Network Topology refers to layout of a network. Network topology specifically refers to the physical layout of the network especially the locations of the computers & how the cable is run between them.
Types of Network Topology
Mesh Topology
Bus Topology
Star Topology
Ring Topology
Tree Topology
Hybrid Topology
Advantages of Mesh topology
Dedicated Links: Dedicated links guarantees that each connection can carry its own data load, thus eliminating the traffic problems that can occur when links must be shared by multiple devices
It is robust. If one link becomes unusable, it does not incapacitate the entire system
It is Secure. When every message travels along a dedicated line, only the intended recipient sees it. Physical boundaries prevent other users from gaining access to messages
Point to Point Connection: Point-to-point links make fault identification and fault isolation easy.
