IO (Input/Output)


The full form of the IO is “Input Output,” and it is pronounced “Eye-Oh.” By the way, computers are based on this fundamental idea that every input results in an output.

For example, if you run a word processor program and type a sentence on your keyboard, the text immediately appears on the screen.

Here the keyboard is an input device, and the screen is an output device. Here you can also use a printer to print text, another output device.

The computer’s CPU handles all I / O operations while sending the received data in the correct path. This path can be a video card or a hard drive, or it can also be RAM.

The ports on the outer side of the computer are usually referred to as “I / O ports” because they are the same ones that connect the input and output devices with the computer.

Software developers also use I / O to describe how a program functions, depending on what a user enters.

For example, if a user presses the space bar key in a game, where the player makes a big jump on pressing the Space Bar, in that case, the character makes a big jump on the screen.
