# Parameter vs. Perimeter: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 10, 2023
A parameter is a variable or factor that defines a system's characteristics or behavior, while a perimeter is the continuous line forming the boundary of a closed geometric figure.

## Key Differences

Parameter refers to a variable or an element that determines the behavior, limits, or conditions of a function or system in mathematics, statistics, or computer programming. It's a guiding or defining factor. In contrast, perimeter is a term used in geometry to describe the total length of the edges of a two-dimensional shape.

In the context of a mathematical function, a parameter is a variable that is part of the function's definition and influences its output. On the other hand, a perimeter is a measurable physical property of a shape, representing the distance around the shape.

In computer programming or system design, a parameter is a value or characteristic that is passed to a function or system, defining its operation or the scope of its activity. Meanwhile, the concept of perimeter is often used metaphorically in security systems, referring to the boundary that separates the secure internal network from the outside world.

Parameters are essential in scientific experiments as well, where they represent variables that can be adjusted or measured during the experiment. In contrast, in architecture or construction, the perimeter of a building or room refers to the sum of the lengths of all its sides.

A parameter can be an abstract concept, not necessarily physical, and is used in a variety of fields to denote a characteristic or factor that affects outcomes. Perimeter, however, is always a concrete measurement and is specifically a geometric term related to physical shapes.
