MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Algorithms in which several operations may be executed simultaneously are referred to as parallel algorithms. In general, a parallel algorithm can be defined as a set of processes or tasks that may be executed simultaneously and may communicate with each other in order to solve a given problem.

Detailed explanation-2: -A parallel algorithm is an algorithm that can execute several instructions simultaneously on different processing devices and then combine all the individual outputs to produce the final result.

Detailed explanation-3: -First, the addition of more processor cores doesn’t automatically improve computer performance. The OS and applications must direct software program instructions to recognize and use the multiple cores. This must be done in parallel, using various threads to different cores within the processor package.

Detailed explanation-4: -Parallel Computing is the study, design, and implementation of algorithms in a way as to make use of multiple processors to solve a problem. The primary purpose is the solve a problem faster or a bigger problem in the same amount of time by using more processors to share the work.
