This course will teach you everything you need to know to take and pass the challenging CompTIA Network+ certification exam and become an excellent network technician. You'll learn about topologies, the OSI Seven-Layer model, protocol suites, modern network operating systems, network hardware, cabling standards, remote connectivity, Internet connections, network troubleshooting, and more. This course will prepare you for the 2009 exam objectives (N10-005 and JK0-016). CompTIA Network+ certification also counts as one of the elective exams for the Microsoft Certified Systems Administrator (MCSA) certification.
Please note that if you receive your EXAM TITLE certification before 1/1/2011, you will be a lifetime credential holder not subject to credential renewals. If you achieve the certification after 1/1/2011, you will be subject to a renewal process every three years. Register today to start working toward a lifetime credential!
Course Revised July 2013
A new session of each course starts monthly. If enrolling in a series of two or
more courses, please be sure to space the start date for each course at least two
All courses run for six weeks, with a two-week grace period at the end. Two lessons
are released each week for the six-week duration of the course. You do not have
to be present when lessons are released. You will have access to all lessons until
the course ends. However, the interactive discussion area that accompanies each
lesson will automatically close two weeks after the lesson is released. As such,
we strongly recommend that you complete each lesson within two weeks of its release.
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 to complete all of your course work,
including the final exam.
In Lesson 1, we'll examine the purpose of IT certifications, with specific emphasis on CompTIA Network+ and how it fits into the career of a network tech. We'll explore how networks work in general, covering such essential concepts as servers and clients, Ethernet, switches, and LANs. In the last two sections of the lesson, you'll examine two different models technicians have used to troubleshoot networks successfully: the OSI seven-layer model and the TCP/IP model.
In this lesson, you'll learn about all kinds of network connections, such as cable types—coaxial, twisted-pair, and fiber—and wireless options. It should be fun and informative and carry you deeper into the CompTIA Network+ journey.
Here in Lesson 3, we'll jump into network topologies and standards, exploring Ethernet in detail. You'll get a shorter look at some other standards that used to matter as well, including the star topology, so you won't be surprised by them on the CompTIA Network+ exam.
Network hardware enables networking devices—nodes—to connect together into a network. In Lesson 4, we'll cover all the major device types, such as switches, routers, and wireless access points, teaching how they function in modern networks.
Most modern networks use TCP/IP, so it's essential knowledge for competent techs. In Lesson 5, we'll delve into the protocol suite, discussing the many protocols included, how they work together, and what resources they require. We'll also discuss the addressing and naming conventions used in TCP/IP networks and how computers get named.
In Lesson 6, we'll delve into interconnecting networks, such as the Internet. Routers are the primary tools used for the job, so we'll explore how they work and the routing protocols they use.
In Lesson 7, I'll explain the many sides of virtualization, a process of using software to handle jobs traditionally serviced with hardware. We'll cover VLANs and virtual computing, and I'll describe how complex networks use these technologies to accomplish specific goals.
In Lesson 8, we'll examine the many forms of remote connectivity, ways to interconnect a local computer or network with distant computers. We'll discuss everything from older-style dial-up and T-1 lines to the latest satellite and fiber connections.
In this lesson, we'll discuss the many aspects of network security. We'll examine threats to your network, from social engineering to cracking encryption. Then we'll look at the many ways the good guys combat the bad guys through authentication and authorization standards and protocols.
In Lesson 10, we'll start to put together everything you've learned so far in this course. You'll get the scoop on designing and implementing both wired and wireless SOHO networks. We'll also discuss specialized network devices and network configuration management.
In Lesson 11, we'll roll up our sleeves and plunge into network troubleshooting. We'll look first at the CompTIA Network+ troubleshooting model and then examine top network hardware faults. We'll finish the lesson with a discussion on network hardware tools.
In this final lesson, we'll complete the network troubleshooting we began in Lesson 11, though this time we'll focus on software tools. You'll learn about essential network utilities to help you fix, maintain, and optimize your network.

With a Master of Arts degree in Medieval History, Scott Jernigan feels as much at home in the musty archives of London as he does in the warm glow of a computer monitor. Scott teaches A+ Certification and PC hardware classes around the country, including several stints at the FBI Academy in Quantico, VA, Lucent Technologies in Baltimore, MD, and the United Nations in New York City. Scott has also edited numerous computer books, including the best-selling "All in One A+ Certification Exam Guide" and the "Network+ Certification Exam Guide" from McGraw-Hill. Practicing what he teaches, Scott is an A+ and Network+ Certified Technician.
I am relatively new to this field and was surprised (and at first intimidated)to see people with many years of experience enrolled. However the class had something good for us all, be it updating or refreshing old skills or building brand new knowledge. Hats off to the instructor for a job well done. Thanks.
I enjoyed this class very much and found it to be very helpful. The instructor's writing style is very interesting and entertaining. I especially appreciate the way he presented the material such as stating the difference between passing the test and being a good technician.
I really enjoyed this courses, and will be taken more in the future. This will definitely help to advance in my current work environment. Thanks.
Thank you Scott, for doing a tremendous job for us. I feel very ready to sit for the Network + Certification now. Great work , thanks again!
This course has helped put into perspective the topics that I need to brush up on, in addition to providing me with the reference material that I need to do it.
