Integrated Circuits
A super thin slice of semi–conducting material packed with microscopic circuit elements such as wires, transistors, capacitors, logic gates, and resistors. Bits are represented as electrical pulses that travel over these circuits.
Also called a chip, microchip Also called a chip, microchip and computer chip.and computer chip.
