The legend continues!

[@sobrefingerskate]

awesome as always.God bless

[@cheesybeast1721]

I didn't know this turned into an HVAC course lol

Can you expound some more about the cable not having speed?

[@professormesser]

It's a hunk of copper. It just sits there. It has no speed. The signal on the cable is the thing that has a speed.

[@R-ce9yj]

@professormesser Thanks for replying. The signal is the actual category? If not, why then label the cable like that?

[@professormesser]

The road isn't the measurement of speed. The car engine determines how fast you will go. The category is a description of the cable's capabilities. The category ensures the cable can support a particular signal type. Different Ethernet standards require different categories of cable, depending on how fast they need to go. For example, The IEEE standard for 1000BASE-T describes a 1 gigabit speed of Ethernet. The standard specifies you need a minimum of a category 5 cable to support this speed.

@@professormesser I do get the road analogy, but the explanation about in the next paragraph kinda throwing me off. I'm really trying to understand this because I don't just want to pass the exam, but to fully grasp the concepts. I'm a hobbyist running a small WISP I started up and this is very important to me. With that said, let's say a Cat 4 can only facilitate a 10 Mph speed, and a cat 5 can take a max of 100 Mph...wouldn't it be fair to say the cable determines the speed? What am I missing?

[@renejacques8288]

I've always associated Ethernet to RJ45 because I always hear Ethernet cable. Was I incorrect?

[@eg1525]

I believe so, Ethernet could be as much fiber as RJ45 as any other type of connector/cabling, as long as it's a wired connection.
