Question

1 Explain the process of how the memory works with theprocessor​

Answer 1

Answer:

As every processor works on same stages i.e. fetch , decode , execute.

Most of the computers executes ONE instruction at a time. But speed is very fast .

So let's move to memory

The fastest memory is cache (registers)

Then RAM , then hard disk.

Before an instruction can be executed, program instructions and data must be placed into memory from an input device or a secondary storage device .

Then

1)The control unit fetches (gets) the instruction from memory.

2)The control unit decodes the instruction (decides what it means) and directs that the necessary data be moved from memory to the arithmetic/logic unit. These first two steps together are called instruction time, or I-time.

3)The arithmetic/logic unit executes the arithmetic or logical instruction. That is, the ALU is given control and performs the actual operation on the data.

4)Thc arithmetic/logic unit stores the result of this operation in memory or in a register. Steps 3 and 4 together are called execution time, or E-time.
