UNIX
An operating system, invented in 1969 at AT&T Bell Laboratories, that was made available to researchers and students in 1973. It was used to develop the Internet's communication software protocols. An interactive time-sharing system invented in 1969 by Ken Thompson after Bell Labs left the Multics project, originally so he could play games on his scavenged PDP-7. Dennis Ritchie, the inventor of C, is considered a co-author of the system. The turning point in UNIX's history came when it was reimplemented almost entirely in C during 1972--1974, making it the first source-portable operating system. UNIX subsequently underwent mutations and expansions at the hands of many different people, resulting in a uniquely flexible and developer-friendly environment. By 1991, UNIX had become the most widely used multi-user general-purpose operating system in the world.

URL - Uniform Resource Locator
Describes the location and access method of a resource on the Internet All Web sites have URLs. One could say a URL is to a web site as a telephone number is to a telephone or a street address is to a house. Although Web site URLs are sometimes long and hard to read, many browsers have a bookmark feature, which allows you to save the location (URL) of Web sites you want to return to. The URL "http://www.yourdomain.com" describes the type of access method being used (http) and the server location which hosts the Web site (www.yourdomain.com).
