- [Greg] Protocol is a lifeblood of modern communication,
every website, email, and bank transaction depends on them.
I'm Greg, and I've been building networks worldwide
for over 15 years.
In this course, I'll discuss the basic building blocks
that protocols use.
I'll then move up discussing how websites are delivered,
how domain names are resolved,
and how voice traffic is carried on a network.
Last, we will get hands on and show the essential tools used
when troubleshooting your connection to the world.
I'm ready to rock,
so grab your gear and let's get started
with foundations of networking CLI.
