block 10 encoding and cryptography

How does a computer turn letters, images, and secret messages into strings of binary digits? In this block, you will explore the fascinating world of data encoding and cryptography. You will learn how characters are represented using ASCII and Unicode, how data compression reduces file sizes without losing vital information, and how error-checking methods prevent corruption during transmission. Finally, you will dive into the history of cryptography, discovering how ancient ciphers and modern bitwise operations keep our digital communications secure.
