Determine different applications of operating system regarding system performance and system stability?
In any computer, the operating system: Controls the backing store and peripherals such as scanners and printers. Deals with the transfer of programs in and out of memory. Organizes the use of memory between programs. Organizes processing time between programs and users. Maintains security and access rights of users. Deals with errors and user instructions.
