Correct Answer:
B. Internal memory
The computer memory primarily used for current processing tasks is known as internal memory. This term most commonly refers to RAM (Random Access Memory), which is a volatile type of memory directly accessible by the CPU. Internal memory holds data and program instructions that are actively being used by the processor. Its incredibly fast access speeds are critical for the efficient execution of programs, allowing the CPU to quickly retrieve and manipulate temporary data during operations. When a program is launched or data is being manipulated, it resides in internal memory for rapid interaction with the processor.
- Mass memory: Mass memory refers to long-term, non-volatile storage devices like hard disk drives (HDDs), solid-state drives (SSDs), or optical disks. These store data permanently but are significantly slower than internal memory and are not used for active, real-time processing by the CPU.
- PROM (Programmable Read-Only Memory): PROM is a type of non-volatile memory that can be programmed once by the user. It stores permanent instructions (like firmware or boot-up sequences) and is not designed for the dynamic, temporary storage and frequent modification required for current processing tasks. It is read-only after programming.
- None: Since "Internal memory" (or RAM) is the correct term for the type of memory used for current processing, this option is incorrect.
