Learn real-world applications for the concepts you learned in Introduction to Networking. Continue to build your knowledge of networks and networking, with detailed treatments of TCP/IP, how switches and routers operate, DNS, and more.
You will gain a full understanding of almost every aspect of networking technology, including hot topics such as virtual private networks, security, Internet connectivity, and cloud computing. Completion of this course and its prerequisite should serve as a springboard for a career in computer networking or training for CCNA Certification.
Learn about the concept of a network stack and compare its theoretical structure to real-world networking. You will trace how data travels through the computer for transmission on the network. Then, examine how a unit of computer data (a packet) gets from one computer to another.
Learn how routers create a virtual map of the entire Internet. You’ll also see how routers connect to different network types and transmit data across those different mediums. Then, discover the language of routers: routing protocols. You’ll learn why some routing protocols are appropriate for smaller networks, and why very large networks require specialized routing protocols.
Learn about IP addressing, the four primary IP address classes, and all about the various protocols that come packaged within TCP/IP. Then, learn the fundamentals of how computers enforce security. You’ll learn what a security descriptor is and how it can allow some people to only read a document, while others can delete or modify the document as much as they like.
Explore encryption, a method used to secure data for transmission over the Internet. While learning various encryption schemes, you will get firsthand knowledge of how a chunk of data gets encrypted, processed, and secured. Then, learn how you can create a virtual private network out of your Internet connection. You’ll get a hands-on view of how these private connections are made, and why they’re so useful.
Learn details about how DNS operates. You will learn how resource records are the building blocks of DNS, and how DNS scales to the entire Internet by being broken into zones. Then, examine the most important types of resource records, including A records, SOA records, and others. You’ll also learn about the two types of DNS queries: recursive and iterative.
Learn how Internet Servers operate, including how a web page is requested and transmitted to your computer, then displayed on your screen. You will examine the two primary Web protocols—HTTP and HTML. Finally, discover the differences between server-class operating systems and server-class computers, and discuss the various hardware components that comprise a true server-class computer. You will examine what cloud computing is, why it’s such a compelling platform, and how datacenters provide all that computing power.

When can I get started?
A new session of each course opens each month, allowing you to enroll whenever your busy schedule permits.
How does it work?
Once a course session starts, two lessons will be released each week for the six-week duration of your course. You will have access to all previously released lessons until the course ends.
How long do I have to complete each lesson?
The interactive discussion area for each lesson automatically closes two weeks after each lesson is released, so you’re encouraged to complete each lesson within two weeks of its release.
What if I need an extension?
The final exam will be released on the same day as the last lesson. Once the final exam has been released, you will have two weeks plus 10 days (24 days total) to complete the final and finish any remaining lessons in your course. No further extensions can be provided beyond these 10 days.
