The keyboard controller also handles PS/2 mouse input if a PS/2 mouse port is present. Today the keyboard controller is either a unit inside a Super I/O device or is missing, having its keyboard and mouse functions handled by a USB controller and its role in controlling the A20 line becoming integrated into the chipset's northbridge and then ...
An embedded controller can have the following tasks: Receiving and processing signals from the keyboard [1] and the touchpad (including touchpad disable) Other buttons and switches (e.g., power button, laptop lid switch (received from hall sensor)) [2] Controlling access to the A20 line [3]
In computing, DirectInput is a legacy [1] Microsoft API for collecting input from a computer user, via input devices such as the mouse, keyboard, or a gamepad.It also provides a system for action mapping, which allows the user to assign specific actions within a game to the buttons and axes of the input devices.
The bidirectional IBM AT and PS/2 keyboard interface is a development of the unidirectional IBM PC keyboard interface, using the same signal lines but adding capability to send data back to the keyboard from the computer; this explains the asymmetry. [3] The interface has two main signal lines, Data and Clock.
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.

A floppy-disk controller [2] An IEEE 1284-compatible parallel port [2] (commonly used for printers) One or more 16C550-compatible serial port UARTs [2] Keyboard controller for PS/2 keyboard and/or mouse; Most Super I/O chips include some additional low-speed devices, such as: Temperature, voltage, and fan speed interface [3] [4]
[citation needed] The keyboard switch matrix is wired to its inputs, it converts the keystrokes to key codes, and, for a detached keyboard, sends the codes down a serial cable (the keyboard cord) to the main processor on the computer motherboard. This serial keyboard cable communication is only bi-directional to the extent that the computer's ...
