AP Computer Science Principles 2025 Scoring Guidelines

These flashcards cover key terminology and definitions important for understanding AP Computer Science Principles.

Algorithm

A finite set of instructions that accomplish a specific task.

Arguments

The values of the parameters when a procedure is called.

Code segment

A collection of program statements that are part of a program.

Collection type

Aggregates elements in a single structure, such as databases, hash tables, or dictionaries.

Input

Data that are sent to a computer for processing by a program in various forms such as tactile, audible, visual, or text.

Iteration

A repetitive portion of an algorithm that repeats until a given condition is met or for a specified number of times.

List

An ordered sequence of elements allowing multiple related items to be represented using a single variable.

Output

Any data sent from a program to a device in forms like tactile, audible, visual, movement, or text.

Parameter

An input variable of a procedure, which can be explicit or implicit.

Procedure

A named group of programming instructions that may have parameters and return values.

Program functionality

The behavior of a program during execution, often described by user interaction.

Purpose

The problem being solved or creative interest being pursued through the program.

Selection / conditional statement

A statement that affects the flow of control by executing different statements based on a condition.

Sequencing

The application of each step of an algorithm in the order the code statements are given.

Student-developed procedure / algorithm

Program code that is written by the student who submitted the response, excluding existing code or libraries.
