How does a LAN work?

A local area network (LAN) consists of a series of computers linked together to form a network in a circumscribed location. The computers in a LAN connect to each other via TCP/IP ethernet or Wi-Fi. A LAN is normally exclusive to an organization, such as a school, office, association or church.

What are the limitations of LAN?

A typical LAN technology can span, at most, a few hundred meters. LANs are not designed for long distances. The need for fair access on shared media such as Ethernet and token ring limits the size of a LAN. – CSMA/CD doesn’t work satisfactorily when a network gets too big.

What is the advantage and disadvantage of local area network?

AdvantagesDisadvantagesAllow for much larger and more intricate network Can cover near infinite geographical distanceCost Speed Ease of Use

What is the maximum range of LAN?

The maximum cable length of a twisted pair is 100 m (328 ft.) while for fiber optic cable, the maximum length ranges from 10 km to 70 km, depending on the type of fiber. Depending on the type of twisted pair or fiber optic cables used, data rates today can range from 100 Mbit/s to 10,000 Mbit/s.

Which topology is best?

A full mesh topology provides a connection from each node to every other node on the network. This provides a fully redundant network and is the most reliable of all networks. If any link or node in the network fails, then there will be another path that will allow network traffic to continue.

How much area does a LAN cover?

LANs cover smaller geographical area (Size is limited to a few kilometers) and are privately owned. One can use it for an office building, home, hospital, schools, etc. LAN is easy to design and maintain. A Communication medium used for LAN has twisted pair cables and coaxial cables.

What are the 2 types of LAN networks?

Two Types of Networks: LANs and WANsLocal Area Networks (LANs)Wide Area Networks (WANs)Common uses:File sharingEmail and file transfer (including Web)Common problems:Cable disruption by usersCable disruption by backhoesConceptually:A bunch of lines hooking users togetherA bunch of lines hooking cities together4 more rows•Feb 8, 2012

How does LAN WAN work?

At home, your Local Area Network (LAN) might connect together devices over a distance measured in tens of metres. At work or school, the LAN might connect devices over hundreds of metres. A Wide Area Network (WAN) operates over a much larger area, as they interconnect LANs to allow them to exchange data.

What is the importance of LAN?

Comprising a group of computers and/or mobile devices joined to a server, a local area network (LAN) helps businesses, schools and other organizations conduct daily operations. Setting up a secure and reliable local area network benefits not only you and your employees, but also your customers and business partners.

Which topology is expensive?

Star topologyStar topology is the most popular way to connect a computer in a workgroup. It is expensive due to the cost of the hub. Star topology uses a lot of cables, which makes it the most costly network to set up as you also have to trunk to keep the cables out of harm.

Is Wan faster than LAN?

WAN. LAN, which stands for local area network, and WAN, which stands for wide area network, are two types of networks that allow for interconnectivity between computers. LANs are typically faster and more secure than WANs, but WANs enable more widespread connectivity. …

What devices are needed to form a LAN?

The hardware components of a LAN consist of:PCs/workstations and servers.Network Interface Card (NIC)Cabling and connectors, for example, coaxial cable and BNC connector, Unshielded Twisted Pair (UTP) and RJ-45 connector.Hub, concentrator, and more complicated network devices such as Bridge, LAN Switch and Router.

Do I plug Ethernet into WAN or LAN?

This port is intended to connect your router to the modem, and the outside world from there. The LAN ports are designed for connecting to local devices. Plug one Ethernet cable into your modem and the other end into your router’s WAN port.

What are some of the advantages of LAN?

In LAN computers can exchange data and messages in the easy and fast way. It also saves time and makes our work fast. Every user can share messages and data with any other user on LAN. The user can log in from any computer on the network and access the same data placed on the server.

Which network topology is fastest?

But in mesh topology each devices are connected to other devices directly by individual cables without using center hub. Theoretically the fastest topology should be mesh topology. But the best topology is star topology.

Which network topology is the most secure?

Star TopologyAdvantages of Star Topology Because each of the nodes is independently connected to the central hub, should one go down, the rest of the network will continue functioning unaffected, making the star topology a stable and secure network layout.
