The hardware components of an information system are the physical items that belong to that system—the things that you are able to see and touch. Hardware components encompass different types of hardware. First is the processor and associated memory, referred to as the computer by most end users. Professionals might call this a tower or, in the case of larger processor banks, a server.
Information systems hardware also encompasses peripheral devices, such as the mouse, keyboard, printer, monitor, and other similar attachments to the system. These usually either take input from, or give output to, the end user. Input devices can also take input from other systems, so long as the source is outside the processor or computer in question.
