Document Summary

Hardware components consist of the system unit and peripheral devices, those devices such as monitors and printers are connected to the computer. Other hardware devices, such as routers, help a computer communicate with other computers to facilitate sharing documents and other resources. Together the system unit and peripheral devices perform four main functions: 1: process inputted data, output, store the data and information. Motherboard: a circuit board that holds the cpu, ram expansion cards and other built in components. Ram: non-permanent memory it is used to store current instructions and data. Rom: stores start up instructions and is permeant memory. Cpu: the central processing unit controls all functions of the computer it is often called the brains. It can perform a large number of tasks per second. Hard drive: the main storage for your data normally permanently mounted within your computer. Drive bays: hold components of the computer such as hard drives, cd and dvd roms drives.
