Network Topologies

network topologies

Network topologies are the patterns of computers in the network. It is the physical layout of the terminals, links and computers in the network. Network topologies are several types. Some topologies used in LAN are as follows:

  • Bus or linear topology
  • Star topology
  • Ring topology
  • Mesh topology
  • Hybrid topology

Bus or linear topology

Bus Topology

In this topology, all the computers are connected to a common cable called the trunk. Its every end has a terminator and the terminator stops the flow of data out of bus. In this network, if the cable breaks it affects the whole network. There is a maximum chance of collision of data.

Star Topology

Star Topology

In this topology, all the computers are connected to a master computer called server. In this type of network, the server controls all the other computers. This is the most commonly used topology in LAN. In this network, if the central point (server) fails, the whole network fails but the failure of one computer doesn’t affect the rest of the network. There is no chance of data collision.

Ring Topology

Ring Topology

In this topology, one computer is connected with other, and so on to form a ring pattern. There is no master computer to control data communication in the ring topology. This network provides equal access for all computers so, of one of the computers fails, it impacts all the computers in the network. There is no chance of data collision.

 

Mesh Topology

Mesh topology

In this topology, all the computers are connected to each other and form a mesh. It is a completely connected network. It is more reliable because if anyone connection breaks down, it will not affect other computers. But more cables are required to form this topology. So, it is expensive to implement.

Hybrid Topology

Hybrid topology

This topology is the combination of all the topologies. In this topology, bus topology, ring topology, and star topology are combined to get a better result. Some standard hybrid topologies are star bus and ring.
