COMPUTER FUNDAMENTALS

Detailed explanation-1: -Parallel processing is a method in computing of running two or more processors (CPUs) to handle separate parts of an overall task. Breaking up different parts of a task among multiple processors will help reduce the amount of time to run a program.

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: -Multitasking works by time slicing-that is, allowing multiple programs to use tiny slices of the processor’s time, one after the other. PC operating systems use two basic types of multitasking: cooperative and preemptive. Cooperative multitasking was used by Windows 3.

Detailed explanation-4: -Simultaneous processing with two or more processors in one computer or two or more computers processing together. When two or more computers are used, they are tied together with a high-speed channel and share the general workload between them. If one fails, the other takes over.

Detailed explanation-5: -multiprocessing, in computing, a mode of operation in which two or more processors in a computer simultaneously process two or more different portions of the same program (set of instructions).
