COMPUTER SYSTEM


A computer system is defined as combination of components designed to process data and store files. A computer system consists of:
  • input devices
  • output devices
  • processor
  • storage devices
A computer system requires hardware, software and a user to fully function.

COMPUTER HARDWARE

Input devices

An input device is any hardware device that sends data to the computer, without any input devices, a computer would only be a display device and not allow users to interact with it.
Examples of input devices:
                                                 
Processor

It allows the processing of numeric data, meaning information entered in binary form, and the execution of instructions stored in memory. 
Examples:
                                               
Output devices

An output device is any peripheral device that converts machine-readable information into people-readable form such as a monitor, printer, plotter and voice output device.
Examples:

                                                  
    Storage devices

    A storage device is a hardware device capable of holding information. There are two storage devices used in computers; a primary storage device such as computer RAM and a secondary storage device such as a computer harddrive. The secondary storage could be a removableinternal, or external storage.
    Examples:
                                                 
    Peripheral devices

    peripheral is a device that is connected to a host computer, but not part of it. It is often, but not always partially or completely dependent on the host.
