Topology

Topology is a layout of computers and devices in a Network. They are bus, star, mesh, ring, hybrid.

Bus 

• This layout connects devices to a main line called a backbone. 

• This backbone can be a coaxial line or an Ethernet line.

• The single cable, where all data is transmitted between devices, is referred to as the bus, backbone, or trunk.

Star 

 • In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. 

• A type of network topology in which every device in the network is individually connected to a central node, known as the switch or hub.

Mesh 

• Mesh topology is a type of network topology in which all devices in the network are interconnected. In a mesh topology, data can be transmitted by routing (sent the shortest distance) and flooding (sent to all devices). 

Ring 

each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node – a ring. 

Hybrid 

• hybrid topology is the combination of two or more networks. The network type could be Star, Ring, Bus, or Mesh.

• However, in most cases, only the Star and Ring topologies are used to create a Hybrid network.
