What Is A LAN Topology?

What is the purpose of a LAN network?

Local area networks (LANs) are computer networks ranging in size from a few computers in a single office to hundreds or even thousands of devices spread across several buildings.

They function to link computers together and provide shared access to printers, file servers, and other services..

Which is a logical topology?

Logical topology is the arrangement of devices on a computer network and how they communicate with one another. Logical topologies describe how signals act on the network. … The logical topology can be considered isomorphic to the physical topology, as vice versa.

Which topology is difficult to expand?

mesh topologyA mesh topology requires that every device be connected to every other device on the network. It is, therefore, quite difficult to expand a mesh network.

What are the four basic LAN topologies?

13.8 What are the four basic LAN topologies? bus topology, ring topology, mesh topology, and star topology.

What is LAN topology and its types?

Geometric representation of how the computers are connected to each other is known as topology. There are five types of topology – Mesh, Star, Bus, Ring and Hybrid.

What topology are appropriate for LAN?

There are three common topologies found in LANs: star, ring, and bus. In a star topology, all devices on the LAN are interconnected through some central device.

What are 2 logical LAN topologies?

It helps to design the network architecture. It includes information about nodes and switches which are placed in the network. There are majorly two types of logical topology which are bus topology and ring topology.

What topology has no shape?

ringAnswer. A ring. Because it has no end and no starting point like a bus arrangement.

What are the LAN protocols?

Some of the most common LAN protocols are “Ethernet,” “Token Ring” and “Fiber Distributed Data Interface,” or “FDDI.” “Ethernet” is by far the most common type of LAN protocol.

Which topology is best?

A Star Network Topology is best suited for smaller networks and works efficiently when there is limited number of nodes. One has to ensure that the hub or the central node is always working and extra security features should be added to the hub because it s the heart of the network.

What is topology explain?

In networking, topology refers to the layout of a computer network. Topology can be described either physically or logically. Physical topology means the placement of the elements of the network, including the location of the devices or the layout of the cables.

What are the three LAN topologies?

There are three primary LAN topologies: linear bus, ring, and star.

Which topology is used in man?

Metro Ethernet, where a fibre optic ring within a larger city was built as MAN backbone carrying Gigabit Ethernet, became common. The ring topology was implemented using the Internet protocol (IP), so that data could be rerouted if a link was congested or one of the links that was part of the ring failed.

Which topology is best for LAN and why?

Star Star topologyStar topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.
