what is meant by input and output devices
Input/output I/O devices are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations.
Docking station In computing and video gaming, a docking station or port replicator or dock provides a simplified way of "plugging-in" an electronic device such as the tablet-like hybrid video game console, the Nintendo Switch and laptop computer to common peripherals. Because a wide range of dockable devices—from mobile telephones to wireless mice—have different connectors, power signaling, and uses, docks are not standardized and are therefore often designed with a specific make and model of a device in mind.[citation needed]
