What is a LAN (local area network)?

A LAN, or local area network, is a group of devices that connect to a single router. The router provides internet access to all connected devices.

The most common form of LAN is the home network with multiple computers running on Wi-Fi and Ethernet cables—but smartphones and tablets can also use it over Bluetooth or USB connections.

LANs work best when the signal can travel from one device to another without interference from other network networks (for example: if your neighbor has their own Wi-Fi network).

What are The Advantages of LAN?

LANs are a lot less expensive to install and maintain. The cost of connecting each computer on a LAN is much lower than the cost of connecting individual computers using remote modems or ISDN lines.

LANs are faster than WANs because they use shared media, which means all data travels through one cable at once instead of multiple cables or routes as it does in WANs.

LANs are more reliable than WANs because there’s no need for routers. Each computer shares the same connection to the internet, and no single point can fail without taking out all computers connected to it (in theory).

LAN security is easier to maintain because there aren’t any third-party devices involved, and each user has access only to their computer.

This eliminates some significant security vulnerabilities like spoofing attacks on DNS servers or other network services that require authentication from an outside party before granting access rights on your computer or networked device(s).

How Much Does a LAN Cost?

LAN costs vary depending on the size of the network, the number of computers connected to it, and other factors.

The most significant cost is network interface cards (NICs) and cables. While there are many different types of NICs available, they all serve the same primary purpose: providing your computer with an Ethernet connection to communicate with other devices on a LAN.

The price of a NIC depends on its speed and capabilities; you’ll find that some are relatively inexpensive while others can be pretty expensive.

Another consideration when purchasing NICs is whether or not each computer should have its card or share one card across multiple computers—this will save money but might lower performance slightly if too many users try to access files at once.

Once you’ve purchased NICs for each computer in your office, you’ll need to install them by connecting them to each machine’s motherboard via either USB ports or PCI slots, depending on how old/new your machines are.

What Is The Difference Between LAN and WAN?

A LAN (local area network), is a group of computers and other connected devices to share resources.

A WAN (wide area network), on the other hand, covers a larger geographical area and does not have physical connections between all of its nodes.

LANs are usually faster than WANs because they use shorter cables to connect devices. WANs can also be more expensive because they require long-distance telephone lines; this can be offset by using a satellite or fiber optic cable instead of copper wire.

A LAN is generally more reliable than a WAN because there are fewer points where it can fail: only one device or cable may fail at any time rather than many since the connection between each node must be guaranteed for communication over long distances like those involved in satellite use or fiber optic cabling (as opposed to traditional phone lines).

What Is The Difference Between LAN and MAN?

LAN and MAN are similar in that they provide a way to connect multiple computers. The major difference between them is the number of users on each network.

Many people can use a LAN at once, while a MAN can only be used by one or two people at most.

Conclusion

LAN parties are a great way to get together with friends and have fun playing video games. They’re also a great way to test out new gaming hardware and accessories and new games.

You don’t need to be an expert on computers or networking—bring along your computer, some snacks and drinks, and maybe even a game or two that you want to try out at the party.
