HACKBRIGHT TECH TALK: How the Internet Works

OpenDNS software engineer Philip Thomas will be speaks about network communications at Hackbright Academy. Recorded on Tuesday, May 27, 2014.

About the Talk: The Internet is ubiquitous throughout modern life. What actually happens when you type "google.com" into your browser? This talk seeks to answer that question starting with the basics of network communication then moving into how BGP makes the Internet different than a home network. Emphasis will be placed on topics relevant to software engineers.

The talk consists of three main topics. First, we look at how computers talk to each other by examining Internet protocols with a focus on TCP. Next, we look at what makes the internet unique and the types of challenges that were solved in expanding computer networks to the world with focuses on BGP and DNS. Finally, we will look at advanced Internet topics that are of interest to developers, including anycast, IPv6, and HTTP.
