What is I/O?
Input/Output
The process by which a computer system receives data from and sends data to the outside world.
Overview
I/O is an I/O process when a computer receives text from the keyboard, downloads data from the internet, or prints something to the screen. The system establishes all kinds of communication with the outside world through this channel. It is like the 'senses and hands' of the computer.
How it works
Data enters the system from input devices (keyboard, sensor), is processed by the processor and sent to output devices (display, speakers).
Where it is used
It is a fundamental concept in all computer programs and hardware interactions.
Frequently asked questions
Why is I/O a bottleneck?
Even if the processor works very fast, if the data input or output speed (for example disk speed) is slow, the system has to wait.
