FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Parallel execution is the ability to apply multiple CPU and I/O resources to the execution of a single database operation. It dramatically reduces response time for data-intensive operations on large databases typically associated with decision support systems (DSS) and data warehouses.

Detailed explanation-2: -Parallel computing refers to the process of breaking down larger problems into smaller, independent, often similar parts that can be executed simultaneously by multiple processors communicating via shared memory, the results of which are combined upon completion as part of an overall algorithm.

Detailed explanation-3: -Parallel computing uses multiple computer cores to attack several operations at once. Unlike serial computing, parallel architecture can break down a job into its component parts and multi-task them. Parallel computer systems are well suited to modeling and simulating real-world phenomena.

Detailed explanation-4: -Which of the following is true about parallel computing performance? Computations use multiple processors. There is an increase in speed. The increase in speed is loosely tied to the number of processor or computers used.
