System software controls a computer and provides the environment for users to run application software. It is a collection of programs, with different functions and purposes, mainly the Operating System (OS) that controls a complete computer. Device drivers and utilities are also included in the system software. In contrast to this, computer users typically run application software to perform tasks, play games, listen to music, and make use of a computer.
A computer’s system software allows users to run applications.
operational systems
Although it has many components, the system software on a computer is generally based on the operating system installed on it. There are many different companies that make operating systems, although some of the more prominent ones include Microsoft®, Apple®, and groups that work with open formats like Linux®. These companies produce and release various versions over time, including Windows XP®, Apple Mac OS X®, and Ubuntu®. Much of the debate revolves around the question of which system is superior, and often comes down to the personal preferences and individual needs of a computer user.
System software often includes diagnostic and troubleshooting tools.
Run multiple operating systems
Some computers can run two different types of system software; such as Mac OS X® and a version of Windows®. Users often employ one of two different methods to run more than one operating system at the same time. One way is through software that allows the user to choose the preferred operating system to boot into. The other is through desktop software run by a user, which allows access to two operating systems simultaneously on one machine.
system utilities
The utilities include a variety of specialized programs that can be applied to various applications. Basic utilities include diagnostic and troubleshooting software that can scan a system or other program for errors and missing files. Additional utilities include data backup programs, file compression software, and tools used to completely uninstall other programs.
device drivers
Device drivers are necessary for all peripherals and devices connected to a computer, from the mouse and keyboard to the printer. This type of system software allows the operating system to effectively identify and communicate with hardware attached to a machine. The operating system may include device drivers for basic components like a mouse and keyboard, while peripheral manufacturers often provide driver disks for users to install with their hardware.
Other types of programs
System software differs from application software in a few important ways. First, it is necessary, while most computer users consider any particular application to be optional. It is also comprehensive, as no computer needs to have more than one version of any type of system software at any given time. Applications, on the other hand, are often placed on a computer in large numbers, some providing similar functionality with only minor differences. Also, system software is self-contained and does not require any application software to run, while applications cannot run without proper operating system and drivers.
Device drivers for computer mice are required.
