COMPUTER AWARENESS DAILY GLOSSARY
Qwerty: It one of the standard computer keyboard, with the character Q,W,E,R,T and Y on the top row of letters.
Quality assurance: The planned systematic activities necessary to ensure that a component, module, or system conforms to established technical requirements.
Quality control: The operational techniques and procedures used to achieve quality requirements.
Query: A request for information from a database.
Recursion: The process of defining or generating a process or data structure in terms of itself.
Register: A small, high speed memory circuit within a microprocessor that holds addresses and values of internal operations; e.g., registers keep track of the address of the instruction being executed and the data being processed. Each microprocessor has a specific number of registers depending upon its design.
Reliability:The ability of a system or component to perform its required functions under stated conditions for a specified period of time.
Risk:A measure of the probability and severity of undesired effects. Often taken as the simple product of probability and consequence.
Robustness:The degree to which a software system or component can function correctly in the presence of invalid inputs or stressful environmental conditions.
Routine:A subprogram that is called by other programs and subprograms. Note: This term is defined differently in various programming languages.
Routing:The process of choosing the best path throughout the LAN.
RS-232-C:An Electronic Industries Association (EIA) standard for connecting electronic equipment. Data is transmitted and received in serial format.
Scanner: A scanner is a piece of hardware that will examine a picture and produce a computer file that represents what it sees. A digital camera is a related device. Each has its own limitations.
Search Engine: A tool used which matches key words you enter with titles and description on the Internet. Itthen displays the matches allowing you to easily locate a subject. Similar to a card catalog, but not as efficient.Common search engines are Webcrawler, Yahoo, Alta Vista, Infoseek, Google and Lycos.
Server: (1) A computer or its software that “serves” other computers by administering network files and network operations. Three types of Internet servers are Web servers, e-mail servers, and Gopher servers. (2)A high speed computer in a network that is shared by multiple users. It holds the programs and data that are shared by all users.
Surfing: The random, aimless exploration of web pages achieved through following links that look interesting within a document
Software: Software is the set of instructions developed by programming language which tells a computer what to do.
System software: controls the overall operation of a computer. Some of the activities include managing system memory, controlling system resources, executing computer hardware functions and interfacing a user with computer hardware and applications.
Sensor: A peripheral input device which senses some variable in the system environment, such as temperature,and converts it to an electrical signal which can be further converted to a digital signal for processing by the computer.
Serial: (1) Pertaining to the sequential processing of the individual parts of a whole, such as the bits of a character or the characters of a word, using the same facilities for successive parts. (2) Term describing the transmission of data one bit at a time.
Small scale integration: A classification of ICs [chips] based on their size as expressed by the number of circuits or logic gates they contain. An SSI IC contains up to 100 transistors.
Software engineering: The application of a systematic, disciplined, quantifiable approach to the development,operation, and maintenance of software; i.e., the application of engineering to software.
Source code: Computer instructions and data definitions expressed in a form suitable for input to an assembler,compiler or other translator.
Source program: A computer program that must be compiled, assembled, or otherwise translated in order to be executed by a computer. Contrast with object program. See: source code.
Specification: A document that specifies, in a complete, precise, verifiable manner, the requirements, design,behavior,or other characteristics of a system or component, and often, the procedures for determining whether these provisions have been satisfied.
SSL/Secure Socket Layer: The leading security protocol on the Internet. When an SSL session is started,the browser sends its public key to the server so that the server can securely send a secret key to the browser.
Structured programming: Any software development technique that includes structured design and results in the development of structured programs.
Subroutine: A routine that returns control to the program or subprogram that called it. Note: This term is defined differently in various programming languages.
Synchronous: Occurring at regular, timed intervals, i.e. timing dependent.
Syntax: The structural or grammatical rules that define how symbols in a language are to be combined to form words, phrases, expressions, and other allowable constructs.
Swapping: Storing program on a disk and then transferring these programs into main storage as and when they are needed.
Synchronisation: This method ensures that the receiving end can recognise characters in order, in which the transmitting end sends them in a serial data transmission.
