>> Welcome to Lesson 4.3, Network Interface Cards.
00:00
We're going to still continue our talk on
00:00
expansion cards connected to
00:00
your system for advanced capability.
00:00
Let's go ahead and get started.
00:00
For this lesson, we're going
00:00
to discuss network interface cards.
00:00
We're going to talk about ethernet and gigabit cards,
00:00
wireless and fiber optic.
00:00
Network interface cards.
00:00
Network interface cards, or NIC cards,
00:00
as they're commonly known,
00:00
are a type of expansion card that
00:00
provides connectivity to a network,
00:00
thus the name network interface card.
00:00
A network interface card or network interface connection
00:00
generally started out with
00:00
the 10/100 speed cards and moved up to gigabit.
00:00
These are standard for a desktop,
00:00
primarily computer and in
00:00
laptops up until the current models.
00:00
In the newer current model of laptops,
00:00
they're starting to be made without
00:00
a network interface connection.
00:00
You'd have to use an adapter through
00:00
USB or any other type of connection.
00:00
But network interface cards is a standard of connecting
00:00
to your desktop or your mobile device to a network.
00:00
Now, let's talk about throughput speeds,
00:00
because there's a variety of speeds that
00:00
these cards came in and come in right now.
00:00
Originally, the 10/100 megabytes speeds
00:00
were available in those cards,
00:00
was on either 10 or 100 megabit connection
00:00
provides you connectivity to the network.
00:00
As time went on,
00:00
this one up two gigabit speeds
00:00
and cards came out with gigabit speeds.
00:00
You can get gigabit speeds in
00:00
your mobile device or your desktop PC.
00:00
Now currently we're up to
00:00
2.5 gig and 10 gig speeds in network interface cards.
00:00
You can't have an expansion card up to
00:00
those speeds depending on
00:00
the application that you need to use that system for.
00:00
Wireless interface cards.
00:00
Wireless interface cards provides
00:00
wireless connectivity through an expansion add-on card.
00:00
Again, same way we talked before as far
00:00
as they installed right through the PCIe slots.
00:00
This card gives you
00:00
wireless connectivity versus the wire connection.
00:00
Applications here would be mobile PCs, wire connections.
00:00
That's impractical and not
00:00
possible for wired connections.
00:00
Or you're in an environment
00:00
where a wire connection will not be proper,
00:00
you use the wireless card.
00:00
Fiber optic interface cards provides
00:00
connectivity through a fiber optic interface.
00:00
Applications here will be
00:00
high throughput applications or data center environments.
00:00
You will see a fiber optic connections
00:00
in the back of servers,
00:00
high-end data processes stations,
00:00
and even some environments workstations have
00:00
fiber-optic expansion cards
00:00
installed in the back of them.
00:00
Again, for those higher throughput applications,
00:00
these come in a variety of
00:00
different makes through different vendors.
00:00
You'll see a lot of these on the market and they even
00:00
use quite steadily throughout the years.
00:00
This was a brief review of network interface cards.
00:00
Primarily we talked about
00:00
ethernet and gigabit ethernet cards,
00:00
wireless cards, and fiber optic cards.
00:00
Those are the network interface cards
00:00
that you would be seeing on the CompTIA.
00:00
We will see you in the next lesson.
