Cryptography 101: Essential Terms & Communication Basics 🔐

We begin a new lecture series on cryptography today! In this series we will explore the basics of cryptography, such as different classic ciphers, some information theory and number theory, and some other related topics. Today we cover the concept of the communication channel and some basic terms. Ms. Kitty helps us in today's lecture.
