Unit 3 - Intro to App Design

Vocabulary from Slides

• 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.

• Event-Driven Programming: some program statements run when triggered by an event, like a mouse click or a key press

• Documentation: a written description of how a command or piece of code works or was developed.

• Comment: a form of program documentation written into the program to be read by people and which does not affect how a program runs.

• Pair Programming: a collaborative programming style in which two programmers switch between the roles of writing code and tracking or planning high-level progress

Other Terms from Framework

• App Screen Size: the x-axis runs across the page, and the y-axis runs down the page. The origin is NOT in the middle but rather, at the top left of the screen.

• CamelCase: a typographical convention in which an initial capital is used on the first letter of the SECOND element name (example: iPhone, redButton, musicPop)

• Debugging: Finding and fixing problems in an algorithm or program.

• Development process: the steps or phases used to create a piece of software. Typical phases include investigating, designing, prototyping, and testing

• Event: associated with an action and supplies input data to a program. Can be generated when a key is pressed, a mouse is clicked, a program is started, or by any other defined action that affects the flow of execution.

• Incremental Development Process: a design approach that breaks the problem into smaller pieces and makes sure each piece works before adding it to the whole.

• Iterative Development Process: a design approach requires refinement and revision based on feedback, testing, or reflection throughout the process. This may require revisiting earlier phases of the process.

• Plagiarism: The use of material created by someone else without permission and presented as one’s own

• Program Requirements: descriptions of how a program functions and may include a description of user interactions that a program must provide.

• Program specification: a description of all the requirements for the program.

• Syntax Error: a mistake in the program where the rules of the programming language are not followed.

• Software: A program or a collection of programs
