Dear Readers, Here we have given the list of important Computer Awareness Glossary, Candidates those who are preparing for the upcoming Banking exams can use this.

Ethernet: A transport method (protocol) used to connect computers to a LAN (Local Area Network) and exchange data.

Embedded computer: A device which has its own computing power dedicated to specific functions, usually consisting of a microprocessor and firmware.

Error: A discrepancy between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition.

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

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

File: (1) A collection of related records. (2) A named area on a disk-storage device that contains a program or digitized information (text, image, sound, and so on). (3) A component of an overall program or application.

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.
(2) Verb: To prepare a disk or diskette, dividing it into sectors so that it is ready to receive data.

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. As users select options, they are moved to different Gopher servers on the Internet. Where links have been established, Usenet news and other information can be read directly from Gopher. There are more than 7,000 Gopher servers on the Internet.

Gigahertz: One gigahertz is equivalent to 1000 megahertz, or 1,000,000,000 hertz.

Hacker: An individual with vast experience with security protocols who attempts to illegally access secure servers in an attempt to download private information, damage systems, or act in some other way to “free information”.

Hard Copy: A readable printed copy of computer output.

Hard Disk: Hard disk (internal) is a permanent file and data storage device housed in a computer case.

Home Page: The Web page which is the starting point for accessing information at a site or in a particular area.

Host: A computer, attached to a network which provides services to another computer beyond simply storing and forwarding information.

Handshake: An interlocked sequence of signals between connected components in which each component waits for the acknowledgement of its previous signal before proceeding with its action, such as data transfer.

Hazard: A condition that is prerequisite to a mishap.

Hertz: A unit of frequency equal to one cycle per second.

Hexadecimal: The base 16 number system. Digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, & F. This is a convenient form in which to examine binary data because it collects 4 binary digits per hexadecimal digit; e.g., decimal 15 is 1111 in binary and F in hexadecimal.
