This classification is based on their speed, size, and performance capabilities.

Explanation

The Karnaugh map (K-map) method was introduced by Maurice Karnaugh in 1953.

It is used for simplifying Boolean algebra expressions visually.

Explanation

A NAND gate gives output 0 only when all inputs are 1; otherwise, it outputs 1.

It is the inverse (NOT) of the AND gate.

Explanation

In Karnaugh Maps, 1's are grouped in powers of two (1, 2, 4, 8, etc.) horizontally or vertically to simplify Boolean expressions.

The goal is to minimize the number of terms by forming the largest possible groups of adjacent 1's.

Explanation

The AND gate performs logical multiplication, outputting 1 only when all its inputs are 1.

It is also known as a conjunction gate in digital logic.
