Microprocessor vs. Microcomputer — What's the Difference?
By Tayyaba Rehman — Updated on September 8, 2023
A microprocessor is a silicon chip that carries out computing functions within a computer system. A microcomputer is a complete computer system that includes a microprocessor, memory, and input/output ports.

Key Differences
A microprocessor is essentially the "brain" of a computer, capable of executing a set of instructions to perform a specific task. It is an integrated circuit (IC) containing the functions of a central processing unit (CPU). In contrast, a microcomputer is a more comprehensive system, comprising not just the microprocessor but also elements like memory (RAM and ROM), storage, and input/output interfaces.
While a microprocessor is the component that performs all the operations such as addition, subtraction, multiplication, and logical operations, a microcomputer utilizes the microprocessor to execute these tasks within the framework of an entire computer system. The microprocessor is like the engine in a car, while the microcomputer is the whole car, equipped with an engine, wheels, and all the other parts that make it functional.
The microprocessor can exist independently and be integrated into a variety of devices, from washing machines to industrial robots. On the other hand, a microcomputer is generally considered an independent, standalone unit that is designed to perform general or specific computing tasks. It incorporates the microprocessor as one of its essential components but is not limited to it.
It's common to find microprocessors in a wide range of applications beyond computers, including smartphones, embedded systems, and IoT devices. Microcomputers, however, are generally thought of as personal computers (PCs), laptops, or even small servers. They are complete systems designed for end-users and capable of multiple functions, not just the processing executed by the microprocessor.
