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

For example, if you are running a word processor program and type a sentence in your keyboard , then 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, which is another output device.

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

The ports on the external 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 actually makes a big jump on the screen.
