FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time. The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information.

Detailed explanation-2: -multitasking, the running of multiple programs (sets of instructions) in one computer at the same time. Multitasking is used to keep all of a computer’s resources at work as much of the time as possible.

Detailed explanation-3: -Virtualization software-programs that allow you to run multiple operating systems simultaneously on a single computer-allows you to do just that. Using virtualization software, you can run multiple operating systems on one physical machine.

Detailed explanation-4: -Mainframe Computers: Large organizations use mainframes for highly critical applications. Most of the mainframe computers have the capacity to host multiple operating systems and operate as a number of virtual machines and can thus substitute for several small servers.

Detailed explanation-5: -Multitasking is the ability of the operating system to run more than one application at a time. A multitasking operating system (also called a multiprocessing operating system) supports two or more active processes simultaneously.
