  1. BigIdea 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: • 2.1.1.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.

  2. 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

  3. Create a page for Blown to Bits in your Google site Create a page called: Blown to Bits On the page type: Vocabulary: • Bit – • Abstraction - • Koan - Chapter 1: Digital Explosion: Why Is It Happening, and What Is at Stake? • The Explosion of Bits, and Everything Else • Write a summary of what is the meant by explosion of bits. • What does the following statement mean “The digital explosion is creating both opportunities and risks”. Give examples from the reading to support your answer. • List the 7 Koans. Write a brief statement to explain what it means. • How do bits represent abstraction?
