System
software is any program (hat controls the computer’s hardware or that can be
used to maintain the computer in some way so that it runs more efficiently.
There are three basic types of system software:
» An
operating system tells the computer how to use its own components. Examples of
operating systems include Windows, the Macintosh Operating System, and Linux.
An operating system is essential for any computer; because it acts as an
interpreter between the hardware, application programs, and the use when a
program wants the hardware to do something, it communicates through the
operating system. Similarly, when you want the hardware to do something (such
as copying or printing a file), your request is handled by the operating
system.
» A
network operating system allows computers to communicate and share data across
a network while controlling network operations and overseeing the network’s
security.
» A
utility is a program that makes the computer system easier to use or performs
highly specialized functions. Utilities arc used to manage disks, troubleshoot
hardware problems, and perform other tasks that the operating system itself may
not be able to do.
