Question: Which Topology Is Highest Reliability?

What is the most common topology?

Here’s a brief overview of each:Star topology is by far the most common network topology.

Bus topology—also known as line topology or backbone topology—connects all devices via a single cable running in one direction.

Ring topology, as its name suggests, features all nodes arranged in a ring.More items…•.

What is a LAN topology?

Topology is the physical and logical arrangement of a network. The logical arrangement of a network refers to how the workstations, servers, and other equipment relate to each other in terms of traffic flow. … There are three primary LAN topologies: linear bus, ring, and star.

What is hub topology?

In network science, a hub is a node with a number of links that greatly exceeds the average. … Hubs have a significant impact on the network topology. Hubs can be found in many real networks, such as the brain or the Internet.

Is mesh topology highly reliable?

Mesh topology is inherently reliable and redundant, and can be expanded quickly. … Networks can be deliberately over-designed for reliability by adding extra nodes; typical mesh networks can expand to hundreds or even thousands of nodes.

How many topology are there?

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 is the world’s largest network?

The InternetThe Internet is the world’s largest computer network.

Where is star topology used?

Star Network Topology Star network topologies are common in home networks, where the central connection point may be a router, switch, or network hub. Unshielded Twisted Pair (UTP) Ethernet cabling is typically used to connect devices to the hub, though coaxial cable or optical fiber may also be employed.

What is multipoint topology?

Multipoint connection is used in BUS Topology. All the devices are connected to a single transmission medium, which acts as the Backbone of the connection. This links all the devices in the network. Here each node has its unique address.

Which topology is required?

Which topology requires a central controller or hub ? Explanation : Star topology and tree topology requires central controller or hub. Mesh, ring, bus topologies doesn’t need hubs.

Which of the following has highest reliability?

The topology with highest reliability is:A. Bus topology.Star topology.Ring topology.Mesh topology.

Which topology is not commonly used as it is expensive?

This topology is not commonly used for most computer networks as it is difficult and expensive to have redundant connection to every computer. However, this topology is commonly used for wireless networks. Below is a visual example of a simple computer setup on a network using a mesh topology.

Which topology is highly expensive?

Full Mesh: All the devices are directly connected to all the other devices in the network. Therefore it provides fill redundancy and is also the most expensive of all the topologies as it requires multiple NIC’s and cables for each node. This scenario is often found in the WAN’s (Wide Area Network).

What is star bus topology?

Star Bus is a networking topology in which hubs for workgroups or departmental local area networks (LANs) are connected by using a network bus to form a single network. Star bus topology is a combination of star topology superimposed on a backbone bus topology. … Crossover cables for regular (host) ports on the hub.

Why is ring topology used?

In wide area networks (WAN) and meteropolitan area networks (MAN), a ring topology is used to as the topology for the backbone (sometimes called a city ring) to connect the customers. In that case the ring is used in both directions to have two distinctive paths to the public switch.

Which topology has the highest maintenance?

Mesh TopologyThe Mesh Topology This type of network topology boasts the highest fault tolerance of all of the network topologies, it is also usually the most expensive.

What is topology diagram?

A network topology diagram shows how the elements of a computer network are arranged. It allows you to visualize how different nodes are connected and how they communicate.

What is hybrid topology?

Hybrid topology is an integration of two or more different topologies to form a resultant topology which has many advantages (as well as disadvantages) of all the constituent basic topologies rather than having characteristics of one specific topology.

Which 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 topology is best Why give reasons?

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.

Why do we use topology?

Topology lets us talk about the notion of closeness (i.e., neighborhoods), which in turn allows us to talk about things such as continuity, convergence, compactness, and connectedness without the notion of a distance. So, topology generalizes fundamental concepts of analysis/calculus.

Which of the following topologies has the highest reliability?

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.
