Why is the IC important?

The invention of the IC is one of the most important innovations in modern technology. The term IC stands for integrated circuit.

An IC is a very, very tiny piece of silicon which is made up of thousands of transistors. A transistor is a device composed of semiconductor material that amplifies a signal, or open or closes a circuit. It ia an important component in modern electronics.

Integrated circuits can be produced cheaply, which means that the appliances using them, like computers, become cheaper too. Moreover, since ICs are very tiny, equipment using ICs also became  smaller have truly revolutionized the world of electronics.

Brain of the computer

The brain of computer is its CPU or central processing unit. It is made up of millions of electronic circuits. Like your brain, the CPU controls information. And tells the computer what to do.
