AP Computer Science Principles Terminology

Flashcards based on AP Computer Science Principles 2023 Scoring Guidelines focusing on terminology.

Input

Data sent to a computer for processing by a program.

Program functionality

The behavior of a program during execution, described by how a user interacts with it.

Output

Data sent from a program to a device.

Purpose

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

Program code segment

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

List

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

Collection type

Aggregates elements in a single structure (e.g., databases, hash tables).

Student-developed procedure / algorithm

Program code written by the student (individually or collaboratively).

Procedure

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

Parameter

An input variable of a procedure.

Algorithm

A finite set of instructions that accomplish a specific task.

Sequencing

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

Selection

Determines which parts of an algorithm are executed based on a condition being true or false.

Iteration

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

Argument(s)

The value(s) of the parameter(s) when a procedure is called.

Event

Associated with an action and supplies input data to a program.

List being used

Using a list means the program is creating new data from existing data or accessing multiple elements in the list.
