Answer:
D. Auxiliary memory
Read Explanation:
Auxiliary memory, also frequently referred to as secondary storage, is the non-volatile memory in a computer system. This means that it retains data even when the computer's power is turned off.
Its primary purpose is to provide long-term storage for data and programs.
Key Characteristics:
Non-volatile: Data persists even without power.
Large capacity: Typically offers significantly more storage space than primary memory (RAM).
Slower access: Data access is generally slower compared to primary memory.
Examples:
Hard Disk Drives (HDDs)
Solid State Drives (SSDs)
USB flash drives
Optical discs (CDs, DVDs, Blu-ray discs)
Relationship to Primary Memory:
Primary memory (RAM) is used for data that the CPU is actively processing. It's fast but volatile.
Auxiliary memory stores data that's not currently in use, providing a permanent storage solution.
