Other than "programming" languages, how do computers talk in secret code?
Across the internet, there are different ways that information is represented to make the whole world ultimately interconnected.
Activity: Let's try sending each other morse code messages!
How can I encode a message of letters?
One of the more well-known encoding schemes, the Caesar Cipher encodes English letters by shifting each letter forward by a certain number of steps.
Has anyone actually used these ciphers for real-world purposes?
Yes! A cool example is the Book Cipher, where a real book is used to hide messages. It has a history dating back to the American Revolution.
