As a user, you normally interact with the operating system
through a set of commands. For example, the DOS operating system
contains commands such as COPY and RENAME for copying files and
changing the names of files, respectively.
The commands are accepted and executed by a part of the
operating system called the command processor or command line
interpreter. Graphical user interfaces allow you to enter commands by
pointing and clicking at objects that appear on the screen.
But that really doesn’t address the various ways that operating
systems make your computer work easier and more efficiently. Their
specific capacities are what make them help your computer operate as
a user-friendly device. Let’s look specifically at what an operating
system does.
