What is a microprocessor? Explain the difference between microcontrollers and microprocessors.

Question

Krishnapriya Rajeev · Answer

A microprocessor is an electronic component that acts as the central processing unit (CPU) of a computer or other electronic device. It does not typically include other components like memory and I/O ports. Instead, it is used in conjunction with other components such as memory chips, input devices, and output devices to create a complete computer system. It receives instructions from memory, processes them, and sends the results back to memory.

Microcontrollers and microprocessors are two types of electronic components that perform similar functions but have some key differences. They are as follows:

Microprocessors	Microcontrollers
Designed for general-purpose computations.	A special form of a microprocessor.
Require external components such as memory and input/output interfaces.	Have integrated memory, input/output interfaces, and timers.
Used in more complex systems that require higher performance and versatility.	Used in simple systems that require low power consumption and low cost.
High power consumption.	Low power consumption.
It has high processing power.	Its microprocessor has less processing power.
It follows Von Neumann's architecture.	It follows Harvard's architecture.
It requires an external bus.	It has an internal controlling bus.
System cost is high.	System cost is low.
