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 is 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 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.
Development process
The steps or phases used to create a piece of software. Typical phases include investigating, designing, prototyping, and testing.
Investigating
getting requirements, interviewing users about wanted functionality
Designing
How the program will work or how users interact with it
Prototyping
Creating a model
Testing
Testing functionality of program
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 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
