 An operating system (OS) is system software that
enables the computer hardware to communicate and
operate with the application software.
 Manufacturers of peripheral devices provide programs
called drivers that the operating system uses to
communicate with various hardware devices.

 An operating system also manages resources for
applications.
 Another way an operating system helps applications is
by performing system and file maintenance tasks.
 The way an operating system stores files on disk is
called a file system.

 In many business, personal, and educational settings, it is
necessary to share files across operating system platforms.
 One type of hardware solution is an emulation card that
allows the computer to run a program that was designed
for a different operating system.

 The tasks you are allowed to perform are defined by your user
rights, set by the system administrator to protect the computer’s
security.
 The system administrator is a user who has an administrator
account.
 The administrator account provides unrestricted access to make
systemwide changes to the computer, such as system
modifications, installing software, or changing network settings.
 The administrator can grant administrative rights to other users.
