How processor memory unit and input output devices are connected?

They are directly connected to an electronic module inside the systems unit called a device controller. To a user, an I/O device is something outside of the system box. To a programmer, everything outside of the processor and main memory looks like an I/O devices.

How the memory and the processor can be connected?

The motherboard is a circuit board that connects the CPU to the memory and all the other hardware. The CPU sits on the motherboard (also called the logic board). Buses are circuits on the motherboard that connect the CPU to other components. The faster the bus, the faster data is communicated.

How does the microprocessor communicate with the memory and input and output device?

One communicates with a microcomputer via the I/O devices interfaced to it. Interfaces provide all input and output transfers between the microcomputer and peripherals by using an I/O bus. An I/O bus carries three types of signals: device address, data, and command. A microprocessor uses an I/O bus when it executes …

How does an input device processor and output device work together?

The CPU is responsible for executing a sequence of stored instructions called a program . This program will take inputs from an input device, process the input in some way and output the results to an output device .

What is processor & memory communication?

A bus is a collection of wires used for communication between the internal components of a computer. A data bus is used to transfer data between the memory and the CPU. The data bus is bidirectional and the address bus is unidirectional. The control bus controls both read and write operations.

Which is the connected with the processor?

The Motherboard Your computer’s brain is the CPU: that’s where all of the programming and computing happens. But its nervous system is the motherboard, which uses circuits to connect the CPU to the other pieces of hardware, including the memory, the hard drive, the CD/DVD drive, and all of your peripherals.

What is the communication between processor and memory?

A data bus is used to transfer data between the memory and the CPU. The data bus is bidirectional and the address bus is unidirectional. The control bus controls both read and write operations.

How the processor memory are communicated with I O devices *?

The IOP operates independent from CPU and transfer data between peripherals and memory. The communication between the IOP and the devices is similar to the program control method of transfer. And the communication with the memory is similar to the direct memory access method. The IOP asks for CPU through interrupt.

What is both input and output devices?

For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations.

What do you mean by input and output devices?

An input device is something you connect to a computer that sends information into the computer. An output device is something you connect to a computer that has information sent to it.

How do input and output devices communicate?

An I/O interface is required whenever the I/O device is driven by a processor. Typically a CPU communicates with devices via a bus. The interface must have the necessary logic to interpret the device address generated by the processor. Both input and output devices have a data processing rate that can vary greatly.

What is memory input or output device?

Memory, Input/output Devices. A memory is just like a human brain. It is used to store data and instructions. Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells.

What is the function of the memory in a computer?

The memory is the storage area where all the inputs are stored before processing and the outputs are stored after processing of inputs. Many devices provide input to computer and a space is required to store and queue all these inputs, before they are processed by the CPU. This is because these inputs are to be processed one by one.

What is computer processing and computer processing devices?

Computer Processing is the means by which computer programs and instructions are being executed. It is actually the process of transforming input (data) into output (information). Computer Processing devices are those devices directly responsible for the transformation of data into information.

What is the function of the CPU in a computer?

This device converts all the supplied input into output as per the instructions supplied by the user. The CPU of a computer is the device on which the speed and efficiency of the computer mainly depends on. The CPU is divided into arithmetical & logical unit (ALU) and Control Unit (CU).
