Computer hardware includes the physical parts of a computer , such as the case , [1] central processing unit CPU , monitor , mouse , keyboard , computer data storage , graphics card , sound card , speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is " hard " or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware. The template for all modern computers is the Von Neumann architecture , detailed in a paper by Hungarian mathematician John von Neumann.

Hardware refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer. Examples of hardware in a computer are the keyboard, the monitor, the mouse and the central processing unit. However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing tower.
