An integrated circuit is a set of electronic circuits in a single chip incorporated together to perform a specific function Integrated circuit (IC) sometimes called a chip or microchip. It is a wafer of semiconductor material (usually silicon) on which multiple transistors, capacitors and resistors are fabricated.
Devices designed to perform basic electronic functions
Discrete semiconductors perform basic functions in electronic circuits, such as rectification (diodes), amplification (transistors) and switching (transistors and thyristors). They typically have two or three terminals.
