Not every copper connection is the same. In this video, you’ll learn about RJ11, RJ45, F-connectors, and BNC copper connectors. << Previous: Fiber Connectors Next Video: Network Topologies >> One common copper connector we use on our networks today is an RJ11. This stands for Registered Jack type 11. It is a six-position connector, but […]

There are many different ways to connect optical fiber devices. In this video, you’ll learn about LC, SC, ST, and MPO fiber connectors. << Previous: Network Transceivers Next Video: Copper Connectors >> When working with fiber optics, one of the first things you’ll notice is there are many different connector types. You have to make

Transceivers are used to provide a modular networking environment. In this video, you’ll learn about Ethernet transceivers and the differences between SFP, SFP+, QSFP, and QSFP+. << Previous: Copper Cabling Next Video: Fiber Connectors >> Transceiver is a combination of two words– “transmitter” and “receiver.” And these are usually combined within the same piece of

There are many different copper cable types used in modern networks. In this video, you’ll learn about twisted pair cable, coax, and the importance of plenum-rated copper cables. << Previous: Wireless Networking Next Video: Network Transceivers >> Cabling is the foundation of everything we do in networking. Whether you’re using a router, a switch, a

If you are networking over an extended distance, you’re probably using optical fiber. In this video, you’ll learn about multimode and single mode optical fiber technologies.  << Previous: Wireless Networking Next Video: Copper Cabling >> Many of us are accustomed to using twisted pair copper, especially if we have networks that we use at home

Every Ethernet device in the world can communicate with every other Ethernet device, thanks to the international standards. In this video, you’ll learn how Ethernet standards are created and updated. << Previous: Wireless Networking Next Video: Optical Fiber >> If you’ve connected your computer to a wired network, then you’re probably using Ethernet. Ethernet is

We use many different wireless standards in the IT industry. In this video, you’ll learn about 802.11 wireless networks, 4G, 5G, and satellite networking. << Previous: Network Communication Next Video: Ethernet Standards >> If you connect to a network at work or at home, then you’re probably very familiar with wireless networks. You may have

Communication between network devices can occur in different ways. In this video, you’ll learn the difference between unicasts, multicasts, anycasts, and broadcasts. << Previous: Other Useful Protocols Next Video: Wireless Networking >> A unicast is one of the more popular ways of sending information across the network. It is when one station sends information directly

We rely on many different protocols to manage and connect our network devices. In this video, you’ll learn about ICMP, GRE, and IPsec protocols. << Previous: Common Ports Next Video: Network Communication >> There will be many times as a network professional when you’d like to know if a device is on the network and

Port numbers can help provide identification and management of application traffic. In this video, you’ll learn about well-known port numbers for popular applications. << Previous: Introduction to IP Next Video: Other Useful Protocols >> As a networking professional, you may be asked to configure port numbers associated with a particular application.
