CompTIA Network+, and all the exam objectives for the N10-005 exam. You'll learn how to maintain, secure, troubleshoot, install, control, and configure basic network infrastructure. This Network Plus course offers the perfect way to kick off your network admin career or improve on the networking skills you already have. It's also a terrific introduction to computer networking for business professionals of any stripe.

This exciting course begins by providing you a solid foundation of how computer networks operate, and builds upon that knowledge with real-world examples of network technologies and protocols including the OSI model, TCP/IP, DNS, ARP, IP addressing (including sub-netting), and media types and connectors including fiber optics, copper, and wireless.

6. NC: Well-Known Ports (34 min)

For each popular application layer protocol, (such as HTTP for surfing the Web, DNS to find out what IP address we can use to reach Google.com, and SMTP for sending email), there is a "Well-Known Port" that is associated with each of these protocols. In this Nugget, Keith discusses the reason for these ports, demonstrates them in action and takes you behind the scenes with a protocol analyzer to reinforce what you have learned. Maps to exam objective 1.5

7. NC: The Functions of Common Protocols (55 min)

So what does ARP do, and how does my computer know which IP address it should send a packet to when accessing a Google server? These are just a few of the questions that are answered in this Nugget as Keith reviews several of the protocols in the TCP/IP protocol suite, and introduces you to a few new ones as well. To complete this fun Nugget, Keith provides a demonstration of a computer that joins the network and accesses a Web server, and then we go behind the scenes with a protocol analyzer to confirm the details of how DHCP, ARP, DNS and HTTP were all functioning to make the Web request possible. Maps to exam objective 1.6

8. NC: Digging into the Details of DNS (32 min)

How do we find the phone number of a friend? Usually we will look at some type of online database or phone book, that can provide the phone number based on their name. How does a computer find the IP address of a Web server? As we learned in a previous Nugget, the computer will use the Domain Name System (DNS). On the surface, it looks fairly simple: The computer asks a DNS server, and the DNS server replies, but behind the scenes, there are thousands of servers cooperating together to make this all possible. In this Nugget, Keith provides a sneak peak behind the scenes of the inner workings of the Domain Name System, as well as some tools you can use to verify and troubleshoot DNS. Maps to exam objective 1.7

9. NC: Using a Method When Troubleshooting (33 min)

When the network goes "bump" in the night, and users have lost access, it can be a stressful time for both the users and you, the network technician. By having a method to follow when troubleshooting can give you the edge (and confidence) to ask the right questions, isolate the problem, and get the network up and running. In this Nugget, Keith walks you through using a methodology to do live troubleshooting on network that has been used in class since the first Nugget of this series. Maps to exam objective 1.8

10. NC: Moving to Virtual (32 min)

The world is a changing place, and when a new idea comes along that makes sense, and saves money, it usually moves forward. This is the case with virtualization. In the old days, when a company needed a new server, they would buy one physical sever, install the software, and add it to the network. This process usually took weeks. Now, new servers can be brought online in a "virtual" environment, and be up and running in only minutes. In this Nugget, Keith describes the concepts of how virtualization is possible, then he takes you behind the scenes of how it is done with live examples of virtualized Servers, workstations, routers and switches. Maps to exam objective 1.9

11. Network Installation and Configuration: Routers and Switches Part 1 of 2 (42 min)

Leveraging the fundamentals we learned in the previous Nuggets, it's time to put network pieces together for a functional network. In this Nugget (part 1 of 2), Keith walks you through the configuration of a router including interfaces, routing, access-lists and more. You will also discover the ho
