Unit 3 (Intro to App Design) Flashcards
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:
form of program documentation written into the program to be read by people
and which do 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
Debugging:
Finding and fixing problems in an algorithm or program. describe the problem, hunt for bugs, try solutions, document as you go
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.
