Big Idea 5: Impact of Computing. College Board exam weighting listed for this unit: 21%−26% of exam score.

What to Know

Track how variables, objects, lists, or data change step by step.
Watch boundary cases, indexes, loop conditions, and return values.
Use abstraction to hide details only after the behavior is clear.
Always connect this topic back to the larger unit: Impact of Computing.

Detailed Notes

The digital divide is part of the social impact side of computing. Study it by asking who benefits from a technology, who may be excluded or harmed, and what design choices, policies, or access barriers create that outcome.

In AP Computer Science Principles, AP questions may ask you to explain consequences of computing systems, not just how the systems work. A strong answer identifies the affected group, the computing practice involved, and a specific benefit, risk, or tradeoff.

Use concrete examples. For instance, access to devices, internet speed, language support, disability access, data collection, privacy settings, or algorithmic decisions can all change whether a technology is useful, fair, and safe.

Key Vocabulary

The digital divide

Unequal access to computing devices, reliable internet, digital skills, or useful technology across different groups or communities.

Algorithm

A finite sequence of steps used to solve a problem.

Iteration

Repeated execution of a set of steps.

Selection

Use of a condition to choose which code or action should run.

Data abstraction

A way to manage complexity by naming and organizing data.

Computing impact

A benefit, harm, or tradeoff caused by a computing innovation.
