abstraction – Abstraction refers to the separation of the high-level view of an entity or an operation from the low-level details of its implementation. accessor method – A method that provides read-only access to a particular file. ACK - acknowledgement code - a signal passed between communicating processes or computers to signify acknowledgement, or receipt of response, as part of a communications protocol. actual parameter – In an invocation of a method, the values passed into a method are called the actual parameters. Actual parameters are also called arguments. Address - A numeric value that uniquely identifies a particular memory location on a computer’s main memory or a designation that uniquely identifies a computer among all others on a network. algorithm – A well-ordered collection of unambiguous and effectively computable operations that, when executed, produces a result and halts in a finite amount of time. ALU – The arithmetic/logic unit is the subsystem that performs such mathematical and logical operations as addition, subtraction, and comparison for equality. Applet - A Java program that is linked into an HTML document, then retrieved and executed using a Web browser, as opposed to a stand-alone Java application. Application Programming Interface - (API) - A set of classes that defines services for a programmer. Not a part of the language itself, but often relied on to perform even basic tasks. argument – Another name for an actual parameter arithmetic operator – An operator that performs a basic arithmetic computation, such as addition or multiplication. ARQ - Automatic repeat request algorithm is the basis for all data link control protocols in current use. It is used to correct error along the bit pipe. array – An array is a collection of memory locations that all store data of the same type. assignment – An assignment statement assigns a value to a program variable. assembly language – Assemble language is the second generation of computer languages (after machine languages) that is designed for both people as well as computers. Assembly languages created a more productive, user-oriented environment. binary – A base-two numbering system that contains two symbols (usually 0 and 1).
