This video covers the various Ethernet cabling types, such as straight-through and crossover cables. Understanding the various cables used is crucial to passing the CCENT exam. Don't skip the foundation videos. The internetworking, OSI, and Ethernet area all very important in the CCENT objectives.

- [Instructor] Now in discussing our Ethernet cable types,…we have straight-through, crossover and rolled…but regardless we always use four wire pairs.…Now, in a straight-through cable we only need four wires…to connect Ethernet devices together.…It's relatively simple to create this type…and this graphic shows the four wires used…in a straight-through Ethernet cable.…Notice that pins one to one, two to two, three to three…and six to six are used.…So we just connect, like I said, one to one, two to two…and so on and you'll be up and networking in no time.…
However, remember this will only be ten megabits,…maybe you can get a 100 megabits working today…but it's certainly not gonna work with gigabit, voice…or other LAN or WAN technologies for sure.…Now, let's take a look at a straight-through cable here,…what we would use it for.…So in this graphic here we can see that we typically…would have a host to a switch or hub and we transmit,…what's important to understand here is we transmit…on pins one and two.…So this is what's referred to as our transmit pairs…
