Software vs. Hardware — What's the Difference?

Software is a collection of instructions and data that tell a computer how to work. This is in contrast to physical hardware, from which the system is built and actually performs the work.

Metal goods and utensils such as locks, tools, and cutlery.

The programs, routines, and symbolic languages that control the functioning of the hardware and direct its operation.

(Computers) A computer and the associated physical equipment directly involved in the performance of data-processing or communications functions.

(computing) Encoded computer instructions, usually modifiable (unless stored in some form of unalterable memory such as ROM).

Machines and other physical equipment directly involved in performing an industrial, technological, or military function.

(military) The human beings involved in warfare, as opposed to hardware such as weapons and vehicles.

(Informal) Weapons, especially military weapons.

(computer science) written programs or procedures or rules and associated documentation pertaining to the operation of a computer system and that are stored in read/write memory;

Fixtures, equipment, tools and devices used for general-purpose construction and repair of a structure or object. Also such equipment as sold as stock by a store of the same name, e.g. hardware store.

The sum of all the physical objects, such as the electrical, mechanical, and electronic devices which comprise a computer system; as, the typical PC hardware suite consists of a mainboard and a number of peripherals such as hard drives and speakers, connected by adapter cards, but the input and output from users occurs mostly through the keyboard and monitor; contrasted with software, the programs executed by the computer.

The weapons, transport, and other physical objects used in conducting a war.

Weapons, especially handguns, carried on the person; as, check your hardware at the door before entering.
