Logic gate - GCSE Computer Science Definition

A logic gate is a tiny device used in computers and other electronic equipment to process information. It takes one or more electrical signals as input and produces a single output based on those inputs, following a specific set of rules. These rules are similar to simple "yes or no" questions, helping the computer make decisions. There are different types of logic gates, like AND, OR, and NOT, each performing a unique function. By combining these gates, computers can carry out complex tasks such as calculations and data processing. Logic gates are the building blocks of digital circuits, which are essential in making all modern technology work.
