Integrated Circuits are small black chips are found in computers, consumer electronics and network equipment. These are used as an oscillator, timer, amplifier, microprocessor, micro controller and computer memory. These chips are made of silicon and has the ability to hold hundred of millions of transistors, capacitors and resistors. These Integrated Circuits are heart and brain of modern electronics. These small chips have ability to perform calculations and store data by using analog or digital technology. These microchips  are the keystone in most of the circuits.
