You did it. You should be really proud of yourself
because getting through all of this material is a huge accomplishment.
The material we've covered has been pretty technical and
super complicated and getting through it all is a real feat.
Take a moment to think about just how much you've learned.
You now know a lot about how computers communicate with each other,
which is an essential part of how people communicate with each other.
Computer networks are used by billions of people
every day and they form the backbone of the global economy.
You've learned about how signals are carried across cables and
how many different protocols are used in
conjunction to make sure this data is delivered properly.
You've learned about all sorts of
network services like DNS that help humans use computers.
This is all very important to learn.
You'll be able to apply all of this knowledge into your I.T.
support career. You can also just use it to help your own home network run better.
Either way, congrats.
You've given yourself a leg up.
Next time you visit a social media site or
stream a video or even just chat with your friends and family online,
take a moment to think about how amazing it is that
so many different network devices and layers and protocols
are involved with every little bit of data sent across the Internet.
And you should also take a moment to marvel at the fact
that you now understand how all of that works.
Congratulations. In the next course,
Operating Systems and You,
becoming a power user.
My friend and colleague Cindy Quach,
will be your guide as you navigate the Windows and Linux OSes.
Get ready to have some fun and get your hands
dirty as Cindy teaches you how to become a command line wizard.
