Glossary of Terms
All complex subjects have their own terminology that sometimes makes it hard for new people to break into the field. This sometimes includes uncommon words, but more often than not a subject will have very specific meanings for common words - the discussion of errors vs mistakes in this video is a good example of this.
This glossary is a reference of some of the uncommon terms and specific definitions of more common words that you will encounter throughout Data Tree and your broader dealings with data.
Many of these definitions come from the course materials and experts that helped develop Data Tree. Others come from the CASRAI Dictionary. Those definitions are kindly made available under a Creative Commons Attribution 4.0 International License.

In the electromagnetic spectrum, the visible light region lies from violet at shorter wavelengths/energies to red at longer wavelengths/energies. Infrared radiation has wavelengths just greater than red light and emitted particularly by heated objects. For example, night vision goggles use infrared radiation.
A number which is not a fraction; a whole number.
Internet of Things
Abbreviated to IoT, a broad term for devices interconnected via the internet enabling sending and receiving of data or instructions. These devices include everyday items such as home appliances or cameras. Sometimes also referred to as â€˜smart devices'.
The capability to communicate, execute programs, or transfer data among various functional units in a useful and meaningful manner that requires the user to have little or no knowledge of the unique characteristics of those units.
