Difference Between RAM and ROM?

In the world of computers, memory plays a crucial role. This storage can be divided into two main types: Primary Memory and Secondary Memory.

What is Primary Memory?

Primary memory (main memory) is where data and instructions are accessed directly by the CPU. It is short-term memory (volatile). Examples include RAM (Random Access Memory) and cache memory. It is fast but loses data when power is off.

What is Secondary Memory?

Secondary memory is long-term storage. It retains data even when the computer is turned off (non-volatile). Examples include Hard Disk Drives (HDDs), Solid State Drives (SSDs), USB drives, and ROM (Read Only Memory). It allows for permanent data storage.
