APCSP Creating Computational Artifacts 2

Question 1

Which of the following best describes a computational artifact?

Accepted Answer

Something created by a person using a computer, such as a program or image

Answer

A computational artifact is anything created by a human using a computing device, including programs, images, audio, video, or presentations.

Question 2

A student uses a drag-and-drop tool to build a mobile app without writing code. This is an example of what type of development environment?

Accepted Answer

Visual/block-based programming environment

Answer

Visual or block-based environments allow users to create programs by dragging and connecting components rather than writing text-based code.

Question 3

When iterating on a computational artifact, a developer reviews user feedback and makes improvements. What phase of development does this represent?

Accepted Answer

Testing and refinement

Answer

Reviewing feedback and making improvements is part of the testing and refinement phase, which is a core component of the iterative development process.

Question 4

Which of the following is the BEST reason to use version control when creating a computational artifact?

Accepted Answer

To track changes and revert to earlier versions if needed

Answer

Version control systems track changes over time so developers can revert to earlier versions, compare changes, and collaborate without losing work.

Question 5

A programmer decomposes a large music composition tool into separate modules for recording, editing, and playback. What benefit does this provide?

Accepted Answer

It makes each module easier to develop, test, and maintain independently

Answer

Decomposing a program into modules allows each piece to be built and tested independently, simplifying development and maintenance.
