Maps (a) Computer has input and output (1/0) units. The 1/0 units are the third element of the computer system besides CPU and memory. All computer systems must have efficient means to receive input and deliver output. At one time, a scanner, a mouse and a printer are sending an interrupt signals to the processor i) Determine THREE (3) techniques to be used by the processor to overcome the problem. [6 Marks] Your answer ii) From the answer in i), analyze which is the best technique to be used by the processor in the situation above. Give a reason to justify your answer. [4 Marks) Your answer (b) Interrupt Driven I/O is a way of controlling input/output activity in which a peripheral or terminal that needs to make or receive a data transfer sends a signal that causes a program interrupt to be set. A typical A4 size printed page of text contains 50 lines of 80 characters for each line. The printer can print 6 pages per minute using interrupt-driven I/O. If each character printed requires an Interrupt that takes 50 microseconds (u sec) all-in to service, how many percent of interrupt occurs will disturb the processes in the CPU?
