• A way of representing information using only two options.

• 8 bits

• A contraction of "Binary Digit";  the single unit of information in a computer, typically represented as a 0 or 1

• Data that changes discretely through a finite set of possible values

A process for reducing the number of bits needed to represent something without losing any information. This process is reversible.

• Lossy Compression

• Sampling

• Lossless Compression

A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This process is not reversible.
