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.
