State and explain two parameters used in classifying microprocessors.

a)Clock Speed.
Every Microprocessor has a clock that drives its operation. Clock speed is the speed at which the processor runs.
Microprocessor speed refers to its Clock speed, which is measured in Megahertz (MHz – 1 million cycles per second).
The Clock speed varies from one processor to another. Microprocessors with faster clocks perform operations much faster compared to those with slower clocks. Therefore, the speed of a microprocessor gives its power – the higher the speed, the more powerful the microprocessor.
Note. The speed at which a computer can process data is also affected by the speed at which the memory can work.

b)Bus Width.
The size of the Data Bus determines the Bus Width of a microprocessor. It indicates the moving capability of information of the chip.
Higher Bus widths provide higher computer performance. For example, fetching a 16-bit instruction from memory using a Data bus width of 16 bits would require a single fetch operation, whereas an 8-bit Data bus would require 2 cycles to fetch the same instruction; hence slowing the execution of the instruction.
