What is an Integer

An integer in computer terminology refers to a data type used to represent whole numbers, both positive and negative, without any fractional or decimal components. Integers are essential in programming and computing, as they are used to perform calculations, control loops, and represent data that can only take on discrete values.

In most programming languages, integers are stored in binary form and have specific size limits based on the system architecture, typically 32-bit or 64-bit. Integers are different from floating-point numbers, which include decimals.
