Introduction to hardware

Computer hardware is the assembly of physical elements that establish a computer system. Computer hardware mentions to the physical parts or mechanisms of a computer such as monitor, keyboard, computer data storage, hard drive disk, mouse, system unit (graphic cards, sound cards, memory, motherboard and chips), etc. All of which are physical objects that you can actually touch. In difference, software is untouchable. Software exists as ideas, application, concepts, and symbols, but it has no material. An arrangement of hardware and software preparations an usable computing system.
