Internet General

A philosophy of making information and knowledge open and accessible to all people. A network of networks built on open, agreed upon protocols.

Protocol General

A widely agreed upon set of rules that standardize communication between machines.

Citizen Science General

Science that harnesses the power of many individuals to solve hard, complex problems.

Data General

Information (numbers, words, measurements, observations, etc) that is in a computer-readable form.

Number System General

Defines how we represent numbers. Which digits we can use, and what each position (place ) in a number means.

Decimal Number System General

The number system we use in out everyday lives. It has 10 digits, 0-9.

Binary Number System General

Number system that has 2 digits, 0 and 1. This is how computers represent numbers at the base level.

Hexadecimal Number System General

Number system that has 16 digits 1 - 9 and A - F.

Number System General

A number system defines how we represent numbers. It defines which digits we can use, and what value each position (place value) in a number has.

Binary General

The binary number system is the Base 2 Number System. It is a number system that only uses 2 digits (0 and 1).

Bit General

Bit means "binary digit". A bit is a single digit in a binary number. A bit can either be 0 or 1.

ASCII General

ASCII is the standard protocol for encoding text information as bits. The ASCII table assigns a unique binary number to every text character.

RGB Encoding General

The RGB encoding scheme allows us to encode colors such as numeric data. It defines the amount of Red, Green, and Blue light in a pixel.

Pixel Image General

An image can be represented as a grid of values. Each value encodes the color at that position in the image.

Number System General

Defines how we represent numbers. Which digits we can use, and what each position (place ) in a number means.

Hexadecimal Number System General

Number system that has 16 digits 1 - 9 and A - F.

Pixel General

Images are made up of pixels, which are essentially a grid of values. Each value, or pixel, encodes the color at that position in the image.

RGB Color Encoding General

The RGB encoding scheme allows us to encode colors as numeric data. It defines the amount of Red, Green, and Blue light in a pixel. Each color channel can have a value between 0 and 255.
