Pheidippides ran over 100 miles afoot to deliver the defeat of the Persians. Ships spent months at sea, caravans spent days or years in the dessert. And for what? To deliver a message. A message that can now in the form of a TCP/IP packet travel anywhere on Earth and beyond in fraction of the time! But how?

Join me to find out! We will cover the basics of networking, the web, servers, text messaging, social networks, and what will happened when humans want the internet they know and love... on Mars!
