Big Idea 2: Abstraction reduces information and detail to facilitate focus on relevant concepts. Enduring Understanding: A combination of abstractions built upon binary sequences can be used to represent all digital data. Learning Objectives: What students should be able to do: Describe the combination of abstractions used to represent data. [P3] Essential Knowledge: a A combination of abstractions is used to represent digital data. At the lowest level all digital data are represented by bits. Bits are grouped to represent higher-level abstractions including numbers and characters.

Abstraction is the process of taking away hiding something in order to reduce it to a set of essential characteristics. How do these represent abstraction. – Car – Internet – Digital data – Computer
