RAM

ROM

Flash Memory

Cache Memory

- RAM (Random Access Memory):

- This is the main memory used by computers for temporary data storage.

- It is fast but slower than cache memory.

- Acts as the workspace for running programs and data.

- ROM (Read Only Memory):

- Used to store firmware or permanent instructions for the computer.

- Cannot be written to easily by normal programs.

- Not used as a buffer for CPU operations.

- Flash Memory:

- A type of non-volatile storage, often used in USB drives and SSDs.

- Much slower compared to RAM and cache memory.

- Cache Memory:

- Extremely fast and acts as a high-speed buffer between the CPU and main memory (RAM).

- Stores frequently accessed data and instructions to speed up processing.

- Vital for reducing the CPU’s average memory access time.
