What does the term 'form factor' refer to in computing?

The term 'form factor' in computing primarily refers to the size, shape, and physical specifications of a computer or its components. This includes how devices are designed to fit together, as well as the overall form in which a device is packaged, which can affect its portability and the design of hardware within a system. The form factor can determine compatibility between components, such as series of motherboards, cases, and drives, which must align in size and connection types for effective operation.

Understanding form factor is essential for various aspects of computing, including hardware upgrades, the design of new systems, and ensuring that different parts can be combined in a way that is functional and efficient. This concept is particularly prominent in areas such as desktop computing, where there are specific standards for tower, mini-tower, and small form factor cases, influencing both aesthetic and functional decisions in computer design.
