Which term best matches 'A piece of code that does part of a larger task'?

• A. Data
• B. Function
• C. Input
• D. Operating System (OS)

Answer: (B)

A piece of code that does part of a larger task is a function. A function is a self-contained block of code designed to perform a specific job within a program. It helps break a big task into manageable pieces, makes the code easier to reuse, test, and maintain, and is typically callable from other parts of the program, sometimes with inputs and often returning a result. Data are the values a program works with, not a code block themselves; input is data received by the program from outside; and the operating system is the software that manages hardware and basic services, not a specific code block within a program.
