The computer will be of no use unless it is able to communicate with the outside world. Input/Output devices are required for users to communicate with the computer. In simple terms, input devices bring information INTO the computer and output devices bring information OUT of a computer system. These input/output
I/O controller: UART (Universal Asynchronous. Receiver Transmitter) or ACIA (Asynchronous. Communications Interface Adapter). § Used for modems and other serial devices. § Physical Implementation: – 2 signal wires (one for each direction) + ground reference. Tx data wire (CPU to I/O device). Rx data wire (I/O device to

In many computers the buses are made accessible using connectors into which cards are slotted. There are two major design approaches to bus timing. Synchronous design requires devices to
When I/O devices and the memory share the same address space, the arrangement is called memory- mapped I/O. ? With memory-mapped I/O, any machine instruction that can access memory can be used to transfer data to or from an I/O device. ? Most computer systems use memory-mapped I/O. ? Some processors
Accessing I/O Devices. • Most modern computers use single bus arrangement for connecting I/O devices to CPU & Memory. • The bus enables all the devices connected to it to exchange information. • Bus consists of 3 set of lines : Address, Data, Control. • Processor places a particular address (unique for an. I/O Dev.)

INPUT OUTPUT DEVICES. A computer system needs to communicate with its external environment its user). The Input/output devices provide this capability to a computer system. they are also known as peripheral devices, because they surround a computer's cpu and memory. • INPUT DEVICE. • CPU & memory.
I/O Devices. Before delving into the main content of this part of the book (on persis- tence), we first introduce the concept of an input/output (I/O) device and show how the operating system might interact with such an entity. I/O is quite critical to computer systems, of course; imagine a program without any input (it produces the
