A precise sequence of instructions for processes that can be executed by a computer

• Abstraction
• Algorithm
• Aggregation
• ASCII

A variable with local scope is one that can only be seen, used and updated by code within the same scope. Typically this means the variable was declared (created) inside a function -- includes function parameter variables. 

• Local variable
• Home variable
• Common variable
• Global variable

On-screen objects, like buttons, images, text boxes, pull down menus, screens and so on.

• UI Elements
• Type Elements
• Control Elements
• All of the above

The visual elements of an program through which a user controls or communications the application. Often abbreviated UI.

• Unlimited Internet
• User Interface
• Universal Images
• User Images

Dictates what portions of the code can "see" or use a variable, typically derived from where the variable was first created. (See Global v. Local)

• Variable Scope
• Variable View
• Variable Protocol
• Variable Interface

A placeholder for a piece of information that can change.

• Table
• Variable
• Shelf
• Data

An algorithm is..

• .. A set of instructions
• ... A motion block
• ... A character
• ... A loop statement 

A variable is used to:

• Store a value in memory
• Draw a circle
• Store a value that does not change
• Draw a rectangle

UI Elements include all of the following EXCEPT:

• Images

• Functions

• Pull Down Menus

• Text Boxes

It's important to understand in Event-Driven programming that:

• Only Users trigger events

• Only Events trigger code

• Both Users trigger events and events trigger code

• Neither Users trigger events or events trigger code
