Computer system hardware is made up of multiple components. These components are devices that can be classed as input, storage, output, and processing. Input devices are the components of hardware that allow for communication to flow between the end-user and the computer. Output devices are the components that allow for the communication to flow between the end-user and the computer. The main processing components are the central processing unit (CPU), the bus, the basic input/output system (BIOS), the complementary metal-oxide semiconductor (CMOS) and the controller. There are two types of storage. Primary storage or random access memory (RAM) is the memory that the central processing unit, or CPU, uses to go directly to a byte of information instead of having to search sequentially. Secondary storage is archived. (Elchouemi, 2006)
There are different devices for input, output, and storage due to the many different tasks computers are expected to accomplish. Different devices were created or adapted to suit different needs, systems, and user preferences. Accuracy, quality, and convenience are all factors in choosing hardware.
