Question

sequence of memory access while running a computer program is

Answer 1

Sequence of memory access:

CPU --> RAM (Random Access Memory) --> HARD DISK (Secondary Memory) -->RAM -->CPU Executes -->RAM  -->HARD DISK

Explanation:

Normally the CPU can fetch instructions fast from RAM than from the hard disk. Whenever the user needs to execute a program, the CPU always checks whether the instructions are available in RAM. If available it will execute and gives results faster. If not, it will first fetch instruction from Hard disk loads into RAM and then the CPU executes. As the RAM size increases, the execution becomes must faster.
