O que se aprende nesse curso?
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.
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.
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.
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.
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.
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 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.
Configuring and Troubleshooting Hardware and Software
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.
