What is integrated circuit?

Answer: An integrated circuit (IC) is a circuit built on a single piece of semiconductor material, typically silicon, and containing a number of electronic components, such as transistors, diodes, resistors, capacitors, and inductors. The term is also used to refer to the physical device, the die, and the package that holds the die.

The name integrated circuit means that the circuit is “integrated” on one piece of semiconductor material, usually silicon. The circuit is made up of many tiny components called transistors, which are put together to make a complete circuit. The IC can also be made up of diodes, resistors, capacitors, inductors, and other components.

The term is also used to refer to the process of building the circuit, which is called integrated circuit fabrication.

Origin

The term integrated circuit was coined in 1958 by Jack Kilby, who was awarded the Nobel Prize in Physics in 2000 for his work. The first integrated circuits were made of germanium, but silicon quickly became the material of choice.

Importance of Integrated Circuit

ICs are used in a wide variety of devices, including computers, cell phones, and other electronic equipment.

Electronic devices, such as computers, televisions, and smartphones, have many parts. Each part performs a different function. For example, a television has a power supply, a monitor, a tuner, a video processor, a sound processor, and a circuit to send signals to the television antenna.  A computer has a power supply, a motherboard, a CPU, memory, hard disk drive, video card, sound card, and many other parts. In order to make the television or computer work, all these parts have to work together.

Each part of the television or computer is connected to the other parts by wires. These wires are made of metal. If you look at the wires on the back of a computer, you can see that they are very thin. You can even see that they are made of several different colors of metal. The colors are used to identify the wires that are connected to the same part of the circuit. For example, all the red wires might be connected to the power supply, and all the green wires might be connected to the motherboard. The wires are usually very thin because the wires in the circuits of modern electronics are usually very thin.
