the computer what to do.
Software can be categorized into two (2),
system software
application software

5. Systems Software
 It is the set of programs that lies between
applications software and the hardware devices.
All computers, regardless of size, require the
operating systems software.
 As soon as your personal computer is turned on,
the operating systems software is loaded into the
memory (RAM) in order to use your computer
devices and other software.

6. Thus a typical example of the system

an operating system called DOS, (Disk
Operating System).
