Key Points:
•Designed for efficiency: Built around English letter frequency.
•Common letters = short signals:

•Rare letters got longer codes:
•Example: Z = --..
•Alfred Vail refined the system:
•Analyzed letter frequency using newspaper type.
•The Original idea was numbers only:
•Morse planned a codebook system
•Vail expanded it to include the full alphabet.
Result: A fast, learnable, resilient communication system.
