 UNIX

UNIX is the trademarked name of the multiuser, multitasking, time-sharing operating system developed at AT&T's Bell Labs in 1969. Many websites are maintained on UNIX systems. While technically the name UNIX refers to only a few trademark-licensed versions, it is often used to refer to the many versions currently available on the market. The differences to the user are slight.

 URL

An acronym for Uniform Resource Locator, a URL is the address for a resource or site (usually a directory or file) on the World Wide Web and the convention that web browsers use for locating files and other remote services.

 Upgrade

An upgrade is a later release of a software program. Most software companies work to improve their existing software by upgrading it periodically by adding new features and functions.

 Uploading

Often confused with downloading, uploading a file means loading it from your computer onto a remote one. Most people do a lot more downloading than uploading.
