How does the CPU interact with input devices?

Answer 1

On the most basic level, the keyboard is a collection of momentary switches. Each time you press a key down, you close one of these contacts. When you lift the key, the contact opens again. The electrical contacts are read and interpreted in the keyboard. Circuit logic within then determines which key was pressed or released. Finally, translation logic converts this information into a useable format which is then sent down the keyboard's wire (and/or wireless channel) and into the keyboard's connected bus. While in the old days keyboards had a dedicated low-bandwidth bus for this purpose, most keyboards these day employ the Universal Serial Bus, which defines how keyboards are supposed to operate. Either way, the computer receives the information from the keyboard through the bus which tells it what you just typed.

Answer 2

The CPU doesn't. Keyboard commands go through the motherboard and are relayed to the operating system. The OS handles input and translates it into commands which are then sent to running processes. Eventually the keyboard input is translated into assembly instructions which can be executed by the CPU.

Answer 3

Input, anything that let you put data in is input device that gives you data from computer, like a monitor, speaker, or a printer are output device

Answer 4

A computer gets an input through a keyboard.

Answer 5

CPU is the brain of the computer. If you want a input device (hard drive, USB) it processes it, and access all the files.

Answer 6

through motherboard
