Answer 2

A network is, like others say, 2 or more computers or devices that can talk to each other.



The reason networks were created in the first place was for military personnel to communicate to each other quickly. It was very secure because it was never heard of before, unlike phone systems, other military didn't know how to penetrate it.



Networks now are used for data transffering/sharing, the internet being the biggest network. It actually started out in the western part of the US with 7 routers spanning, I believe, 3 or 4 states, with under 250 people using it.



Sorry just a little history there lol Ahh, I'm such a geek... lol

A network is pretty much a bunch of computers that are connected together.
