Software Applications

1. (1) Application software is the general designation of computer programs for performing user tasks. Application software may have a general purpose (word processing, web browsers) or have a specific purpose (accounting, truck scheduling). Application software contrasts with (2) system software, a generic term referring to the computer programs used to start and run computer systems and networks; and (3) programming tools, such as compilers and linkers, used to translate and combine computer program source code and libraries into executable programs (programs that will belong to one of the three mentioned categories) (read more).


2. Computer software or simply software is any set of machine-readable instructions that directs a computer's processor to perform specific operations. Computer software contrasts with computer hardware, which is the physical component of computers. Computer hardware and software require each other and neither can be realistically used without the other. Using a musical analogy, hardware is like a musical instrument and software is like the notes played on that instrument.

Computer software includes computer programs, libraries and their associated documentation. The word software is also sometimes used in a more narrow sense, meaning application software only (read more).


3. Application software (an application) is a set of computer programs designed to permit the user to perform a group of coordinated functions, tasks, or activities. Application software cannot run on itself but is dependent on system software to execute. Examples of an application include a word processor, a spreadsheet design and management system, an aeronautical flight simulator, a console game, a drawing, painting, and illustrating system, or a library management system (read more).
