Logic gates are fundamental components in digital electronics, used to perform logical operations on one or more binary inputs to produce a single binary output. They are the building blocks of digital circuits and systems, such as computers, communication systems, and more1.
Types of Logic Gates
AND Gate
The AND gate performs logical multiplication. It produces a high output (1) only when all its inputs are high (1). The Boolean expression for a two-input AND gate is:
Z = A.BTruth Table:
A | B | A AND B0 | 0 | 00 | 1 | 01 | 0 | 01 | 1 | 1OR Gate
The OR gate performs logical addition. It produces a high output (1) if at least one of its inputs is high (1). The Boolean expression for a two-input OR gate is:
Z = A + BTruth Table:
A | B | A OR B0 | 0 | 00 | 1 | 11 | 0 | 11 | 1 | 1NOT Gate
The NOT gate, also known as an inverter, produces the complement of its input. If the input is high (1), the output is low (0), and vice versa. The Boolean expression for a NOT gate is:
Z = A'Truth Table:

Logic gate - Wikipedia
Charles Sanders Peirce (during 1880–1881) showed that NOR gates alone (or alternatively NAND gates alone) can be used to reproduce the functions of all the other logic gates, but his work on it was unpublished until 1933. The first published proof was by Henry M. Sheffer in 1913, so the NAND logical operation is sometimes called Sheffer stroke; the logical NOR is sometimes called Peirce's arrow. Consequently, these gates are sometimes called universal logic gates.
