Exception: An event that causes suspension of normal program operation.

End user: Any individual who uses the information generated by a computer based system.

Font: In a simplistic sense, a font can be thought of as the physical description of a character set. While the character set will define what sets of bits map to what letters, numbers, and other symbols, the font will define what each letter, number, and other symbol looks like.

Format: (1) Noun: The logical or physical arrangement of the tracks and sectors on a floppy diskette or a hard disk. To be usable, a disk must be formatted so that the tracks and sectors are laid out in a manner compatible with the operating system in use.

Fax: It stands for faccismile machine. It is used to transmit a copy of a document electronically.

Failure: The inability of a system or component to perform its required functions within specified performance requirements.

Fault: An incorrect step, process, or data definition in a computer program which causes the program to perform in an unintended or unanticipated manner.

Fiber optics: Communications systems that use optical fibers for transmission.

Firmware: The combination of a hardware device; e.g., an IC; and computer instructions and data that reside as read only software on that device. Such software cannot be modified by the computer during processing.

Flag: A variable that is set to a prescribed state, often «true» or «false», based on the results of a process or the occurrence of a specified condition.

Gopher: A program that searches for file names and resources on the Internet and presents hierarchical menus to the user.
