Network Topology

A network topology is the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical topology.
Topology that consist of devices and wire, which seems physically how network is connected is called Physical topology but Logical or Loopfree topology how how actual data is transmitted over physical topology.

Types of Network Topology

1. Bus Topology: A bus network is a network topology in which nodes are directly connected to a common linear half-duplex link called a bus.
 Bus Topology
2. Ring Topology: A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring.
 Ring Topology
3. Star Topology: A star network is a network topology consists of one central node, typically a switch or hub, which acts as a conduct to transmit messages.

4. Mesh Topology: a star network consists of one central node, typically a switch or hub, which acts as a conduct to transmit messages or can say all nodes are connected to each other.
