Which Of The Following Has Highest Reliability?

Which topology has the toughest fault identification.

Explanation: In the bus topology, fault identification is tougher..

What is the advantages and disadvantages of ring topology?

Due to the Uni-directional Ring, a data packet (token) must have to pass through all the nodes. If one workstation shuts down, it affects whole network or if a node goes down entire network goes down. It is slower in performance as compared to the bus topology.

Star TopologyWhat Is Star Topology? A star topology, the most common network topology, is laid out so every node in the network is directly connected to one central hub via coaxial, twisted-pair, or fiber-optic cable.

What is topology and 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.

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.

Which topology is backbone present?

In Bus backbone the topology used for the backbone is bus topology. In above the Bus backbone structure is used as a distribution backbone for connecting different buildings in an organization.

Is mesh better than router?

Mesh WiFi systems are basically the same as regular routers and extenders, but they’re a lot smarter and work a lot better. … And they look better than traditional routers and extenders, which may encourage you to keep them out in the open instead of a closet, where WiFi signals can get muffled.

Is mesh WiFi better than extender?

Mesh Network Systems Are More Seamless, Efficient, and Quick to Update. Unlike an extender, which you can add to an existing Wi-Fi network, mesh systems are typically complete replacements for your home Wi-Fi.

Which topology is best for LAN?

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.

What is advantage and disadvantage of star topology?

The disadvantages of a star network are: it is expensive to install as this type of network uses the most cable (network cable is expensive) extra hardware is required (hubs or switches) which adds to cost. if a hub or switch fails, all the devices connected to it will have no network connection.

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.

What are the disadvantages of a mesh network?

Disadvantages Of A Mesh TopologyComplexity. Each node needs to both send messages as well as act as a router, which causes the complexity of each node to go up pretty significantly. … Network Planning. … Latency. … Power Consumption.

Which network is the smallest?

Personal Area NetworkPersonal Area Network (PAN) The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building.

Which cable is used in star topology?

The failure of a transmission line linking any host to the hub will result in the isolation of that host from all others, but the rest of the network will be unaffected. The star configuration is commonly used with twisted pair cable and optical fiber cable. However, it can also be used with coaxial cable.

What is topology explain?

A Network Topology is the arrangement with which computer systems or network devices are connected to each other. Topologies may define both physical and logical aspect of the 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 star topology is more reliable?

Star topology is used to ease the probabilities of network failure by connecting all of the systems to a central node. … In contrast to the bus topology, the star topology allows each machine on the network to have a point to point connection to the central hub and there is no single point of failure.

What is the cheapest topology?

The star and extended star are the most popular topologies for Ethernet networks. This type network is easy to setup, relatively inexpensive, and provides more redundancy than other topologies, i.e. bus topology. The star topology is configured by connecting all of the nodes on the network to central device.

Does mesh network reduce speed?

The main downside of a mesh network is that you lose some speed with every so-called hop. … Netgear’s Orbi works differently than traditional mesh systems. It has a dedicated Wi-Fi band, or connection, in which only the router and satellites can talk to each other; no other devices can interfere with their connection.

Which topology has highest reliability?

Mesh topologyMesh topology can handle high amounts of traffic, because multiple devices can transmit data simultaneously. A failure of one device does not cause a break in the network or transmission of data.

Who invented network topology?

Howard (Howie) Frank. Frank had founded Network Analysis Corporation (NAC), a company specializing in topological design based on his groundbreaking work at the Office of Emergency Preparedness (OEP). Frank remembers Roberts’ call requesting a meeting: “Arpanet was a four node network.
