AP Computer Science Principles

EXAM PREPERATION

Abstraction

Filtering out unnecessary characteristics to focus on essential ones.

Symmetric encryption

Encryption technique using a single key for decryption and encryption, requiring privacy.

Distributed computing

Computational model utilizing multiple devices to execute different parts of a program.

Parallel computing

Utilizing multiple processors on a single computer to process tasks simultaneously.

Fault tolerance

System's ability to operate without interruption despite component failures.

Sequencing

Sequential execution of steps in an algorithm or program.

Selection

Boolean condition determining the path taken in an algorithm or program.

Iteration

Repeating steps in an algorithm for a specific number of times or until a condition is met.

Heuristic

Technique aiding algorithms in finding solutions for complex problems.

Bandwidth

Maximum data transfer capacity over a network connection in a fixed time period.

IP (Internet Protocol)

Protocol for addressing nodes on a network and routing data between nodes.

World Wide Web

System of interconnected pages, media, and files accessible via HTTP.

HTTP (Hypertext Transfer Protocol)

Protocol for requesting webpages and submitting form data.

Crowdsourcing

Collaborative model where online users contribute to projects, ideas, or services.

Citizen science

Involving public volunteers in scientific research projects.

Creative Commons

Alternative to copyright allowing creators to specify sharing terms for their work.

Encryption

Process of scrambling data to prevent unauthorized access.

Public key encryption

Asymmetric encryption using different keys for encryption and decryption.

Cookie

Small text piece tracking user information on websites.

Phishing

Deceptive attack to trick users into revealing private information.

Rogue access point

Unauthorized wireless access point capturing network traffic.
