Logic Error

a bug in a program that causes something to happen incorrectly (example: writing a repeat instruction instead of a boolean).

Program

a collection of instructions.

Digital Data

a discreet representation of data without degradation using information in a set of individual symbols (not in a physical way).

Rapid Prototype

a draft or first attempt in something.

Byte

Binary (base-2)

a numeral system that comprises of 0 or 1.

Decimal (base-10)

a numeral system that comprises of 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9.

Pseudocode

a plain language (outline) description of the steps to an algorithm.

Syntax Error

a problem in the sequence of characters intended to be written (example: typo).

Compiler

Abstraction

Pair Programming

an efficient software device technique with a couple of people.

Run-Time Error

an error that occurs in the duration of the program while running.

Events

an occurrence recognized by software.

Bit

binary digit (0 or 1), a basic unit of information in computing communications.

Incremental

minute change in a variable or function.

Examples of Development Processes

prototype, rapid, spiral, waterfall, etc.

Iterative

repetition of a process.

Analog Data

represented using an infinite scale of values in a physical way.

Event-Driven Programming

the flow of a programming from user action.

Overflow Error

when a computer is unable to store an answer or calculation correctly.

Program Documentation

written text that assists in embedding the source code.
