    Computer memory is categorized into primary and secondary memory:

    1. Primary Memory:

      • RAM (Random Access Memory): Volatile memory used for temporary data storage while a computer is on.
      • ROM (Read-Only Memory): Non-volatile memory storing essential system instructions; not writable.

    2. Secondary Memory:

      • Hard Drives (HDD): Magnetic storage with large capacity for long-term data storage.
      • Solid State Drives (SSD): Faster, flash-based storage with no moving parts.
      • Optical Discs (CD/DVD/Blu-ray): Laser-read discs for data storage and media distribution.
      • USB Flash Drives: Portable, flash-based storage for easy data transfer.
