Introduction to Networking
Welcome to the Networking course of the IT Support Professional Certificate! In the first week of this course, we will cover the basics of computer networking. We will learn about the TCP/IP and OSI networking models and how the network layers work together. We'll also cover the basics of networking devices such as cables, hubs and switches, routers, servers and clients. We'll also explore the physical layer and data link layer of our networking model in more detail. By the end of this module, you will know how all the different layers of the network model fit together to create a network.

This was extremely intensive, and informative. I'm really looking forward to applying my newfound knowledge to the test at an IT Support job/internship!
Awesome. Learned a lot. Can't wait to finish the other 4 courses remaining.
I loved every minute of this course. Every thing I have learned has been so practical and useful. The instructor was great! I feel confident I could now explain the basics of computer networking to anyone.

This course was slightly harder than the first one. I didn't understand at first why I was learning so much about data transmission until near the end of the course. Taking this course will really help you appreciate how complicated the protocols and established services are to building a network and making the internet work as a collaborative whole. This takes understanding networking to a way higher level, and is worth it for anyone pursuing a career in IT.
