Answer:

(c) 16

Explanation:

An opcode is the short form for operation code which is also called instruction code. This code forms part of the instructions (instruction set) executed by the computer and it tells the computer the actual operation to be performed. The size of the opcode is the number of bits occupied by it. It is related to the instruction set size as follows;

2ˣ = I   ----------------(i)

Where;

x = opcode size or bit

I = maximum or total number of instructions allowed

From the question,

x = 4 bits.

Substitute this value into equation (i) as follows;

2⁴ = I

I = 16.

Therefore, the maximum number of instructions allowed in your instruction set or your PROM - Programmable read-only memory - is 16

lozanna [386]

Answer:

Increased processor speed and multi core technologies.

Explanation:

The development of processors over the years is overwhelmingly fast. The CPU use to be cumbersome, expensive and computational speed was moderate.

As it evolves, the CPU was minimized to give rise to microprocessors.

Microprocessors are very fast, running millions of processes on its core. The multiple core processors helped to increase the speed of these processors.

When there are more than one core in a processor (dual, quad or octal core), it processes data in parallel reducing the time of execution compared to a one core processor.

A company having computers with single core would need to upgrade to a new computer with multi core processor to promote speed in data processing.
