copy deck
- application (Java)
- Program that runs when translated by a Java compiler.
- algorithm
- An ordered set of well-defined instructions for the solution of a problem in a finite number of steps.
- behaviour
- The way in which an object reacts to the methods applied.
- accumulator
- A storage register in the ALU that holds data temporarily while the data is processed and before it is transferred to memory.
- argument
- Value or object passed to a method when it is called.
- A-D converter
- Analog-digital converter. A device for converting analog signals to digital ones for subsequent computer processing; sometimes called "digitizer".
- applet (Java)
- Program that runs context in browser.
- balanced tree
- Tree in which the right and left subtrees of any node have heights differing by one at the most.
- analog data
- The representation and measurement of the performance or behaviour of a system by continuously variable physical entities such as currents, voltages, and so on.
- accessor methods
- Methods that do not alter the state or attributes of an object; they simply return information.
- back-up
- Second copy of a file to be used in the event of the original file being corrupted.
- base
- Basis of a notation or number system, defining a number representation system by positional representation. Binary, decimal, hexadecimal.
- abstract data structure
- A way of organizing data and its related procedures and functions.
- bar code
- Pattern of vertical lines distinguished from each other by width. It can be read by a bar code reader to provide data to a computer.
- address bus
- Pathway from memory to processing unit that carries the address in memory to and from which data is transferred.
- and
- Output of "and" is true if everything is true and false if one thing is false.
- batch processing
- Method of processing data in which transactions are collected and prepared for input to the computer for processing as a single unit.
- archive
- Represented record of data held and processed at specific time, which is held off-line for future research or for legal reasons.
- B
- Byte.
- ADSL (asymmetrical digital subscriber line)
- Technology that increases the data rate over existing telephone lines accomodating voice and digital data transfer. A special modem is required for access.
- attribute
- Element of data contained in an object; as specified within the object's class.
- array
- Arrangement of data in one or more dimensions. Aggregate that consists of data objects (identical attributes) each could be referenced by indexing.
- ALU
- Arithmetic and logic unit; part of computer that performs arithmetic operations, logic operations and related operations.
- ASCII (American Standard Code for Information Interchange)
- Primary encoding character set used in computers for textual data transfer between applications. Set uses eight bits for each code, one of these bits being a check bit to verify seven bits needed to represent one character. ASCII supports most European alphabets.
- bar code reader
- An optical reader that can read bar codes.
