Devices for communication between computers, such as modems and network cards, typically perform both input and output operations. Any interaction with the system by an interactor is an input and the reaction the system responds is called the output. The designation of a device as either input or output depends on perspective.
A computer keyboard is a peripheral input device modeled after the typewriter keyboard [1] [2] which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter -style keyboards have been the main input method for computers since ...

In the HID protocol, there are 2 entities: the "host" and the "device". The device is the entity that directly interacts with a human, such as a keyboard or mouse. The host communicates with the device and receives input data from the device on actions performed by the human. Output data flows from the host to the device and then to the human.
A rate-control input device (e.g., trackpoint, joystick) changes the speed and direction of the movement of the on-screen pointer. translation vs. rotation; Another classification is the differentiation between whether the device is physically translated or rotated. degrees of freedom; Different pointing devices have different degrees of ...
