Input instruction is used to transfer data from i o device to cpu, store instruction is used to transfer data from cpu to memory and output instruction is used to transfer data from cpu to i o device.
Unit 5 Input Output Organization Pdf Input Output Central Consider a simple example of i o operations involving a keyboard and a display device in a computer system. the four registers shown below are used in the data transfer operations. These come from input—output (i o) devices, from a timing device, from a circuit monitoring the power supply, or from any other external source. ex: i o device requesting transfer of data, i o device finished transfer of data, elapsed time of an event, or power failure. Chapter 5 discusses input output (i o) modules, emphasizing the need for these modules to interface between various peripheral devices and the processor due to differences in data rates and formats. Other input and output devices encountered in computer systems are digital incremental plotters, optical and magnetic character readers, analog to digital converters, and various data acquisition equipment.

Notes of coa unit 5 coa organization input output: peripheral devices, interface, ports, interrupts: interrupt hardware, types ofinterrupts and exceptions. Input output: peripheral devices, i o interface, i o ports, interrupts: interrupt hardware, types of interrupts and exceptions. modes of data transfer: programmed i o, interrupt initiated i o and direct memory access., i o channels and processors. Input, memory, arithmetic and logic, output, and control units, as shown in figure 1.1. the input unit accepts coded information from human operators u. ing devices such as keyboards, or from other computers over digital communication lines. the information received is stored in the computer‟s memo. Input output interface input output interface provides a method for transferring information between internal storage and external i o devices. peripherals connected to a computer need special communication links for interfacing them with the central processing unit.
