Systems Software
Introduction
To be able to use a computer, we need software – a computer without any software is like an
empty shell and is totally useless.
We can group software into two categories:
Systems Software
o This is software required to start the computer and do general household jobs like
copying files, renaming files, providing access to the networks and provide service to
applications software.
Applications Software
o This is software like Microsoft Word, Internet Explorer that allows the user of the
computer to do some specific tasks, word processing and surfing the web for example
