this is less than 13.6 network types, and this lesson, we're gonna talk about different types of networks. So let's go and get started.
In this lesson. We're gonna talk about different network types, types of networks that you're going to encounter during the A plus as well as in the real world. And when you in your role as a technician or with other feel that you may go into helping customers with their networks now is different type of networks. When we traditionally
think of a network, we think of a land. But there's more networks. The Net.
So let's have a look at these different type of networks.
The first network we're gonna look at is a land ah, Land is a local area network.
A land or local area network is comprised of network devices within a building, a group of buildings or even a campus. The devices are relatively close in proximity, so if you have an office, small office or even a whole, these devices are again
and close in proximity within the same floor with several floors, or it could be many floors,
but they're within close proximity, not across the the town or across the world or across the country. They're relatively grouped together within the same geological location, a building or a couple of buildings, high speed connectivity through the land, connections that they provide.
As you all know that we've studied before.
Network connections are either 10 100 or even one gigabit wired or wireless, meaning the devices connect be connected through a traditional copper twisted pair
or wireless devices or a mix of both. But a local area network is generally gonna be devices within close proximity of one another. Several rooms across next door, next building within the same office building or couple office buildings again just want to reiterate that
Ah lan, a wide area network. So let's look at what a wide area network ISS. It covers a bigger area. Remote locations regionally around the world. Now this connects our way in, connects multiple lands. Many different types of land technologies can provide a connection between these different lands.
It could be email us NPLs, fiber. There's other connective visas. Well,
so picture this. If we have a LAN a wide area text, it could be your traditional networks within an office location a that's in California and another location. It's in New York or Boston, and they're connected through either leased lines or other forms of Internet connection types
that forms a whan, a wide area network.
Same premise as a land but geographically further away. Now let's look at what a man is. A man is a metropolitan area network. Now. A man is a midpoint between the land and the land, so let's gonna discuss what that really means now. Sometimes they could be managed by a central provider,
multiple lands tied together through a backbone connection,
and also these will refer to as campus networks. That reference is not really used a lot today. Years back, they were reference as campus networks. So in between the land and the land, you could have a group of buildings on one part of a location or town
and across town, another group of buildings.
But the key thing is they're tied together through the same Internet or central provider, providing that backbone connective ity. Sometimes a provider would give you a service where you can connect your buildings of your locations together using a centralized backbone, so you're connected to the provider's network
through a least line. Copper are or fiber,
but you are connected again to your own physical network, like a land but bigger than a lands. And it's called a man, a metropolitan area network.
Now let's talk about some other types of networks where some of these networks you may not even consider to be networks, but theoretically they are an is a personal area network. A Pain is a personal area network created by personal wireless device connections, Bluetooth I R. Or in F CES,
mobile phones and wireless headsets. All those are pans your personal area network. You may not think that when you're on your phone and you have your phone in your Bluetooth earbuds in or your headset that you've created a pan, a personal area network where you have
your personal device connected to another person, dice
just for you and you're the only user within that network. So that's a pan. Now let's look at a W M. In network or wireless mesh network. Ah, wireless Mesh network is a newer type of network that a sin around I'll T devices Internet of Thing devices
devices are connected through wireless. They form a mesh cloud of devices.
And with the mesh cloud. Usually there may be multiple wireless points that will create a healing factor. If one access point is down, are off line. Another access point will pick that up. Generally, if we have multiple access points, it will create that type of healing factor. Um, and also redundancy.
So I ot devices could be a little bit of anything that we've traditionally begin to start using. Now
thermostats, security cameras off those things. Those I o t devices.
Okay, that's a lesson for today. We talked about different networks. We talked about the land the way in the man, the pan and the W. M. In networks. These are all different type of networks that you encounter on the A plus.
So that's it for this lesson. We will see you in the next lesson.
