Document Summary
Objective 1: recognize the importance of the internet. Concept 7. 01: looking back: how the internet got started. Arpanet: (1960s) to design a communications system that had multiple pathways through which information could travel so that losing one part of the system would not cripple the whole system. The original arpanet only had 4 locations called nodes; ucla, stanford research. Institution (sri), university of utah in salt lake city, & ucsb. (1979) the national science foundation (nsf) created csnet to connect the university computer science departments using the arpanet technology. Nsf created nsfnet, giving other academic disciplines access to supercomputing centers & connecting smaller networks together. (mid-1980s) Internet backbone: the high-speed connection points between networks. Internet: (net) the physical entity--a network of computer networks. The internet is a public network, but the networks it connects can be public or closed, private networks. World wide web: (web) the hypertext system of information on the internet.
