Document Summary
Modern marvels: the internet: behind the web (clip: http://www. youtube. com/watch?v=sducuvi5fri)origins of the internet. Early computers did not communicate with one another. Originally a comp sci program, then became space. Demand access you do(cid:374)(cid:859)t get it u(cid:374)til you (cid:374)eed it. Distributed control no one thing should control the network, each one has some control. Hot potato message gets where it is going even if part of network is destroyed. Ea(cid:272)h (cid:858)pa(cid:272)ket(cid:859) of i(cid:374)for(cid:373)atio(cid:374) is se(cid:374)t (cid:449)ith se(cid:374)der a(cid:374)d re(cid:272)ei(cid:448)er i(cid:374)for(cid:373)atio(cid:374), (cid:271)roke(cid:374) up data. Nodes would receive and send out packets like a post office, would keep a copy of the packet, kept sending it until it was received. Time sharing sit at terminal with q and a, put in queries, got response almost immediately. No two computers could talk to each other, had to keep moving around to talk to machines. Wanted a network in which one terminal could access.
