Unix is a portable, multi-tasking, and multi-user operating system. Unix systems are characterized by various concepts: the use of plain text for storing data; a hierarchical file system; treating devices and certain types of inter-process communications (IPC) as files; and the use of a large number of software tools, small programs that can be strung together through a command line interpreter using pipes, as opposed to using a single monolithic program that includes all of the same functionality. There are numerous offshoots of Unix that operate similarly, notably Linux (these variants are often referred to collectively as “*nix”).
Where It Fits
Much of the Internet operates on *nix-based machines. If you want to control, manipulate, and safeguard your web content, you need to know how to administer the machines on which it resides. Most jobs in web development and IT in general will require at least some knowledge of Unix, and likely will require fairly deep knowledge. Also see the Linux Systems Administration courses and Certificate Program.
Unix was first developed by AT&T employees at Bell Labs in 1969, and has a long and storied history.
