This course will teach you everything you need to take and pass the CompTIA Network+ certification exam (N10-007). You will learn about the OSI seven-layer model, protocol suites, modern network operating systems, network hardware, cabling standards, remote connectivity, Internet connections, cloud computing, network security, network troubleshooting, and more.
In Lesson 1, we will examine the purpose of IT certifications, with specific emphasis on CompTIA Network+ and how it fits into the career of a network tech. We will 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 will 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 will 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.
Network Topologies and Standards
In Lesson 3, we will jump into network topologies and standards, exploring Ethernet in detail. You will 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 will 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 will delve into the protocol suite, discussing the many protocols included, how they work together, and what resources they require. We will also discuss the addressing and naming conventions used in TCP/IP networks and how computers get named.
In Lesson 6, we will delve into interconnecting networks, such as the Internet. Routers are the primary tools used for the job, so we will 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 will cover VLANs and virtual computing, and I’ll describe how complex networks use these technologies to accomplish specific goals.
Wide Area Networking
In Lesson 8, we will examine the many forms of remote connectivity, ways to interconnect a local computer or network with distant computers. We will discuss everything from older-style dial-up and T-1 lines to the latest satellite and fiber connections.
In this lesson, we will discuss the many aspects of network security. We will examine threats to your network, from social engineering to cracking encryption. Then we will look at the many ways the good guys combat the bad guys through authentication and authorization standards and protocols.
The Complete Network
In Lesson 10, we will start to put together everything you’ve learned so far in this course. You will get the scoop on designing and implementing both wired and wireless SOHO networks. We will also discuss categories of requirements, unified communication, specialized network devices, and industrial control systems.
In Lesson 11, we will roll up our sleeves and plunge into network troubleshooting. We will look first at the CompTIA Network+ troubleshooting model and then examine top network hardware faults. We will cover network hardware tools and finish the lesson with a discussion on troubleshooting WAN issues.
In this final lesson, we will look at a variety of practical concerns in network management, including emergency procedures, safety, segmentation, and network configuration and monitoring.

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.
