2. THE GREATEST INVENTION OF THE LAST 50 YEARS: THE INTERNET

Describe the invention  The Internet is a worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web.

14.  Nobody would have an internet job  We wouldn’t have access to an infinite amount of information  We would be living in a totally different world and it would feel a lot smaller  The spread of information would come to a screeching halt (65% of the people get their news online)  Revolutions would take longer; tens of thousands of demonstrators wouldn’t have staged rallies in 900 cities around the world. The world would be different but definitely not better.

16. 1. The Internet and freedom of speech o No-one owns the Internet so anybody can post anything on it. o The Internet is a great source of information but it has also become the home of political propaganda, racism, pornography and other controversial or illegal material. o Apart from physically restricting access the only control is through some form of filtering software. o Increasingly individuals and authorities are recommending some sort of control.

17. Arguments for control To prevent illegal material being readily available, e.g. political propaganda, racism and pornography. To prevent young children accessing unsuitable material. To make the Web more efficient - at present there is too much useless information. To ensure copyright laws are maintained.

18. Arguments against control The aim of the Internet is to be a free source of information. Unsuitable material is easily available in other ways. Control would cost money and users would have to pay. Control would be very difficult to enforce.

19. 2. Internet crime New technology brings with it new crimes and as a result some governments are setting up special units to deal with Internet crime. Concerns surround: the interception of credit card details and transactions online. hacking into personal, private files with criminal intent. fraudulent web sites taking credit card details from customers. the spreading of viruses through the Internet.

20. 3. Internet security A number of steps are being taken to reassure the general public that the Internet is safe: D ata is encoded before transmission using encryption techniques which scramble the data. The data is then decoded at the receiving end (decryption). The use of passwords and access level restrictions. The use of firewalls (servers that filter incoming messages to protect LANs from viruses and hacking). Tough penalties for offenders under the Computer Misuse Act.
