What does I/O stand for in computing?

Explanation:
The main idea is that I/O describes how data moves between a computer and the outside world. The I stands for Input, the data the system receives from users or devices (like a keyboard, mouse, disk, or network). The O stands for Output, the data the system sends out to display, print, or transmit elsewhere. Together, they capture the common flow of information: bringing data in and sending results back out. This term is used for both hardware and software aspects—I/O devices enable the transfer, while I/O operations are the actions that read or write data in programs. The other options aren’t standard expansions of I/O, so they aren’t used to describe this concept.
