According to the Shannon’s definition, “The fundamental problem of communication is that of reproducimg at on point either exactly or approximately a message selected at another point”
This definition contains deep meaning, the “ message” means irrelevant to the engineering.
- Scheme of Basic Data Transmission
Example : Disk Storage

Shannon’s Information Theory
1. Measurement of Information
2. Source Coding Theory
3. Channel Coding Theory
All of these elements are described in simplre Mathematical Theory.
To measure information in term of Bits is using Probability Theory
Called as Entropy Function, P(xi) is expected value.

David Huffman, presented systematic method to achieve optimal compression called “Huffman Code”

## Channel
Communication has so much relation with the internet. Therefore, the major channel impairment herein is “Packet Loss” (term when we talk about internet).
- Binary Erasure Channel
