Which of the following statements is correct?

A. Cache memory is used for storing data and instructions used during program execution.

B. Program and data files are not required immediately by the computer system which are stored on the hard disk.

C. Program and data files rarely required are stored in RAM.

Choose the correct answer from the options given below:

Correct option is D

Statement A is correct because cache memory is a type of high-speed storage used to store frequently accessed data and instructions. Statement B is also correct because hard disks store files that are not needed immediately by the computer. Statement C is incorrect because RAM is used for storing data that is currently needed by the CPU, not for rarely required files.
Important Key Points:
1. Cache Memory - Provides high-speed access to frequently used data and instructions.
2. Hard Disk - Stores programs and files that are not immediately required.
3. RAM (Random Access Memory) - Stores data and programs currently in use, allowing quick access for processing.
Knowledge Booster:
· RAM: Used for temporary storage of data being actively processed, ensuring faster access for executing applications.
· Hard Disk: Non-volatile storage used for long-term data retention.
