Computer Hardware and Software
Computer hardware is any physical device used in or with your machine, whereas software is a collection of code installed onto your computer's hard drive. For example, the computer monitor you are using to read this text and the mouse you are using to navigate this web page are computer hardware. The Internet browser that allowed you to visit this page and the operating system that the browser is running on are considered software. All software utilizes at least one hardware device to operate. For example, a video game, which is software, uses the computer processor CPU , memory RAM , hard drive , and video card to run. Word processing software uses the computer processor, memory, and hard drive to create and save documents. Hardware is what makes a computer work.

Computer hardware includes the physical, tangible parts or components of a computer , such as the cabinet , central processing unit , monitor , keyboard , computer data storage , graphics card , sound card , speakers and motherboard. Hardware is so-termed because it is " hard " or rigid with respect to changes or modifications; whereas software is "soft" because it is easy to update or change. Intermediate between software and hardware is " firmware ", which is software that is strongly coupled to the particular hardware of a computer system and thus the most difficult to change but also among the most stable with respect to consistency of interface. The progression from levels of "hardness" to "softness" in computer systems parallels a progression of layers of abstraction in computing. 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 components. The template for all modern computers is the Von Neumann architecture , detailed in a paper by Hungarian mathematician John von Neumann.
