A new session of each course opens each month, allowing you to enroll whenever your busy schedule permits!
How does it work? Once a 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.
Keep in mind that the interactive discussion area for each lesson automatically closes 2 weeks after each lesson is released, so you’re encouraged to 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 2 weeks plus 10 days to complete the Final and finish any remaining lessons in your course. No further extensions can be provided beyond these 10 days.
Lesson 01 - Network Fundamentals
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.
Lesson 02 - Network Media
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.
Lesson 03 - Network Topologies and Standards
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.
Lesson 04 - Network Hardware
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.
Lesson 05 - TCP/IP
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.
Lesson 06 - Routing
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.
Lesson 07 - Virtualization
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.
Lesson 08 - Wide Area Networking
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.
Lesson 09 - Network Security
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.
Lesson 10 - The Complete Network
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 categories of requirements, unified communication, specialized network devices, and industrial control systems.
Lesson 11 - Troubleshooting Networks
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 cover network hardware tools, and finish the lesson with a discussion on troubleshooting WAN issues.
Lesson 12 - Network Management
In this final lesson, we'll look at a variety of practical concerns in network management, including emergency procedures, safety, segmentation, and network configuration and monitoring.
