referred to as the ultimate business solution package that is predominantly concerned with making sure that the available resources of the organization are utilized in the best possible manner and coordinated with the business objectives of the organization.

It is crucial that modern day business organizations have a single unified system, which aims at harmonizing its business efforts. This can prove to be a crucial determinant in deciding the scope, area and net results of the organization as a whole, rather than running many different systems that don’t work well together. What makes ERP different from any other business solution package is the presence of a single and unified database system.

ERP software is as essential to the needs of a business today as food is for living. Businesses cannot run competitively in the absence of properly drafted and formulated ERP software. The more effective implementation and follow-up, the better are the results. ERP software is needed by all modern-day organizations, irrespective of the size, area of operations and business objectives.

Nowadays there are many ERP packages available in the global market, including SAP, PeopleSoft, Oracle, J D Edwards, and BAAN.

The selection of an ERP software package is dependent on many factors: previous software implementation, nature and size of operations, recommendations of consultants, and management decisions.

Before installing specialized software, a detailed study must be made and reviewed to match the business requirements with the available packages. This must be taken as a serious study as any mistake in selection or its effective implementation can prove disastrous to the organizational objectives and prospects. The ERP software must be installed by an ERP vendor or third-party consulting organization, which are expert service providers when it comes to providing Consulting, customization and support.

Some of the benefits of ERP Software:

* All processes and sub-processes are linked and unified into a single system.

* There are enhancements in the field of productivity, efficiency and achievement of business objectives.

* ERP tends to considerably reduce the response time by effectively transferring crucial information.

* ERP helps in streamlining the numerous functions performed by the organization as a whole.

* It helps the management to make vital decisions with unparalleled accuracy and in-depth study.

Thus, ERP software can effectively change the outlook of any business organization that exists in today’s cutthroat business world. Proper implementation of the ERP software is the key factor, which can benefit the growth prospects of any organization.

What Is The Difference Between ERP And Enterprise System?

Enterprise system and Enterprise Resource Planning System terms are similar but there is difference between an enterprise system and an ERP system. An ES or enterprise system is a large scale system which includes packages like ERP and CRM. ERP is a subset of Enterprise System or it can be said that ES is a superset of ERP. It contains a variety of solutions. ES contains applications and packaged solutions which can be directly used in an enterprise. On the other hand ERP system is the automation of the business processes and the solutions are in the form of modules which are designed according to the client’s requirements.

The functions are customized according to the client’s business environment. Enterprise system does not include architecture of other solutions whereas an ERP implementation automates systems using technical aspects. ERP system includes architectures and databases and is client server architecture. The system is server based therefore the consultant needs to be aware of the technical aspect too.

Another difference between an ES and an ERP system is that the ERP is aimed at improving the functionalities of the organization whereas the ES helps to improve the overall maintenance and accuracy. It provides for better solutions and aids in decision making. ES is difficult to implement compared to Enterprise resource planning and even the timeframe needed for implementation maybe more. The overall impact is high but so are the risks involved. If the ES is not implemented in the right manner, it can cause business failure and if implemented properly it can increase the efficiency and profits of the business organization. It is normally required when there is a big drawback in the current procedures and methodologies in the organization and need to be corrected. The company going in for enterprise system needs to be careful while choosing the software and the vendors due to the risk of failure involved.

The difference between an enterprise system and an ERP system is that ERP is mostly used for medium scale companies to big companies and ES is restricted to the big companies. There are many complex functions involved in big companies which cannot be provided solutions for alone by ERP. The role of ERP is restricted when compared to enterprise system because it does not include customer relationship or vendor management.

These applications are needed when the business process is complex and on a big scale. Therefore bigger organizations need to go with ES instead of enterprise resource planning alone. ERP is also an important system to streamline the internal processes but it does not provide for taking care of the external processes. Enterprise system takes care of the end to end business process of organization since it involves other applications also like SCM and CRM. There is quite a lot of difference between an enterprise system and an ERP and it depends on the company whether it wants to go with an ES to streamline the entire process starting from supplying, production and customer or whether he wants to go with an ERP system to streamline the internal process.

Wide Area Network (WAN)

Types and Characteristics of WANs

What is a WAN?

There are two prevailing definitions of a Wide Area Network (WAN). The book definition of a WAN is a network that spans large geographical locations, typically to interconnect multiple Local Area Networks (LANs). The practical definition of a WAN is a network that traverses a public network or commercial carrier, using one of several WAN technologies

What are its Main Components?

The main components for a WAN are routers, switches and modems. These components are described below in the hardware section.

CPE – Devices on the subscriber contracts are called customer premises equipment (CPE).
The subscriber owns the CPE or leases the CPE from the service provider. A copper or fiber cable connects the CPE to the service provider's nearest exchange or central office. This cabling is often called the local loop, or "last-mile".

DTE / DCE – Devices that put data on the local loop are called data circuit-terminating equipment, or data communications equipment (DCE). The customer devices that pass the data to the DCE are called data terminal equipment (DTE). The DCE primarily provides an interface for the DTE into the communication link on the WAN cloud.

Hardware

In a WAN you will need various types of hardware components for it to function. The typical items of hardware that you will need in a WAN are:

Router – An electronic device that connects a local area network (LAN) to a wide area network (WAN) and handles the task of routing messages between the two networks. Operates at layer 3, and makes decisions using IP addresses.

Switch – A switch is a network device that selects a path or circuit for sending a unit of data to its next destination. Operates at layer 2, and uses MAC addresses to send data to correct destination.

Modem – Short for modulator / demodulator, a modem that enables a computer to communicate with other computers over telephone lines. Operates at layer 1, where signals are converted from digital to analogue and vice versa for transmission and receiving.

Wan Standards

WANs operate within the OSI model using layer 1 and layer 2 levels. The data link layer and the physical layer. The physical layer protocols describe how to provide electrical, mechanical and functional connections to the services provided by the ISP. The data link layer defines how data is encapsulated for transmission to remote sites.

Encapsulation

Encapsulation is the wrapping of data in a particular protocol header. Remember that WANs operate at the physical layer and the data link layer of the osi model and that higher layer protocols such as IP are encapsulated when sent across the WAN link. Serial interfaces support a wide range of WAN encapsulation types, which must be manually specified. These types include SDLC, PPP, Frame delay etc. Regardless of WAN encapsulation used it must be identical on both sides of the point to point link.

Packet and Circuit Switching

Circuit switching and packet switching are both used in high-capacity networks.
The majority of switched networks today get data across the network
Through packet switching.

Circuit-switching is more reliable than packet-switching. Circuit switching is old and expensive, packet switching is more modern.

General Routing Issues

What is a Routing Protocol?

A routing protocol is a protocol that specifies how routers communicate and exchange information on a network. Each router has prior knowledge of its immediate neighbors and knows the structure of the network topology. The routers know this because the routing protocol shares this information.

Protocol

RIP (Routing Information Protocol) was one of the most commonly used protocols on internal networks. Routers use RIP to dynamically adapt changes to the network connections and communicate information about which networks routers can reach and the distance between them. RIP is sometimes said to stand for Rest in Pieces in reference to the reputation that RIP has for breaking unexpectedly and rendering a network unable to function.

Routing Algorithms

Distance Vector

This type of routing protocol requires that each router simply inform its neighbors of its routing table. The distance vector protocol is also known as the bellman-ford algorithm.

Link State

This type of routing protocol requires that each router maintain a partial map of the network. The link state algorithm is also know as Dijkstra's algorithm.

IGRP

IGRP is a type of distance vector routing protocol invented by cisco used to exchange routing data in a autonomous system. Distance vector protocols measure distances and compare routes. Routers that use distance vector must send all or a portion of their routing table in a routing update message at regular intervals to each neighbor router.

Addressing and Routing

What does routing mean?

Routing is the process of deciding how to move packets from one network to another.
The directions also known as routes can be learned by a router using a routing protocol then the information is passed from router to router along the route of the destination.

IP Address's

Every machine connected to the internet is assigned an IP address. An example of an IP address would be 192.168.0.1. IP addresses are displayed in decimal format to make it easier for humans to understand but computers communicate in binary form. The four numbers that separate an IP address are called Octets. Each position consists of eight bits. When added to together you get 32 ​​bit address. The purpose of each octet in an IP address is to create classes of IP addresses that can be assigned within a network. There are three main classes that we deal with Class A, B and C. The octets of an IP address are split into two parts Network and Host. In a class A address the first octet is the network portion, this determinates which network the computer belongs to, the last octets of the address are the hosts that belong to the network.

Sub netting

Sub netting allows you to create multiple networks within a class A, B or C address. The subnet address is the address used by your LAN. In a Class C network address you would have a subnet mask of 255.255.255.0. A subnet mask identifies which portion is network and which is host. For example 192.168.6.15 the first octet three octets are the Network address and the last octet being the host (Workstation). It is important to subnet a network because gateways need to forward packets to other LANS. By giving each NIC on the gateway an IP address and a Subnet mask it allows the gateways to route packets from LAN to LAN. Once the packet arrives at its destination, the gateway then uses the bits of the subnet portion of the IP address to decide which LAN to send the packets.

Circuit Switched Leased Lines

A circuit switched network is one that establishes a dedicated circuit (or channel) between nodes and terminals before the users may communicate. Here are some terminologies associated with a Circuit switched network.

Frame relay is a telecommunication service designed for cost-efficient data transmission between local area networks (LANs)

Basic rate interference is a service used by small business for internet connectivity. An ISDN BRI provides two 64 Kbps digital channels to the user.
Primary rate interface (PRI) is a telecommunications standard for carrying voice and data transmissions between two locations
All data and voice channels are ISDN and operate at 64kbit / s

Packet Switching

Http://www.raduniversity.com/networks/2004/PacketSwitching/main.htm – _Toc80455261

Packet switching refers to protocols in which messages are broken up into small packets before they are sent. Each packet is then transmitted over the Internet. At the destination the packages are reassembled into the original message. Packet switching main difference from Circuit Switching is that that the communication lines are not dedicated to passing messages from the source to the destination. In Packet Switching, different messages can use the same network resources within the same time period.

Http://en.wikipedia.org/wiki/Asynchronous_Transfer_Mode

Asynchronous Transfer Mode (ATM) is a cell relay, packet switching network and protocolwhich encodes data into small fixed-sized cells.

ISDN is used to carry voice, data, video and images across a telephone network. ISDN stands for integrated services Digital Network. Isdn also provides users with a 128kbps bandwidth. This is done through frame relay. Frame relay complements and provides a service between ISDN, which offers bandwidth at 128 Kbps and Asynchronous Transfer Mode which operates in somewhat similar fashion to frame relay but at speeds from 155.520 Mbps or 622.080 Mbps. Frame relay is based on the older X.25 packet switching technology and is used to transmit analogue signals such as telephone conversations.

PSDN stands for packet switched data network and is a data communication network. Packet switched networks do not establish a physical communication signal like the public telephone circuit (circuit switched network) Packets are sent on a fixed length basis and assigned with a source and a destination address. The packages then explicitly on the routers to read the address and route the packets through the network.

Mobile and Broadband Services

Digital Subscriber Line (DSL) is mainly used to bring high bandwidth connections to homes and small business's over a copper wire telephone line. This is can only be achieved if you stay within the range of the telephone exchange. DSL offers download rates of up to 6mbps allowing continuous transmission of video, audio and 3D effects. DSL is set to replace ISDN and compete with the cable modem in providing multimedia to homes. DSL works by connecting your telephone line to the telephone office over copper wires that are twisted together.

Asymmetric Digital Subscribers Line is most commonly used for home users. It provides a high download speed but a lower upload speed. Using ADSL, up to 6.1 megabits per second of data can be sent downstream and up to 640 Kbps upstream.

Http://en.wikipedia.org/wiki/Symmetric_Digital_Subscriber_Line

Symmetric Digital Subscriber Line is a digital subcriber line which runs over one pair of copper wires. The main difference between ADSL and SDSL is the difference in upload and download speeds. SDSL allows the same upstream data rate and downstream data rate as ADSL upstream can be very slow.

[Http://searchnetworking.techtarget.com/sDefinition/0],,sid7_gci558545,00.html

HDSL High bit-rate Digital Subscriber Line, one of the earliest forms of DSL, is used for wideband digital transmission within a corporate site and between the telephone company and a customer. The main characteristic of HDSL is that that provides equal bandwidth in both directions.

IDSL is a system in which data is transmitted at 128 Kbps on a regular copper telephone line from a user to a destination using digital transmission.

The Local Loop enables operators to connect directly to the consumer via copper local loops and then add their own equipment to offer broadband and other services. This process involves operators accessing local exchange buildings to connect to a network of copper lines which connect them to homes and businesses. BT is an Example of a Local Exchange. The local loop connecting the telephone exchange to most subscribers is capable of carrying frequencies well beyond the 3.4 kHz upper limit.

Benefits of using DSL

DSL can provide a virtual instantaneous transmission of voice, data and video over ordinary copper phone lines. A DSL connection can eliminate delays while waiting to download information and graphics from the Internet. It provides users with a cost effective high speed Internet connection. Another benefit is that a DSL connection is always on-line (like a LAN connection) with no waiting time for dialing or connecting.

There are now more than 10 million broadband connections in the UK. By December 2005 there were 9.792 million broadband connections in the UK and the average broadband take up rate during the three months to December was more than 70,000 per week.

7 Top Reasons Why You Need to Upgrade the Memory For Your Computer

Are you dissatisfied with the way your computer works at a snail's pace? Do you have trouble running multiple programs at a time in a multitasking Operating System like Windows? Does it take ages for your computer to run programs? Can you take a coffee break while your computer opens an icon that you double-clicked? Do games and other resource-intensive programs frequently crash on your computer? If your answer to all these questions is a YES, then you need to think about upgrading your computer.

Upgrading your computer is not a joke, as random upgrades can be quite expensive. A processor upgrade frequently involves upgrading several other components to keep in pace with changes in technology and could be one of the most expensive options. Upgrading other components like graphics card or sound card alone is also not the optimal solution as performance improvement is limited to these areas alone.

Here are some reasons why it makes sense to upgrade the memory in your computer:

1. Cost-Performance Benefit – The upgrade cost versus performance boost ratio is greatest for a memory upgrade as compared to other component upgrades.

2. Programs Run Faster – The availability of RAM can speed up programs and save significant time hitherto wasted while waiting for a response from the computer.

3. Better Multitasking – Multitasking environments like Windows highly heavily on memory to function and increasing memory can provide better performance especially with concurrent running programs.

4. Enhanced Entertainment – Gaming and streaming media applications can benefit tremendously in both performance and speed by a memory upgrade.

5. Advanced Hardware and Software – With increase in memory capacity by upgrading, newer hardware and software components that went hitherto unused due to less memory can now be used.

6. Delay Costlier Upgrades – Memory upgrades to improve performance can defer other upgrades like processor upgrade that necessitate greater expenditure through a major revamp of the computer.

7. Improvement in Data Access Speed ​​- Greater amount of RAM can improve the speed at which the processor does data access and significantly increase the speed of execution.

Determining the Best Type of Fastener to Use For Outdoor Furniture Construction

If you want to learn about selecting hardware for your next outdoor furniture project, then you'll want to read this article. Specifically, I'll be telling you about what type of hardware will perform best, why the type of metal used for fasteners and the finish used are important considerations, and how properly protecting or limiting exposure of your furniture to wet and winter conditions can increase Life span. After you're done with this article you will understand that the best choice of hardware for your outdoor furniture project is dependent on furniture style, material used for construction, selected location for the furniture and budget.

Selecting proper hardware for your furniture will help ensure a long life span, as well as improve the overall appearance of your furniture. Part of the problem is knowing what hardware to select when there are so many options available at the hardware store. The typical Lowes or Home Depot carries a huge selection of stainless steel, hot dipped galvanized, bright galvanized, plain steel, coated steel and brass bolts, nuts, washers and screws. Each type of fastener is suitable for certain applications, but not all are ideal for outdoor furniture applications.

In fact, choosing the wrong fasteners can greatly shorten the lifespan of your furniture, contribute to rot of wood furniture, cause unsightly staining, and even make your furniture unsafe to use.

One thing that needs to be noted right up front is, do not ever use unprotected steel fasteners for outdoor furniture, they will rust very quickly, and the steel will react with the tannic acid in the wood causing streaks and staining. The tannic acid actually speeds up the corrosion of the fasteners. Have you ever seen a wooden fence with black streaks running down the boards from the nails? This fence was installed with the wrong type of fasteners. The same thing will happen to your furniture. Even worse, as the fasteners rust, they will speed up the decay process of the wood around the rusted fasteners, ruining your furniture and making it potentially unsafe to use.

Hot Dipped Galvanized

Screws and bolts treated by hot dipped galvanizing are specifically designed for use outdoors. Electroplated galvanized or bright galvanized fasteners will very well not hold up as well as the hot dipped galvanized hardware. Zinc is used as a coating in both methods, and acts as a barrier against the elements and the tannic acids in the wood.

I strongly recommend only using screws or bolts in the construction of outdoor furniture, however. The galvanized finish on nails, either electroplated or hot dipped, can easily become damaged while hammering them in, exposing the nail head to the elements and allowing them to begin rusting quickly.

Adequate care must be taken when installing galvanized screws. Drill pilot holes in hardwoods, and be sure to use a bit that is not worn and intolerable to skipping in the screw head. For whatever reason, the galvanized screws seem to not be as well tempered as other steel fasteners, and are more likely to either snap off or have the heads strip out while installing them. Due to the permission required for the hot dipped coating, galvanized bolts do not have as tight of tolerance on the threads, and are more likely to strip if over tightened.

Hot dipped galvanized fasteners are a fine choice for many outdoor furniture applications, including Adirondack Chairs, but are not the best choice for use in woods, such as teak.

Stainless steel

Stainless steel is the best choice for use in woods with higher levels of tannic acid, such as teak. Stainless steel is an alloy or blend of steel, nickel and chrome. The ratio of the other metals with the steel determine the weather and corrosion resistance of stainless steel. Because the steel is mixed with other softer metals, the stainless steel is not as strong, so predrilling of screw holes is highly recommended in all applications, and essential in hardwoods such as teak and mahogany. The added corrosion resistance more than outweighs any shortcomings that the metal may have, especially in outdoor furniture applications.

While stainless steel fasteners are the most rust resistant, they are also the most expensive of the options we are discussing. However, using stainless steel fasteners will add years of life to your furniture. In the respect, they are an investment that will pay out for years to come.

Brass

I have seen brass used in some commercially produced outdoor furniture, but do not recommend it. While brass does not form red rust, and is well suited for many wet applications such as toilets and sinks, it does tarnish and corrode. It is also very susceptible to the tannic acids in wood, which will cause it to fail more quickly. Brass screws in particular Do not have sufficient strength for outdoor furniture applications.

Outdoor or deck screws

In the past several years a number of manufacturers have introduced outdoor fastening products specifically marketed for deck building. These will typically be green, gray, tan or brown. These screws are either ceramic or plastic coated to delay the metal reacting with the wood acids. The specific coating methods are proprietary to each manufacturer, and can be a combination of electroplated galvanizing and plastic, or a baked on ceramic.

I have used these fasteners in furniture applications and they perform just fine. Unfortunately, I have not come across bolts with this type of finish. The brand of screw I used was Deck Mate, and they were available in tan and brown, so that the color can be selected to better match the wood being used. These screws are ceramic covered, and the manufacturer provided a coated bit for installation, which was designed to not damage the ceramic coating at the screw head. If you choose this type of fastener, be sure to compare the cost with stainless steel, as the price will vary. If the stainless steel is reasonably comparable in cost, it would be the recommended fastener.

Always be sure to read the manufacturers specifications on the box to be sure that the screws are suitable for your application.

Other Considerations

If you are building furniture that will be located on a covered porch or patio where it will be protected from the elements, the concern will be the interaction between the wood and the fasteners, much more so than the weather. Furniture that will be exposed to the elements all year, such as a garden bench, or an adirondack chair in the corner of your garden, will have to be constructed with much more care and concern to ensure that they hold up more than just one or Two winters.

Additional considerations must be made beyond just the choice of what type of fastener to use, though this is very important. For example, fasteners should not be located where water where collect and sit on the fasteners for an extended period of time. The screws that attach the seat slats to an Adirondack chair are a prime example- typically these screws will be countersunk below the surface of the wood. This will allow water to collect in the screw holes, shortening the life span of all but stainless steel fasteners, and prolonging the exposure of the wood to water, which will increase the rate of decay. In applications where the furniture will be exposed to the elements year round the screw heads should be driven flush with the surface of the surrounding wood.

Construction and design of the furniture are also important considerations. Are the horizontal surfaces of the furniture constructed in such a way that will allow them to shed water, rather than collect it? Think of a picnic table with a slatted or board top. The gaps between the boards allow water a way to run off the top and not pool up.

Conclusion

Stainless steel is usually the best choice for outdoor furniture applications, although the cost may be prohibitive for some. There are other less expensive fastener options available that will perform acceptably. Do not use unprotected steel fasteners for outdoor furniture applications under any circumstances. Know where and how you intend to use your furniture and design it for the conditions it will be subjected to.
