A microcontroller differs from a microprocessor in many ways. The first and most important difference is its functionality. In order that themicroprocessor may be used, other components such as memory must be added to it. Even though the microprocessors are considered to bepowerful computing machines, their weak point is that they are not adjusted to communicating to peripheral equipment.Simply, In order to communicate with peripheral environment, the microprocessor must use specialized circuits added as external chips. In shortmicroprocessors are the pure heart of the computers. This is how it was in the beginning and remains the same today.
