The creation

The idea was developed by the Department of Defense (DOD) in the USA. Initially it was created so that the officials had a way of communication, in the event that an atomic bomb.

It was APRANET when they first arrived in 1969. Slowly the network to develop and grow with the number of users, so that at 550 users in 1981 and 940 users in 1984.
