Visualwize Chess Training Software: A Review

Chess enthusiasts of all levels are always seeking ways to improve their chess skills, so that they can win at chess games, whether they play professionally or socially.

One of the most effective ways to improve your chess skills is to use a chess visualization software, which enables you to practice and improve your visualization skills. Visualization is one of the most important skills you need to succeed in chess.

A program that is apparently gaining a lot of popularity and is helping many people to improve their chess is Visualwize Chess Training Software.

Let’s address the basic questions on this software.

What is it?

Visualwize is a chess training software that trains your ability to have a clear mental picture of chess moves before you make these moves on the board. This enables you to assess the implications of your moves before you make the actual moves. This therefore enables you to play better at chess, as you will be able to make the right decisions and avoid making some mistakes that would make you lost a game.

This program has 240 visualization training exercises which are designed to develop your visualization skills. It has and more than 1200 moves to visualize. These moves are real moves made by a master player in real chess games. With the software, you can train to visualize up to 8 moves ahead.

The program consists of 4 levels, level 1 being rather easy and level 4 being hard. You can order the level that suits your needs. For those who really want to significantly improve their skills, level 4, the complete program, is recommended.

How does it work – what does the program actually do?

In simple terms, the program shows a chess position from a game between two chess masters, and then, with arrows, it shows the next few moves that have been made in that position by the renowned chess masters. The arrows stop in a position where a tactic, i.e., a combination that wins the game exists.

Unlike other programs and books that use written annotations for the moves, this program uses arrows on the board. This means it reflects a realistic playing scenario, and you don’t have to take your attention and eyes from the board to read written annotations.

This is one major factor that separates this program from others that are available on the Internet today. Rather than building up the skill of moving your eyes between notation and the board, Visualwize trains you in the art of seeing unfolding moves without actually affecting the board.

On the website where the program is offered, there are many informative and short videos that you can watch, which describe how the program works.

Why is it important – what benefits can you get from this program?

It is recommended that chess players wanting to take their chess to the next level use this program because it offers several benefits:

  • You will be able to see more chess moves ahead, before you actually make any move on the board, giving you an opportunity to assess the consequences of every move before you make it.
  • You will avoid making mistakes which can make you lose a game in an instant.
  • You will make the most of your training time since you will be able to easily visualize the notation below chess diagrams.
  • You become an efficient and effective chess player – you won’t need to calculate variations several times over because you will be able to clearly the consequences of your move in your mind, saving you a lot of time.
  • You will make a wise investment that will help you significantly improve your chess – the program is favourably priced at only $30. If you were to hire a chess coach, you would pay a very high fee per hour of the coach’s time to train you.
  • It is convenient – once you purchase the program, you can train at any time of the day or night, as much as you want.

With several books and programs on how to improve chess, available today, Visualwize is considered to be a cut above the rest among many chess enthusiasts.

Five Reasons to Study Forensic Accounting

Forensic accounting is the practice of utilizing accounting auditing and investigative skills to assist in legal matters to obtain an accurate result to establish the accountability for administrative proceeding. You may be wondering, why study forensic accounting?

Well, here are the five reasons:

  • Our current economic crisis has left many companies to face serious financial issues that may lead to bankruptcy. Hence, these companies have been forced to stoop down to the lowest level to save their company by committing frauds and swindles. This makes such a job an important one that increases in demand each year.
  • Internal audit in the company could not throw light on the different fact and other hidden aspects of the corporate fraud. They are hardly in a position to initiate proper action at proper time due to their lack of forensic accounting skills.
  • Forensic accounting is a new and very exciting study. This change the perspective of the world on accounting study, which has been a theoretically dull field in itself.
  • If you are ambitious, fast, observant, creative and diligent, Forensic accounting is definitely a dream job and a great investment. Using computer technology, creative thinking, and careful inspection of financial records; the hidden proof of the crimes can be discovered.
  • You will always be equipped with the latest computer software and gadgets. Forensic accounting heavily relies on computer software and generalized audit software to aid in the detection and investigation of fraud and white-collar crimes. Also, investigative tools such as data mining, link analysis software and case management software and the use of the Internet are the essential skills as well.

In conclusion, forensic accounting has been stereotyped as a boring and uninteresting job which has been proved to be wrong. There are many reasons which show to be benefits when it comes to studying forensic accounting. Not only will you be rewarded with a stable job, you would also look forward to going to work everyday

How to Change the MPI Node Address For a Siemens S7-300 PLC

I have seven Siemens S7-300 PLCs connected together using the MPI (Multi Point Interface) interface. The Siemens MPI protocol is used by Siemens PLCs to communicate with external devices. I want to rename each of the seven PLCs. Here are the steps to accomplish that task.

First, connect your MPI cable to the first PLC. I will be connecting my laptop to each PLC individually. Power up the PLC and open Simatic Manager. The "New Project" Wizard window will open. Just click Cancel to close the window. Now click the Accessible Nodes icon on the toolbar. A window will open showing the identification of the PLC you are connected to. My window is showing MPI = 2 (directly). Make a note of this address and close the window.

Next we need to download a hardware configuration to the PLC. This is where we will rename the PLC node address. There are probably a couple of different ways to do this – following is how I accomplish this. All seven of my PLCs are the same model; Therefore, I am using the same hardware configuration. For the obvious reasons, I want to give each a different MPI node address. I have a project file that contains all seven of my PLC programs and one hardware configuration file. I open the one hardware configuration file, and then double click Hardware in the right hand window. This will open the HW Configuration window. In this window you should see your PLC with its MPI address given.

Remember when we clicked the Accessible Nodes icon and saw MPI = 2 (directly)? My Hardware Configuration Window is showing a MPI address of 7. Place your mouse cursor on the 7 and double click. Your CPU Properties window will open. It should open to the General tab. Look down and you will see Interface Type MPI with an address of 7. Click Properties and the MPI interface Properties window will open. Using the pull down menu, choose your MPI node address and make sure the MPI (1) 187.5kbps is highlighted and click OK. You are now back on the CPU Properties window where you will see your address has changed. Click OK and you will go back to the Hard Ware window where you can verify your MPI node address has changed.

You will now click the Save and Compile icon and then click the download icon. The Select Target Module window will open. Click OK and the Select Node Address window will open. Here you will see the MPI node address you assigned earlier. You will need to click the View button right below this. You will see the current node address appear, this should be the same as what you saw earlier when you clicked the Accessible Nodes icon. Simply click on this number and you will see it appear in the MPI address slot under the Enter connection to target station. Click OK and the Download to Module window will open. Click OK and the Stop Target Modules window will open. Click OK and the "Do you want to start the module?" Window will open. Click Yes.

Now go back to the SIMATIC Manager window and click the accessible nodes icon. You will see your new MPI node address. You can see this same article with pictures at http://www.morerobototics.com .

Advantages of Antispyware Programs

Much like the antivirus programs, now a days anti spyware programs also is a must if you are browsing the net. Most of the antivirus programs provide a good job by taking care of the computer viruses. However, many of them fail to detect the spyware which gets installed onto the PC when connected to the internet. This is where Anti spyware programs comes to help. They do a good job by protecting our computers by identifying the spyware and promptly remove them.

There are so many antispyware programs are available in the market. Both in the Online as well as near to your computer retail showroom. However, you have to ensure that you buy a good Anti spyware program which fulfills the requirements what it promises. Also, make sure to check that the software works on your Operating System. Most of them work on Windows Operating system; however, there is no harm in double checking the same.

Some of the characteristics of a good antispyware program is as below.

Real time scanning

Real time scanning is the heart of these type of programs. The program once installed should reside on your system tray and should be able to do a real time scan in the background. This way it should be able to identify all kinds of threats like Adware, spyware, Trojans and the harmful key loggers.

Automatic Updates

There is no point in having an Antispyware software program which does not update the spyware definitions automatically and at periodic intervals.

Customer Support

Most of the time you will not be require to call up their helpdesk as the software will work automatically provided if the operating system is compatible and all the installation prerequisites are met. However, if you run across any installation problems or some kind of bugs customer service comes in handy.

Why Do We Need Software Engineering?

To understand the necessity for software engineering, we must pause briefly to look back at the recent history of computing. This history will help us to understand the problems that started to become obvious in the late sixties and early seventies, and the solutions that have led to the creation of the field of software engineering. These problems were referred to by some as “The software Crisis,” so named for the symptoms of the problem. The situation might also been called “The Complexity Barrier,” so named for the primary cause of the problems. Some refer to the software crisis in the past tense. The crisis is far from over, but thanks to the development of many new techniques that are now included under the title of software engineering, we have made and are continuing to make progress.

In the early days of computing the primary concern was with building or acquiring the hardware. Software was almost expected to take care of itself. The consensus held that “hardware” is “hard” to change, while “software” is “soft,” or easy to change. According, most people in the industry carefully planned hardware development but gave considerably less forethought to the software. If the software didn’t work, they believed, it would be easy enough to change it until it did work. In that case, why make the effort to plan?

The cost of software amounted to such a small fraction of the cost of the hardware that no one considered it very important to manage its development. Everyone, however, saw the importance of producing programs that were efficient and ran fast because this saved time on the expensive hardware. People time was assumed to save machine time. Making the people process efficient received little priority.

This approach proved satisfactory in the early days of computing, when the software was simple. However, as computing matured, programs became more complex and projects grew larger whereas programs had since been routinely specified, written, operated, and maintained all by the same person, programs began to be developed by teams of programmers to meet someone else’s expectations.

Individual effort gave way to team effort. Communication and coordination which once went on within the head of one person had to occur between the heads of many persons, making the whole process very much more complicated. As a result, communication, management, planning and documentation became critical.

Consider this analogy: a carpenter might work alone to build a simple house for himself or herself without more than a general concept of a plan. He or she could work things out or make adjustments as the work progressed. That’s how early programs were written. But if the home is more elaborate, or if it is built for someone else, the carpenter has to plan more carefully how the house is to be built. Plans need to be reviewed with the future owner before construction starts. And if the house is to be built by many carpenters, the whole project certainly has to be planned before work starts so that as one carpenter builds one part of the house, another is not building the other side of a different house. Scheduling becomes a key element so that cement contractors pour the basement walls before the carpenters start the framing. As the house becomes more complex and more people’s work has to be coordinated, blueprints and management plans are required.

As programs became more complex, the early methods used to make blueprints (flowcharts) were no longer satisfactory to represent this greater complexity. And thus it became difficult for one person who needed a program written to convey to another person, the programmer, just what was wanted, or for programmers to convey to each other what they were doing. In fact, without better methods of representation it became difficult for even one programmer to keep track of what he or she is doing.

The times required to write programs and their costs began to exceed to all estimates. It was not unusual for systems to cost more than twice what had been estimated and to take weeks, months or years longer than expected to complete. The systems turned over to the client frequently did not work correctly because the money or time had run out before the programs could be made to work as originally intended. Or the program was so complex that every attempt to fix a problem produced more problems than it fixed. As clients finally saw what they were getting, they often changed their minds about what they wanted. At least one very large military software systems project costing several hundred million dollars was abandoned because it could never be made to work properly.

The quality of programs also became a big concern. As computers and their programs were used for more vital tasks, like monitoring life support equipment, program quality took on new meaning. Since we had increased our dependency on computers and in many cases could no longer get along without them, we discovered how important it is that they work correctly.

Making a change within a complex program turned out to be very expensive. Often even to get the program to do something slightly different was so hard that it was easier to throw out the old program and start over. This, of course, was costly. Part of the evolution in the software engineering approach was learning to develop systems that are built well enough the first time so that simple changes can be made easily.

At the same time, hardware was growing ever less expensive. Tubes were replaced by transistors and transistors were replaced by integrated circuits until micro computers costing less than three thousand dollars have become several million dollars. As an indication of how fast change was occurring, the cost of a given amount of computing decreases by one half every two years. Given this realignment, the times and costs to develop the software were no longer so small, compared to the hardware, that they could be ignored.

As the cost of hardware plummeted, software continued to be written by humans, whose wages were rising. The savings from productivity improvements in software development from the use of assemblers, compilers, and data base management systems did not proceed as rapidly as the savings in hardware costs. Indeed, today software costs not only can no longer be ignored, they have become larger than the hardware costs. Some current developments, such as nonprocedural (fourth generation) languages and the use of artificial intelligence (fifth generation), show promise of increasing software development productivity, but we are only beginning to see their potential.

Another problem was that in the past programs were often before it was fully understood what the program needed to do. Once the program had been written, the client began to express dissatisfaction. And if the client is dissatisfied, ultimately the producer, too, was unhappy. As time went by software developers learned to lay out with paper and pencil exactly what they intended to do before starting. Then they could review the plans with the client to see if they met the client’s expectations. It is simpler and less expensive to make changes to this paper-and-pencil version than to make them after the system has been built. Using good planning makes it less likely that changes will have to be made once the program is finished.

Unfortunately, until several years ago no good method of representation existed to describe satisfactorily systems as complex as those that are being developed today. The only good representation of what the product will look like was the finished product itself. Developers could not show clients what they were planning. And clients could not see whether what the software was what they wanted until it was finally built. Then it was too expensive to change.

Again, consider the analogy of building construction. An architect can draw a floor plan. The client can usually gain some understanding of what the architect has planned and give feed back as to whether it is appropriate. Floor plans are reasonably easy for the layperson to understand because most people are familiar with the drawings representing geometrical objects. The architect and the client share common concepts about space and geometry. But the software engineer must represent for the client a system involving logic and information processing. Since they do not already have a language of common concepts, the software engineer must teach a new language to the client before they can communicate.

Moreover, it is important that this language be simple so it can be learned quickly.

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.

Advantages to Android Game Development

The industry of mobile game development has introduced a very important aspect to the market – the ability to conceptualize, develop, and release video games on devices with far more success and ease than ever before. And with the Android app marketplace only requiring a one-time fee for submitting an application, the cost becomes almost negligible to put the product out for millions of customers to find. Even the submission process is drastically shorter than on most other smartphones, as the app regulation is far more lenient for the Android OS.

Another drawing point for developing games on Android devices is the programming language featured- Java. Java has long been one of the most popular programming languages ​​for video game developers, and that makes it extremely easy for the average programmer to pick up Android development for the first time. Compared to most other mobile platforms, which usually sport modified or newly invented languages, the learning curve is decreed to nearly nothing, so a new developer can complete a game in a fraction of the time.

Another unique aspect to Android game development is the lack of standardization in the droid phone family. As the Android OS is not licensed to a single mobile phone making company, the phones themselves can vary to an extreme degree in terms of features and hardware specifications. While one device may have a fully functional A-GPS and HDMI video compatibility, another may have a QWERTY keyboard and no GPS at all. While this is certainly appealing to some developers, as they are likely to find a phone that will meet their hardware needs reasonably, it will also restrict the potential audience, as some phones will not be able to support the more complex applications.

When the game development process has finally reached the point where it can be released to the public, the developer is presented with yet another choice- which market would the game be most visible in? Unlike the iOS, there are numerous marketplaces and app stores for Android phones, each one with it's own advantages and disadvantages. From the basic Android marketplace, built to only display the apps compatible with the phone currently being used, to the Amazon app store, which offers a different free app every day, the myriad of marketing strategies can be almost daunting, which makes it all the More useful that an application can almost always be entered into multiple marketplaces without issue. However, whenever it makes sense to spread attention across several different fields is another question entirely.

The Android game development process overall really gives the most variety on the smartphone market. From start to finish, strategies can be hand-tailored to the developer's desires, making the game as close to the original concept as currently possible. While the audience may not be as large as that of iPhone users, the Android presents itself as a strong contender, purely through its accessibility. And with the largest variety of smartphones on the current market, the possibilities for development are inexhaustible, and continued releases can only add to the capabilities the platform has to offer.

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.

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.
