Question 3 (a) The concept of parallel processing came about to improve the speed of CPU performance. Parallel processing implies the simultaneous processing of information. What is the purpose of further using to provide simultaneous data processing tasks? [10 marks] (b) Explain the following under achieving Parallel processing: i. Multiplicity of functional units; ii. Parallelism and pipelining within the CPU; iii. Overlapped CPU and input/output operations; iv. The use of a hierarchical memory system; v. Balancing of subsystem bandwidths; and vi. Multiprogramming and time sharing. [10 marks] (c) Parallel computers are those which emphasise parallel processing. They can be divided into three architectural configurations, which are pipeline computers, array processors and multiprocessor system. Explain these configurations.
