This is called a unshielded twisted pair Ethernet cable, very boring, using a.
What is it it's like well done.
Now, if you connecting one device to another, you once again need some kind of media that allows for
a data transmission from one device to another.
In other words, you need some type of data link to allow data to be transferred from one device to
another.
I've already shown you Ethernet.
This is a very common type of Ethernet.
This is Cat five or Category five.
We'll talk more about Ethernet later.
But Cat five, this is an example of Cat six Ethernet cabling, unshielded twisted pay.
Ethernet cabling like this is probably the most common type of cabling that you're going to encounter.
But it didn't start there.
Now, Ethernet didn't start with unshielded twisted cabling, it started with 10 base five cabling,
very big cabling.
That's not easy to use.
It actually has these black markings on the cable.
And that's where you would use a wire tap or vampyre tap if you prefer to connect to the network.
You couldn't just connect anywhere.
You had to connect on these black markings if you wanted a good signal.
And this is how that would look.
Notice this crazy large transceiver.
This is how you would connect to the network.
So to give you an idea of scale, you've got a one dollar US banknote.
So one dollar, he has a British pound.
So notice how big that is.
This is massive cable and really, really old technology.
And it gets worse to actually connect your PC to the network.
You needed a drop cable like this, so you would have to connect that to the transceiver.
And as you can see, it came up there.
This is very thick cabling, not very easy to use.
And that would connect to your network called.
So you would have this kind of setup, that's how you would get onto the network.
It's an absolute nightmare, this cabling very hard to work with.
It was very temperamental.
This is using what's called a bus network.
In a bus network, all the devices are connected on one long cable like this nightmare, I'll demonstrate
this in a separate video where I'll build a 10 base five network and show you one that's working.
But for the moment, just notice how ridiculously difficult this cable is to work with how thick it
is.
This is called thick necked for a good reason because it's so thick.
So after we had thickness lay, then fortunately developed Fernet or 10 based tube.
And if you ever wondered why it's called fenet versus thickness, just noticed the difference in the
size of these cables.
This is the net versus thick net.
This cabling is much, much thinner than this cabling.
But also used a bus typology, also had various issues.
Today, we tend to use UTP so unshielded tries to pay Capling like this, that's very common, or we
use fiber cables and the different types of fiber cables.
I'll talk more about fiber cables later.
We have multimode fiber and single mode fiber.
But the idea is, is that I have a network interface card like this or more modern example like this.
This gets inserted into a computer and this is how I gain access to the network.
A network interface card has a MAC address or media access control address that is essentially a burnt
in address.
Bernstine by the manufacturer that identifies with this network interface card on the Ethernet network.
If you don't have a network interface card in your laptop, you could use a USB to Ethernet adapter
like this.
So that would allow you to connect to the network using Ethernet or once again, using wireless.
Here's an example of a wireless network interface card.
You essentially need a way to get a node onto the network and a network interface card is the way that
you connect yourself to the Ethernet network.
A lot of devices like iPhones as an example, have built in network interface card.
They connect directly onto the wireless and they have something like this built inside of them that
allows them to connect to the wireless network.
Remember, we are transmitting data from one device to another using some kind of media, which could
be the air, could be physical cabling.
