Temporary storage areas in the CPU for data being processed are called which?

• A. RAM
• B. Registers
• C. Cache
• D. Buffers

Answer: (B)

Temporary storage areas in the CPU for data being processed are called registers. Registers are tiny, extremely fast storage locations built into the processor. They hold the operands for the current operation, the results of calculations, and essential control information like the program counter and status flags. Because registers sit on the CPU and connect directly to the ALU, the processor can fetch, manipulate, and store data with almost no delay, keeping the execution units working smoothly. RAM, by contrast, is the main memory outside the CPU that stores programs and data for the whole system; it’s much larger but slower to access. Cache is a small, very fast layer between the CPU and RAM that stores recently used data to speed up repeated access, but it isn’t the primary workspace for the current operation. Buffers provide temporary storage to smooth data flow between components or pipeline stages, not the immediate internal workspace for processing. So, the term that matches the description is registers.
