What does I/O stand for?

I/O stands for Input/Output, which refers to the communication between an information processing system and the outside world. This term is fundamental in computing and technology, signifying how data is received (input) and sent out (output) by devices and software systems.

Input can include data entered through peripherals like keyboards, mice, or sensors, while Output encompasses the results displayed on screens, sent to printers, or transmitted to other devices. Understanding I/O is crucial because it highlights the processes involved in data handling and system interaction within various technologies. This concept is central to computer architecture and programming, reflecting how users and applications interact with computer systems.
