AP CSP Unit 3 Review

User Interface:

the inputs and outputs that allow a user to

interact with a piece of software. User interfaces can include a

variety of forms such as buttons, menus, images, text, and

graphics.

Input:

data that are sent to a computer for processing by a

program. Can come in a variety of forms, such as tactile

interaction, audio, visuals, or text.

Output:

any data that are sent from a program to a device. Can

come in a variety of forms, such as tactile interaction, audio,

visuals, or text.

Program Statement:

a command or instruction. Sometimes also referred to as a code

statement.

Program:

a collection of program statements. Programs run (or “execute”) one command at

a time.

Sequential Programming:

program statements

run in order, from top to bottom.

No user interaction

Code runs the same way every time

Event Driven Programming:

some program

statements run when triggered by an event, like a

mouse click or a key press

Programs run differently each time depending

on user interactions

Documentation:

a written description of how a

command or piece of code works or was

developed.

Comment:

form of program documentation

written into the program to be read by people and

which do not affect how a program runs.

Debugging:

the process of finding and fixing problems in code

• Describe- The problem

• Hunt- For bugs

• Try- Solutions

• Document- As you go

Pair Programming:

a collaborative

programming style in which two

programmers switch between the roles of

writing code and tracking or planning high

level progress

Event handling

a programming concept where a program waits for an event to occur, such as a user clicking a button or data being input, and then executes a specific function, called a handler or listener, to respond to that event

Event listener

a fundamental concept in event-driven programming, allowing applications to react to various occurrences or "events" within a system. These events can originate from user interactions (like clicks, key presses, or mouse movements), system-level actions (like page loading or network requests), or other programmatically triggered occurrences.

(UI) elements

the interactive and informational building blocks of a digital product's interface
