What is LAN ( Local Area Network )
LAN stands for Local Area Network. This type of network connects computers in the same building or very close to each other. And is considered to be small when compared to the other types of networks. They are in use today such as WAN (Wide Area Network) and MAN (Metropolitan Area Network).
LAN networks operate at speeds ranging from 10 Mbps to 100 Mbps, have low latency, and can transport data over Ethernet cables only (copper-wire based). In this article, we are going to discuss LAN ( Local area network) and the example of LAN.
How do LANs work?
A local area network (LAN) is a computer network that uses any type of medium to connect multiple devices in a small geographic area. The most common types of media used in networks include wired Ethernet, fiber optics, or a combination of both. Typically, LANs connect PCs or network servers within a single building or group of buildings. But there are also instances where LANs connect computers between different buildings, known as campus-wide LANs.
The number of devices connected to your local network will vary by size: For instance, one home may only have one device connected to an Ethernet cable, whereas offices with dozens of employees may require their own dedicated Wi-Fi router for each floor. It all depends on how large your space needs to be and how many people need access at once.
What is a virtual LAN?
A virtual LAN, or VLAN, is a group of devices that appear to be on the same local area network even though they may not be. They function as if connected by a switch, even when connected over different networks. So why does any of that matter to me?
Well, you can use VLANs to create multiple broadcast domains at layer 2 in your network without purchasing new hardware or adding extra equipment. You can also create VLANs across non-routable protocols such as AppleTalk using 802.1q trunking. This allows traffic from one network segment or zone to be isolated from another segment while still being able to talk amongst themselves.
Examples of LAN ( Local Area Network )
Ethernet connects devices via a traditional wired LAN. Typically, Wi-Fi signals are used to create wireless LANs. The most popular networking protocol in modern LANs. Ethernet provides a way to deliver data between two or more connected devices. While it’s not as fast as other protocols, it is quite reliable and cost-effective.
Ethernet can be used to support a local area network. That spans only one building or creates a wide area network with multiple computer systems connected. The original specification for Ethernet was developed in 1973 by Xerox Corporation.
Today, several types of Ethernet exist, such as 802.3i for 10-Mbit/s Ethernet and 802.3u for 100-Mbit/s Fast Ethernet. In addition, other methods of networking have emerged over time. That uses similar functionality but still offers different performance capabilities.
A LAN that uses Wi-Fi for connectivity (either wired or wireless) is called a Wireless LAN (WLAN). A wireless Ethernet network with multiple access points to extend coverage provides scalability. Improved reliability is called an Extended Service Set (ESS). Essentially providing maximum possible bandwidth and access to all nodes at all times.
Common examples of WLANs include hotspots at coffee shops, airports, libraries, corporate intranets, college campuses, hospitals, etc. There can be tens of thousands of clients in WLANs like these.
LAN stands for Local Area Network. A LAN is a computer network that spans a relatively small area. Such as a single building or an entire office complex. WiFi refers to wireless access points that provide wireless connections to LANs.
For example, your phone probably has WiFi connectivity built-in so you can connect wirelessly to WiFi at home, work, public areas like coffee shops and airports, and other local networks.
How Can You Use LAN in Real Life?
A home network (often referred to as a local area network or LAN) refers to a number of devices in one location communicating with each other wirelessly or via cables. Most small businesses and homes use networks because they allow people to share printers, Internet connections, files, and other resources.
They can also be used for more advanced purposes such as video conferencing and gaming. These days, nearly all new PCs come with the wired or wireless capability built-in, which means setting up your own network isn’t too difficult.
Examples of Home Networks
A home network is a set of devices connected to each other through a local area network or LAN. Because it’s your own personal space, you can set up your home network however you want. For example, you could create a home theater setup where all your devices—from PCs to gaming consoles—connect to one wireless router or gateway.
You might also have multiple wireless access points in different rooms of your house for better coverage, so long as they’re all on the same network. But most people just use their home networks for basic stuff like downloading music or sharing printers. Some of them even opt-out entirely when they have internet connections from cable companies or from phone lines that already let them connect multiple computers to high-speed internet service!
