Embedded systems

• What are Microcontrollers and their types?
  Microcontrollers are broadly utilized in Embedded System products. An Embedded product uses the microprocessor (or microcontroller) to do a single task only. A printer is an instance of embedded system as the processor in it performs single task only namely receiving the data and printing it.
