Considering a computer system having multiple users and concurrent execution of multiple processes, the various processes must be protected from each other’s activities.
Protection refers to a mechanism or a way to control the access of programs, processes, or users to the resources defined by a computer system. Following are the major activities of an operating system with respect to protection −
● The OS ensures that all access to system resources is controlled.
● The OS ensures that external I/O devices are protected from invalid access attempts.
