Computer Awareness Daily Glossary:
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.
Laptop: Laptop is a small and lightweight computer in which all the main parts are fitted into single unit. It is designed to be carried around. Particularly, it is ideal for travellers, journalists, commentators and professionals who want to work both at the office and home.
LCD: Acronym for “Liquid Crystal Display”. It is the technology used for displays in notebooks and monitors for computers.
Linux: An open source spinoff of the UNIX operating system that runs on a number of hardware platforms and is made available for free over the Internet.
Log on & Log off: Each server that is accessed must have some way to ensure security of their sensitive information. Thus, servers restrict access by forcing users to “log on” with either personal access codes or anonymously. Anonymous access usually requires the individual’s e-mail address, and the user’s IP address is also logged. Once the desired information has been obtained, the user can “log off”, disconnecting access to the server.
Large scale integration: A classification of ICs [chips] based on their size as expressed by the number of circuits or logic gates they contain. An LSI IC contains 3,000 to 100,000 transistors.
Latency: The time interval between the instant at which a CPU’s instruction control unit initiates a call for data and the instant at which the actual transfer of the data starts.
Monitor: The high-resolution TV-like device that displays your computer’s output. Today’s monitors have much better quality displays than any TV is capable of producing.
Motherboard: is the core of a computer system. It is the circuit board where all other parts connect. It
communicates and controls the overall system. No motherboard means no computer system.
MP3: This stands for “MPEG I Audio Layer- 3” and is a digital. compressed music file (their file names always end with an mp3 extension). MP3 files are often downloaded or exchanged between people online.
MPEG: Acronym for “Motion Picture Experts Group” A video file compression system which is used on the web.
Multimedia application: Computer applications that involve the integration of text, sound, graphics, motion video, and animation.
Multitasking: The concurrent execution of more than one program at a time.
Macro: In software engineering, a predefined sequence of computer instructions that is inserted into a program, usually during assembly or compilation, at each place that its corresponding acroinstruction appears in the program.
Mainframe: Term used to describe a large computer.
Mean time between failures [MTBF]: A measure of the reliability of a computer system, equal to average operating time of equipment between failures, as calculated on a statistical basis from the known failure rates of various components of the system.
Medium scale integration: A classification of ICs [chips] based on their size as expressed by the number of circuits or logic gates they contain. An MSI IC contains 100 to 3,000 transistors.
Megabit: Approximately one million bits. Precisely 1024 K bits, 220 bits, or 1,048,576 bits.
Megabyte: Approximately one million bytes. Precisely 1024 K Bytes, 220 bytes, or 1,048,576 bytes.
Megahertz : A unit of frequency equal to one million cycles per second.
Memory : Any device or recording medium into which binary data can be stored and held, and from which the entire original data can be retrieved. The two types of memory are main; e.g., ROM, RAM, and auxiliary; e.g., tape, disk. See: storage device.
Metal-oxide semiconductor: One of two major categories of chip design [the other is bipolar]. It derives its name from its use of metal, oxide and semiconductor layers. There are several varieties of MOS technologies including PMOS, NMOS, CMOS.
Microcomputer: A term used to describe a small computer.
Minicomputer: A term used to describe a medium sized computer.
Mnemonic: A symbol chosen to assist human memory and understanding.
Modem: A functional unit that modulates and demodulates signals. One of the functions of a modem is to enable digital data to be transmitted over analog transmission facilities. The term is a contraction of modulatordemodulator.
Modulation: Converting signals from a binary-digit pattern [pulse form] to a continuous wave form [analog]. Contrast with demodulation.
Multiplexer: A device which takes information from any of several sources and places it on a single line or sends it to a single destination.
