What is Star topology? The expanded star should retain the advantages of the star, and by sub-division of the network the cost of each switch is lowered and each star can be serviced without total network interruption. The system already has too many switches, so no cost to start, just new cabling. A hub maybe a hub, a router or a switch. In star Topology, there exists a point-to-point connection between a node and hub device. The hub device takes a signal from any node and passes it to all the other nodes in the network.
Jun 04, 2020 A logical network topology is a conceptual representation of how devices operate at particular layers of abstraction. A physical topology details how devices are physically connected. Logical and physical topologies can both be represented as visual diagrams. A network topology map is a map that allows an administrator to see the physical network layout of connected devices. Star topology is cost-effective to some extent, while the mesh is expensive. The star topology has a drawback where the inoperative central hub can make the entire system inoperative. On the contrary, the mesh topology is more robust than the star topology. Star topology only uses twisted pair cable as a transmission media.
Star Topology
Fallout 1 fixt mod. Star Topology is the most common type of network topology that is used in homes and offices. In the Star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch. In a Star Network the best advantage is when there is a failure in cable then only one computer might get affected and not the entire network.
May 12, 2019 Most popular and widely used LAN technology Ethernet currently operates in Star Topology. Main disadvantages of star topology are:. Too much dependency on a central device has its own drawbacks. The flash skyrim mod. If it fails the whole network goes down.

Prerequisite – Network Topologies
Star Topology:
In Star topology, the nodes are connected to the central hub or router in which the information is travel from central hub or router to all the nodes. There are n links in Star topology, if there are n nodes. The nodes are connected to each other completely via dedicated link in which the information is travel from nodes to nodes.

Mesh Topology:
In Mesh topology, the nodes are connected to each other completely via dedicated link in which the information is travel from nodes to nodes and there are N(N-1)/2 links in Mesh topology, if there are N nodes.

Difference between Star and Mesh Topology:
S.NO | Star Topology | Mesh Topology |
---|---|---|
1. | In star topology, the nodes are connected to the central hub or router. | In mesh topology, the nodes are connected to each other completely via dedicated link. |
2. | There are N links in Star topology, if there are N nodes. | There are N(N-1)/2 links in Mesh topology, if there are N nodes. |
3. | The cost of Star topology is less. | The cost of Mesh topology is expensive. |
4. | The complexity of Star topology is quite simple. | The complexity of Mesh topology is complex. |
5. | In star topology, the information is travel from central hub or router to all the nodes. | In mesh topology, the information is travel from nodes to nodes. |
6. | Star topology is very good extensible. | Mesh topology is poor extensible. |
7. | In star topology, twisted pair cable is used for connection. | In mesh topology, twisted pair cable, coaxial cable and optical fiber cable are used for connection on the basis of type of networks. |
8. | Star topology is used in LAN as setup is easy. | Mesh topology is used in WAN. |
