System software

System software is computer software designed to operate the computer hardware and to provide a platform for running application software.[1][2]
The most basic types of system software are:
In some publications, the term system software is also used to designate software development tools (like a compiler, linker or debugger).[3]
Computer purchasers seldom buy a computer primarily because of its system software (But purchasers of devices like mobile phones because of there system software, as is the case with the iPhone, as the system software of such devices is difficult for the end-user to modify). Rather, system software serves as a useful (even necessary) level of infrastructure code, generally built-in or pre-installed.
In contrast to system software, software that allows users to do things like create text documents, play games, listen to music, or surf the web is called application software.[4]

[edit] Types of system software programs

System software helps use the operating system and computer system. It includes diagnostic tools, compilers, servers, windowing systems, utilities, language translator, data communication programs, database systems and more. The purpose of system software is to insulate the applications programmer as much as possible from the complexity and specific details of the particular computer being used, especially memory and other hardware features, and such accessory devices as communications, printers, readers, displays, keyboards, etc.
Specific kinds of system software include:
If system software is stored on non-volatile memory such as integrated circuits, it is usually termed firmware.
