Introduction
In today's session we'll be discussing data and the many ways we can represent it.
Reminders and Prerequisites
For this session you'll need:
- Basic knowledge of Python (as seen in the first session)

What is Data?
Data is information.
This plain text is data, but more than that, data can be encoded and represented in many ways.
Generally, we represent data in a suitable format for our specific purpose.
For example, if we want the most basic way to encode data, the one that computers "think" in, we'll use Binary.
Sometimes, we need our data to not be confused with something else, so, for example we encode Binary to Base-64 in order to get the information on the other side of the wire uncorrupted.
