What Is an Operating System?
An operating system is the set of computer instructions, called a computer program, that
controls the allocation of computer hardware such as memory, disk devices, printers, and CD
and DVD drives, and provides the capability for you to communicate with the computer. One
of the most popular and widely used operating systems is Microsoft Windows . Microsoft
Windows XP allows you to communicate with and control your computer.
Windows XP simpliﬁ es the processes of working with documents and applications,
transferring data between documents, organizing the manner in which you interact with the
computer, and using the computer to access information on the Internet or an intranet.
Working with an operating system requires a basic knowledge of how to start the operating
system, log on and log off the computer, and identify the objects on the Windows desktop.
As a starting point, you must be familiar with the Start menu and its commands, and be able
to start an application. You will want to know how to manipulate windows as well as create
a folder, display folder contents, recognize a disk drive, and download information from
the Internet. You should be able to copy, move, rename, delete, and search for ﬁ les. If you
encounter a problem, Help and Support is available to answer any questions you may have.
