Which abbreviation denotes Central Processing Unit?

Which abbreviation denotes Central Processing Unit?

• A. RAM
• B. ROM
• C. CPU
• D. GPU

Answer: (C)

The main idea tested is identifying what CPU stands for and what it does in a computer. The Central Processing Unit, abbreviated as CPU, is the primary component that executes program instructions, performs calculations, and controls data flow within the system. It runs the fetch-decode-execute cycle, acting as the computer’s brain and coordinating operations between memory and peripherals. RAM and ROM are both types of memory. RAM is volatile, used for temporary data and instructions the CPU needs right now, while ROM stores firmware and is non-volatile. The GPU, or Graphics Processing Unit, is a specialized processor focused on rendering graphics and handling parallelizable tasks. These are not the central processor, which is why CPU is the correct abbreviation.
