specific tasks. Software can be categorised into two types: system software
and application software. System software includes operating systems such as
Windows, MacOS, Unix, and Linux, which manage the computer’s resources
and allow communication between hardware and software components. This
system software also includes device drivers which enable hardware components
to work with the operating system, and utility software, which is used to perform
specialised tasks.

On the other hand, application software, on the other hand, consists of programs
designed for specific tasks, such as word processors, web browsers, media
players, graphics editors, and more. Software developers create and maintain
these applications to cater for the diverse needs of users.
