CSP Unit 1: Digital Information

Innovation

A new method, idea, or product with a computer or program integral to its functionality 

Computing Innovation

An idea, product, or concept where a computer or program code is a fundamental part of its functionality

Technological Innovation

Using scientific and technical knowledge to create new or improved solutions that generate value 

Bit

The smallest unit of digital information. “Binary digit”

Nybble

A unit of data storage that consists of four bits, or half an eight-bit byte

Byte

A group of 8 bits

Binary

The base-2 number system using only 0s and 1s, which computers use to represent all data

Overflow Error

Occurs when a program attempts to store and process a number that exceeds the maximum value that can be represented by the available storage space. This happens because computers use a fixed number of bits to represent numerical values.

Round-off error

The imprecise representation of a number due to a computer’s inability to store it with infinite precision, resulting in a small difference between the computed value and its exact mathematical value.
