ALGORITHM

• A process of repeating a set of instructions a specified number of times or until a condition is met.
• A technique or process that manages complexity in a program or computer system.
• A set of steps to accomplish a task.
• To identify errors or bugs in computer hardware or programs and fix them.

ABSTRACTION

• In MIT App Inventor, a control block that looks for inputs or events to know when to perform a specific action.
• A technique or process that manages complexity in a program or computer system.
• A set of steps to accomplish a task.
• A classification of data or “class type” that defines what a data item is or is not, such as integer, float, string, or Boolean.

CODE

• Information or signals produced or delivered by a computer system.
• A technique or process that manages complexity in a program or computer system.
• Information or signals entered into a computer system.
• A set of program instructions.

INPUT

• Information or signals entered into a computer system.
• A set of program instructions.
• A means to create computer programs by manipulating elements graphically rather than using text.
• The set of rules that defines the combinations of symbols that are considered to be correctly structured in that language. The grammar and spelling of text-based programming languages.

OUTPUT

• An action or occurrence that happens during runtime that will trigger a response or behavior by the software.
• To identify errors or bugs in computer hardware or programs and fix them.
• Information or signals produced or delivered by a computer system.
• A process of repeating a set of instructions a specified number of times or until a condition is met.

SYNTAX

ITERATION

• A technique or process that manages complexity in a program or computer system.
• A set of steps to accomplish a task.
• Information or signals produced or delivered by a computer system.

Data Type

• A set of program instructions.
• A technique or process that manages complexity in a program or computer system.
• The set of rules that defines the combinations of symbols that are considered to be correctly structured in that language.
• A classification of that defines what a data item is or is not, such as integer, float, string, or Boolean.

String

• Text or characters displayed by a program.
• A block of organized and reusable code that performs a single action
• A collection of data values that do not have to be the same type
• A set of steps to accomplish a task.
