Show answer & explanation

Correct answer: C

Answer: microprocessor does not contain I/O devices.

Explanation: A microprocessor is a single integrated circuit that implements the central processing unit (CPU). It provides the processing core but does not include the input/output devices or memory needed to form a working computer system.

  • Microprocessor: CPU only (requires external memory and I/O peripherals).

  • Microcomputer: a complete system built around a processor that includes memory and I/O devices, allowing it to operate standalone.

  • Note: Word size varies by processor design and is not the main factor distinguishing a microprocessor from a microcomputer.

Summary: The key distinction is that a microprocessor is just the processing chip without built-in I/O devices, whereas a microcomputer is a complete system that includes those I/O components.
