Abstraction is a fancy word for summarizing or explaining in a way that we can easily understand. A map is an abstraction of the Earth. The speedometer on a car as an abstraction for how fast the car is going.
Newbie: The entirety of this GenCyberCards Cyber Realm game is for abstraction. A whole lot of very smart people invented the technology that fuels our modern age, but we simply cannot know all of it. So instead, we made a fun game with examples and easy metaphors to more easily understand and implement the technology. We may not need to know how the technology was made or works fully, but we do need to know how to use it properly.
