Answer 3

An operating system (OS) is a software program that manages the hardware and software resources of a computer. The OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files.
Every action on a computer, be it background services or applications, is run inside a process. Older operating systems such as DOS could only run one process at a time. Modern operating systems are able to run many at once (multi-tasking). Process management is an operating system's way of dealing with running multiple processes. Since most computers contain one processor with one core, multi-tasking is accomplished by simply switching processes quickly. As a user runs more processes, all timeshares become smaller. On many systems, this can eventually lead to problems such as skipping of audio or jittery mouse movement. Process management involves the computation and distribution of "timeshares". Most operating systems allow a process to be assigned a process priority which impacts its timeshare.

Pressing CTRL+ALT+DEL brings up the process manager on Windows 95, Windows 98, and Windows XP as well as KDE for Linux.
