integrated circuit (IC)
An integrated circuit (IC) is a combination of electronic components, such as transistors, capacitors, and resistors. An IC is designed to fulfill some logical function and can be built to be a timer, counter, a bank of computer memory,
or even a microprocessor.

The basic building block of an IC is a logic gate. A logic gate performs the Boolean algebra AND operation by testing two input signals (each stored in a transistor). If both are positive (representing true or 1), it sets the signal of a result value to positive. Otherwise, the value is set to negative (representing false or 0).
