Hardware, in the computer world, refers to the physical components that make up a computer system. In information technology, the hardware is the physical aspect of computers, telecommunications, and other devices. The term arose as a way to distinguish the “box” and the electronic circuitry and components of a computer from the program you put in it to make it do things. The program came to be known as the software.
