Computer hardware is the collection of physical elements that constitute a computer system. Computer hardware refers to the physical parts or components ofa computer such as monitor, keyboard, Computer data storage, hard drivedisk, mouse, CPU (graphic cards, sound cards, memory, motherboard and chips), etc. all of which are physical objects that you can actually touch. In contrast, software is untouchable. Software exists as ideas, application, concepts, and symbols, but it has no substance. A combination of hardware and softwareforms a usable computing system.
