explains the purpose of every major piece of computer code and also identifies and describes key variables. Select one: a. Systems documentation b. Agile documentation C. User documentation d. Technical documentation Time left 0:53:42
The correct answer and explanation is:
Correct Answer: d. Technical documentation
Explanation:
Technical documentation serves the essential purpose of explaining how a computer program or system works. It is written primarily for developers, engineers, and IT professionals who are involved in the creation, maintenance, or upgrading of the system. Among its most critical functions is to explain the purpose of every major piece of computer code and to identify and describe key variables within that code. This ensures that any developer reading the documentation can understand the program’s structure, logic, and flow without having to decipher every line of code manually.
This kind of documentation often includes:
- Descriptions of functions and modules: It outlines what each part of the code does and how the components interact.
- Variable definitions: Each key variable is named and explained, including its data type, purpose, and scope.
- Examples of how to use functions or APIs: This helps new developers understand practical implementation.
- Error handling and exceptions: Notes on what kinds of errors the code anticipates and how they are handled.
Technical documentation is vital during debugging, maintenance, and system upgrades. It ensures consistency when multiple developers work on the same project and supports knowledge transfer if original developers leave the project.
The other options listed are not as specific in their focus:
- a. Systems documentation describes the overall system architecture but does not go deeply into code and variable-level detail.
- b. Agile documentation is minimal and often limited to what’s needed for rapid development cycles.
- c. User documentation is created for end-users and focuses on how to operate the software rather than how it works internally.
Therefore, the correct and most accurate choice is technical documentation.
