What is the central processing unit commonly made from a single integrated circuit?

• A. Central Processing Unit
• B. Integrated Circuit
• C. Microprocessor
• D. Central Processor

Answer: (C)

A single integrated circuit version of the CPU is called a microprocessor. A microprocessor combines the essential parts that run programs—the arithmetic logic unit, control unit, and the necessary registers—onto one silicon chip, making the entire processor a single-chip device. That compact, on-chip implementation is what defines a microprocessor and is why it’s the correct answer here. The other terms describe related ideas but don’t specify this one-chip construction. The central processing unit is the function—the part that executes instructions—but it isn’t by itself defined as a single chip. An integrated circuit is the fabrication technology that allows circuits on one chip, not the device that actually runs software. A central processor is another label for the CPU, but it doesn’t convey the single-chip implementation.
