x definition

X may refer to any of the following:

1. In general, a x is used to represent a generic variable. For example, you may see Computer Hope and other companies list Microsoft Windows 3.x. In this case, the "x" can be replaced with any valid digit. For instance, it may represent the "1" in Windows 3.1 or the "11" in Windows 3.11.

2. When referring to a computer CD drive, an X refers to the transfer speed. For example, the original 1X CD-ROM had a speed of 153,600 BPS, and a 24X CD-ROM has a BPS of 3,686,400 or 153,600 x 24. The higher the number, the faster data is going to be read from the CD drive. See the CD-ROM definition for further information about transfer speeds.

3. In mathematics, an x may be used to represent a times sign. For example, 4 x 4 = 16. The times sign may also be represented as an interpunct (∙) or an asterisk (*).

4. X is a service found on some IRC networks that allows users to manage the chat rooms, called channels, that they have access to view.

5. Abbreviation for X window system. See the x command page for further information about this command.

6. In chat, 'x' or 'X' is a way of representing a kiss. For example, "xoxo" is kiss, hug, kiss, and hug.
