TCP & UDP

The internet wouldn’t exist as we know it if it weren’t for TCP and UDP, yet many developers don’t quite understand the technology powering the web. In this episode we talk with Adam Woodbeck, author of Network Programming with Go, to learn about TCP and UDP; what they are, how they work, and how one can experiment with tools like Wireshark and Go to learn more.
