What is the difference between microcontroller and microprocessor?

Microprocessor is the device which contains no RAM, ROM and no I/O ports on the same chip itself  and it is also known as the general purpose microprocessor . Some important microprocessors are Intel's x86 family (8086, 80286, 80386, 80486 and the pentium ). Whereas a microcontroller has a CPU (microprocessor) in additiion  it  also have RAM , ROM , and I/O ports on the same chip. In other  words the processor , RAM , ROM , I/O ports and timer  are all embedded together on the one chip.
The microcontroller is widely used in many devices for many diffferent applications. Some of the important microcontroller are  8051, PIC . AVR
