Computer Parts And Components

A peripheral is a device attached to a host computer but not part of it whose primary functionality is dependant upon the host, and can therefore be considered as expanding the host's capabilities, while not forming part of the system's core architecture.

Examples are printers, scanners, tape drives, microphones, speakers, webcams, and cameras.

An input device is any peripheral ( piece of computer hardware equipment ) used to provide data and control signals to an information processing system ( such as a computer ). Input and output devices make up the hardware interface between a computer as a scanner or 6DOF controller.

An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system ( such as a computer ) to the outside world.

In computing, input/output, or 1/0, refers to the communication between an information processing system ( such as a system ), and the outside world. Inputs are the signals or data sent to the system, and outputs are the signals or data sent by the system to the outside.

Examples of output devices: Speakers, Headphones, Screen ( Monitor), Printer

In computer hardware, a ' port ' serves as an interface between the computer and the other computers or peripheral devices. Physically, a port is a specialized outlet on a piece of equipment to which a plug or cable connects. Electronically, the several conductors making up the outlet provide a signal transfer between devices.
