Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

Question

Processors had 2.5% of the work to do. Instead, show the impact on speed-up if
one processor's load is higher than all the rest. Calculate at twice the load (5%)
and five times the load (12.5%) for that hardest working processor. How well
utilized are the rest of the processors?

Explain what you mean by "pipelining" in the context of improving processor speed, and then determine how many cycles it will take to run five instructions assuming each part of the machine requires one cycle. First, we'll look at the situation a) without pipelining and b) with pipelining. There are four ways to do this: a, b, c, and d, all of which include pipelining.
