Today’s technology has been evolved into stand-alone systems which can do all necessary processes by themselves
without any additional hardware. Advance microcontrollers have become microcomputers that are also known as single board
computers. These systems take their power from powerful microcontrollers. These microcontrollers have many integrated
circuits on board so they can achieve many different processes by themselves. They are being used in many applications from
powerful industrial devices to simple home appliances. In today’s market, there are many different microcontrollers with
different structure and capabilities.
