Topic Notes - INTERNET
What is internet ?? Why is internet ?? How will it affect me ??
The Internet was started as a result of the "Cold" war during the 1960s. It started as a way to send information to and from Military sites.
During the 70s and 80s, colleges and Large companies were added to this network because they were involved in military research and needed a way to communicate with others working on the same projects. During the 90s, individuals began connecting through companies such as AMERICA ONLINE.
