System Software and Application Software
Computer software is a general term use to describe “a collection of computer programs, procedures and documentation that perform some tasks on a computer system”. The term includes application software such as word processors which perform productive tasks for user, system software such as operation system which interface with hardware to provide the necessary services for application software, and middleware which controls and co-ordinates distribute system.
System software is any “computer software which manages and controls computer hardware so that application software can perform a task”. Operating systems, such as Microsoft Windows, Mac OS or Linux, are prominent example of system software.
Application software is a subclass of computer software that “employs the capabilities of a computer directly and thoroughly (completely) to a task that the user wishes to perform”. In this context the term application refers to both the application software and its implementation. Typical examples software applications are word processors, spreadsheet, and media players.
Operating system: “the software component of a computer system that is responsible for the management and coordination of activities and the sharing of the resourced of the computer”. The operating system (OS) acts as host for application programs that are run on the machine.
