I/O (Input/Output)

Input/Output (I/O) refers to the processes by which a computer communicates with the outside world. Input involves receiving data or commands from devices like keyboards, mice, or sensors. Output is when the computer sends information to peripherals such as monitors, printers, or speakers. Together, I/O enables computers to interact with users and the environment, facilitating data exchange that allows programs to function effectively. It’s like a conversation: input is what you tell the computer, and output is what it responds with.
