Information Theory The Big Idea Reading Answers Passage
Information Theory- The Big Idea
Information theory lies at the heart of everything - from DVD players and the genetic code of DNA to the physics of the universe at its most fundamental. It has been central to the development of the science of communication, which enables data to be sent electronically and has therefore had a major impact on our lives
1. Paragraph A – iii. Repairing Voyager I from a distance
Explanation: Paragraph A describes how NASA sent a repair message to Voyager I, emphasizing the challenge of communicating over 12 billion kilometers.
2. Paragraph B – ii. Shannon’s early influences and career
Explanation: Paragraph B highlights Shannon’s life, his early math talent, and his communication science contributions.
3. Paragraph C – vi. A simple goal that led to major discoveries
Explanation: Paragraph C explains Shannon’s initial goal to define 'information' and how this led to significant breakthroughs.
4. Paragraph D – viii. The impact of noise on communication
Explanation: Paragraph D focuses on how noise affects communication and how Shannon measured this mathematically.
5. Paragraph E – i. How Shannon’s ideas are used today
Explanation : Paragraph E illustrates the practical use of Shannon’s theories, such as in bar codes and space missions.
6. Paragraph F – vii. Shannon’s method of storing data efficiently
Explanation: Paragraph F explains how Shannon's work influenced data compression, reducing message redundancy.
