EC285 Lecture Notes - Lecture 7: Sri International, Internetworking, Arpanet
Document Summary
A (very large) collection of computer networks. A set of specifications describing how those networks and the computers within them communicate with one another. Unlike ethernet and wireless ethernet (ieee 802. 11), the internet"s specifications make no assumptions about network hardware. The specifications -called protocols - are aimed at software-to-software communications. The details of how information actually gets from one point to another is handled separately (by hardware-controlling technologies like ethernet) The protocol underlying (supporting) all other protocols on the internet is called the internet. Note for future reference that a lan may -and likely does -use ip to assist in its own communications, whether it is actually connected to other networks or not. We have a computer scientists named j. c. r. Lick licklider to thank for first envisioning the general form the internet would eventually take way back in august 1962, in memos he wrote on the topic of an intergalactic computer network .
