Access Time: Access time is the time from the start of one access of the storage device to the time when the next access can be started.

Accessory: An Accessory is a device attached to a host computer, but not part of it, and is more or less dependent on the host. It expands the host’s capabilities, but does not form part of the core computer architecture.
Examples are computer printers, image scanners, tape drives, microphones, loudspeakers, webcams, an digital cameras.

Active Cell: The cell that continues the value being used or modified in a spreadsheet program, and that is highlighted by the cell pointer. Also known as current cell.

Active Window: The window in Microsoft Windows with which the user may interact.

Accumulator: The computer register in which the result of an arithmetic or logic operation is formed (related to arithmetic and logic unit).

Analog Computer: A computer in which numerical data are represented by measurable physical variables, such as electrical.

Antivirus: Computer antivirus refers to a software program that can protect your computer from unwanted viruses and remove any that penetrate your computer’s defenses.

Artificial Intelligence: Artificial intelligence (AI) is the intelligence of machines and the branch of computer science that aims to create it. AI textbooks define the field as “the study and design of intelligent agents” where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success.

ASCII (American Standard Code for Information Interchange): ASCII, a code for information exchange between computers made by different companies; a string of 7 binary digits represents each character; used in most microcomputers

Abstraction: The separation of the logical properties of data or function from its implementation in a computer program.

Address: (1) A number, character, or group of characters which identifies a given device or a storage location which may contain a piece of data or a program step. (2) To refer to a device or storage location by an identifying number, character, or group of characters.

Algorithm: (1)A finite set of well-defined rules for the solution of a problem in a finite number of steps. (2) Any sequence of operations for performing a specific task.

Alphanumeric: Pertaining to a character set that contains letters, digits, and usually other characters such as punctuation marks.

Analog: Pertaining to data [signals] in the form of continuously variable [wave form] physical quantities; e.g., pressure, resistance, rotation, temperature, voltage. Contrast with digital.

Analog device: A device that operates with variables represented by continuously measured quantities such as pressures, resistances, rotations, temperatures, and voltages.

Analog-to-digital converter: Input related devices which translate an input device’s [sensor] analog signals to the corresponding digital signals needed by the computer

Android: It is linux based operating system designed primarily for touch screen mobile devices such as smartphones and tablets computers.

Application software: Software designed to fill specific needs of a user; for example, software for navigation, payroll, or process control. Contrast with support software; system software.

Architecture: The organizational structure of a system or component.

Asynchronous: Occurring without a regular time relationship, i.e., timing independent.
Attribute: The characteristics of an entity is called attributes.

Auxiliary storage: Storage device other than main memory [RAM]; e.g., disks and tapes.
