Which term best matches 'A section of code that performs a single part of an overall program'?

• A. Data
• B. Operating System (OS)
• C. Index Number
• D. Module

Answer: (D)

Think of software organized into modules, each handling one piece of the program’s functionality. A module is a self-contained block of code designed to carry out a specific task within the larger system. This structure makes the program easier to understand, test, and maintain because changes stay localized to the relevant module and interfaces between modules are well-defined. Data is information, not code. The operating system is the overall software that manages hardware and provides services, not a single executable unit within a program. An index number is just a position used to locate items, not a chunk of code. So, the term that best fits a section of code that performs a single part of an overall program is a module.
