A peripheral device, or simply peripheral, is an auxiliary hardware device that a computer uses to transfer information externally. [1] A peripheral is a hardware component that is accessible to and controlled by a computer but is not a core component of the computer.
Examples of computer connector sockets on various laptops Ports on the back of the Apple Mac Mini (2005). A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment.

An electronic or electromechanical hardware device that is used for entering data into, and displaying data from, a computer or a computing system. touchpad. Also trackpad. A pointing device consisting of specialized surface that can translate the motion and position of a user's fingers or a stylus to a relative position on a screen. [7] TV ...
To create a nearable, one must attach an electronic device, working as both a sensor and a transmitter, to an object. Since the only limitation is the size of the device, both items and living beings can act as nearables. The most often cited examples, however, include retail and home automation environments. [8]
The most common instruction set architecture (ISA)—the interface between a computer's hardware and software—is based on the one devised by von Neumann in 1945. [17] Despite the separation of the computing unit and the I/O system in many diagrams, typically the hardware is shared, with a bit in the computing unit indicating whether it is in ...
In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to ...
Switches manage the flow of data across a network by transmitting a received network packet only to the one or more devices for which the packet is intended. Each networked device connected to a switch can be identified by its network address, allowing the switch to direct the flow of traffic maximizing the security and efficiency of the network.
USB OTG introduces the concept of a device performing both Host and Peripheral roles – whenever two USB devices are connected and one of them is a USB OTG device, they establish a communication link. The device controlling the link is called the Host, while the other is called the Peripheral.
