Microprocessor vs Microcontroller

A list of differences between Microprocessor and Microcontroller are given below.

S.No	Microprocessor	Microcontroller
1	Microprocessor acts as a heart of computer system.	Microcontroller acts as a heart of embedded system.
2	It is a processor in which memory and I/O output component is connected externally.	It is a controlling device in which memory and I/O output component is present internally.
3	Since memory and I/O output is to be connected externally. Therefore the circuit is more complex.	Since on chip memory and I/O output component is available. Therefore the circuit is less complex.
4	It cannot be used in compact system. Therefore microprocessor is inefficient.	It can be used in compact system. Therefore microcontroller is more efficient.
5	Microprocessor has less number of registers. Therefore most of the operations are memory based.	Microcontroller has more number of registers. Therefore a program is easier to write.
6	A microprocessor having a zero status flag.	A microcontroller has no zero flag.
7	It is mainly used in personal computers.	It is mainly used in washing machines, air conditioners etc.
