A computer is a machine that carries out a sequence of instructions. While most people think of computers as machines which do information processing only, such as Laptops and Servers, there is also a category of computers called "Embedded Computers" or Embedded Systems. In Embedded Systems, the computer is used for a very specific purpose, which is typically to control the device which it is a part of. Embedded Systems span a wide range, from small medical devices such as hearing aids, blood pressure sensors, pace makers to household appliances such as Washer & dryers, Refridgerators, Coffee makers, to automotive, industrial and airospace uses.
