The Internet

Extracts from this document...

Introduction

The Internet The Internet is like a network of networks where any computer can link up to information stored within it. It is accessed by a telecommunications line and a modulator-demodulator (MODEM). It is brought to your computer screen by converting analogue telephone signals into digital computer signals. There are many advantages and disadvantages on the Internet. The main advantage of the Internet is that communication is made very easy. Two people on opposite sides of the world may communicate with each other via such things as videoconferences. This would save money on flights to other countries just to have a meeting when they can each communicate from their own office. The Internet is a very good place to advertise companies. Businesses can build their own websites and buy their own memorable .com domains. This can be where they explain their company and the services they offer. Some can even offer home delivery directly from the Internet with things such as home shopping. This makes life very easy for disabled people or people with busy lives who have no time to go shopping. Other services the Internet has to offer are things such as Online Banking. This is often quicker and easier for people so that they can carry out transactions over the web to anyone in the world without the hassle of writing cheques. ...read more.

They can make use of the Internet to communicate with the main work place and send their work through it. The information it provides can be viewed in a much better quality than previous interactive sources of information. For example, Teletext found on some televisions has only a small range of colours and cannot support clear images; it does not have the memory for as many pixels as a computer. There are also many disadvantages of the Internet. The Internet does provide downloads but some of these downloads may infringe copyright rulings. The best example of this is the mp3 downloader Napster. This allows people to save music to their hard drive, some of which is protected by copyright. This is cheating the artists who made these singles because people are getting them for free. People can also download things like illegal or pirated software. People can access explicit sites too such as hate, racist or pornographic. The London bomber of Brick Lane found information on creating bombs from an Internet site. It is also dangerous for children to access pornographic sites without these being blocked. It is, of course, impossible to block every site. The Internet is full of viruses and hackers. Hackers can send viruses to your PC and, unless you have a virus checker, you cannot correct the damage it does. ...read more.

Conclusion

There is much controversy over privacy on the Internet. Whenever we access a site, something called a "cookie" is stored on our computer to track our behaviour with this site. Some people see this is an infringement of our right to anonymity. Some people are also worried about how much information can be gathered from our PC and stored by sites. There are a lot of fraud possibilities on the Internet. Any site could set themselves up, tricking you into giving them your credit card details so that they can steal money off you. People's trust in the Internet is becoming far too great. Another disadvantage of the Internet is one actually needing a credit, debit or switch card to purchase things. If you do not have one of these cards you cannot make use of services such as Home Shopping. A problem with relying on e-mail is that it may not always be appropriate. For example, if you urgently needed to get hold of someone, you would not get a reply until the recipient checked their mailbox. In this kind of situation something like a phone would be better. Another disadvantage is that it is becoming impossible to get by without the Internet. All over television and radio, Internet sites are advertised. Some information is exclusively available over the Internet, which deprives people who cannot access it of this privilege. ?? ?? ?? ?? X:\My Documents\Config\Normal.dot ...read more.
