Data Compression II: Using a Different Notation => Redundancy Compression
In the previous lectures, when referring to the state field, we used 2 ASCII bytes=16 bits. Was that really necessary?
Answer: Since there are only 50 states, we could encode them all with only 6 bits, thus saving 1 byte per state field.
Disadvantages:
- Not Human-Readable
- Cost of Encoding/Decoding Time
- Increased Software Complexity (Encoding/Decoding Module)
