AP Computer Science Principles Create Performance Task Terminology

Flashcards covering key vocabulary terms for the AP Computer Science Principles Create Performance Task.

Algorithm

A finite set of instructions that accomplish a specific task, constructed using combinations of sequencing, selection, and iteration.

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, dictionaries, or sets.

Input (Program)

Data that are sent to a computer for processing by a program, can be 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, also referred to as arrays or arraylists.

Output (Program)

Any data that are sent from a program to a device, can be tactile, audible, visual, movement, or text.

Parameter

An input variable of a procedure. Can be explicit or implicit.

Procedure

A named group of programming instructions that may have parameters and return values; also referred to as method, function, or constructor.

Program Functionality

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

Purpose (Program)

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

Sequencing

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

Student-Developed Procedure / Algorithm

Program code that has been written by the student who submitted the response.

Selection / Conditional Statement

Affects the sequential flow of control by executing different statements based on a condition being true or false.

List Being Used

The program is creating new data from existing data or accessing multiple elements in the list.
