Those of you who you are not familiar with, the network interface card probably want to be at this
point, so here goes a network interface card and I see it installed in your computer to connect or
interface your computer to the network.
It provides the physical, electrical, electronic connections to the network media.
The network interface card is a layer to two device.
That is, it works at the datalink.
Clear that you do remember we have seen the detail in clear in the model.
Right?
So the network interface card is known as a little device because the information it uses for communication,
the MAC address it resides on Datalink, a network interface card is either an expansion card or is
built right into the computer's motherboard.
Today, almost all indices are built into the computer motherboard, providing a speed of around 1000
megabits per second.
Well, make sure that this is megabits per second and not megabytes per second.
We have seen the differences in earlier sections.
Nowadays, most PCs and laptops of all types come with an Internet and wireless connector built into
the motherboard.
So you usually do not need a separate interface card.
Uh, it's rare to find a laptop today without a built in wireless network card, but you can buy an
external wireless card for next stops and laptops if you've got the legacy equipment that needs them.
So long story short, in short, you need to just remember that a network interface card is a kind of
a chip which is installed in your computer that allows you to connect your computer to the network.
Now, how this works and how this allows us to connect is not a part of the basic fundamentals of computer
networking.
It's it goes more into electronics.
You just have to remember the functioning of the network interface card that it is used to connect your
PC to the wireless network.
The next lecture, we will talk about an interesting device known as The Hub.
You have heard how many times from me.
So in the next lecture, we will explore what the hub actually is.
