Which term describes "input/output" in programming?

The term that describes "input/output" in programming is data flow. Data flow refers to the movement of data through a system, including how input is received and processed to produce output. In the context of programming, input refers to the data received by a program, and output is the result after processing that data. Understanding data flow is crucial for designing programs that effectively handle information, ensuring that inputs are correctly transformed into desired outputs.

Input/output operations are critical components of virtually every program, where user interactions, file reading/writing, and communication between different systems take place. Recognizing the significance of data flow allows programmers to visualize how data moves through their applications and to identify points where data can be manipulated or transformed.
