a long info about uses of star topology
Answers
Answer:
A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down. Star topology.
Star topology is used to ease the probabilities of network failure by connecting all of the systems to a central node. This central hub rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, sometimes including the originating node.
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.
Star Topology is the defacto topology for most networks you will encounter. It allows end points to be connected to a central device. As for its use? It can be used for virtually anything as it is very flexible. Any single node that fails typically only effects that node.
Unless you are connecting large switches together in a specific way or doing something very specific your topologies will be stars. Sometimes stars that branch off other stars but still
A star topology is designed with each node (like workstations, printers, laptops, servers etc.) connected directly to a central device called as a network switch. Each workstation has a cable that goes from its network interface card (NIC) to a network switch.
Advantages of Star Topology
• Easy to install and wire.
• No disruptions to the network when connecting or removing devices.
• Easy to detect faults and to remove parts.
Disadvantages of Star Topology
• Requires more cable length than a linear bus topology.
• If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in computer network communication.
• More expensive than linear bus topology because of the cost of the connecting devices (network switches).
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.
Answer:
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.
