The Internet has revolutionized the way we communicate in society. It has opened up another channel of communication. All conventional forms of communication including telephone, radio, television and mail have all had to adapt to include the internet in the communication medium. However, the difference between the other mediums is quite unique, the Internet provides everyone the ability to express their own opinion, whether biased, truthful or corrupting to a global audience. While it has brought many positive aspects to society for example 'email', it has raised many ethical, sociological and moral questions.
There were an estimated 604,111,719 internet users by the year 2002 est.
Historically, internet began with Paul Baran's study, which proposed the idea of a packet switched network. This idea was then implemented in 1969 between four universities in the United States. These networks evolved and expanded from United States to throughout the world, and these inter-connected networks all using the same TCP/IP protocol are considered to be what the Internet is.
Internet and World Wide Web
The Internet is essentially an infrastructure that allow computers to link together through a sets of computer networks. Using this existing infrastructure, Tim Berners-Lee wrote the Hypertext Transfer Protocol (HTTP). Hypertext documents allow documents to be linked to other documents so using this protocol created by Berners-Lee allowed to give documents addresses on the internet.
