Computing innovation

Includes a program as an integral part of its function; can be physical non-physical software or a non-physical concept

Pair programming

A collaboration model with a driver at the keyboard and a navigator watching for logic and direction

Program

A collection of program statements that performs a specific task when run by a computer

Code segment

A collection of program statements that is part of a program

Behavior

How a program functions during execution; often described by how a user interacts with it

Program input

Data sent to a computer for processing; tactile audio visual or text

Event

An action that supplies input data to a program and affects the flow of execution

Event-driven programming

Statements execute when triggered rather than through sequential flow of control

Program output

Any data sent from a program to a device; usually based on input or prior state

Iterative development

Refinement and revision based on feedback testing or reflection; may revisit earlier phases

Incremental development

Breaking the problem into smaller pieces and verifying each before adding it to the whole

Specification

The definition of the requirements for a program

Program requirements

A description of how a program functions including required user interactions

Program documentation

A written description of the function of a code segment event procedure or program and how it was developed

Comment

Documentation written into a program for people to read; does not affect how the program runs

Logic error

A mistake that causes a program to behave incorrectly or unexpectedly

Syntax error

A mistake where the rules of the programming language are not followed

Run-time error

A mistake that occurs during the execution of a program

Overflow error

An error that occurs when a number falls outside the defined range of values

Defined Inputs

Test Inputs chosen to demonstrate expected outcomes at or just beyond the extremes of the data
