WebSome common I/O devices are mouse, keyboard, touchpad, USB devices, Bit-mapped screen, LED, On/off switch, network connections, audio I/O, printers etc. An I/O system takes an I/O request and sends it to the physical device. It then sends the response from the device to the application. There are two types of I/O devices: WebInterrupt & I/O: 11 1: TITLE Keyboard interrupt service program KEYBOARD.ASM 2: COMMENT 3: Objective: To demonstrate how the keyboard works. 4: Input: Key strokes from the keyboard. Only left 5: and right shift keys are recognized. 6: ESC key restores the original keyboard ISR
