What is network topology and Explain its types?
Network Topology
Network topology is the study of the arrangement or mapping of the weather (links, nodes, etc.) of a network, especially the physical (real) and logical (virtual) interconnections between nodes of a networks.
A local area network (LAN) is one example of a network topology that exhibits both a physical topology and a logical topology. Basic types of Topologies
The arrangement or mapping of the weather of a network gives rise to certain basic topologies which can then be combined to make more complex topologies (hybrid topologies).The most common of those basic type sorts of topology are:
BUS (Linear Bus, Distributed Bus) Topology Star Topology Ring Topology Mesh Network Topology Partially connected mesh (or simply ‘mesh’) Fully connected mesh Tree Topology Hybrid Topology Point to Point Topology
Star Topology
In Star topology each device (node) is physically connected with central controller known as hub or switch, each device has a dedicated point devices are not directly connected with one another.
A Star Topology is designed with each node (file server, workstations, and peripherals) connected directly to a central Network Topology hub or concentrator.
Data on a Star Topology passes through the hub or concentrator before continuing to its destination. The hub or concentrator manages and controls all functions of the Network Topology. It also acts as a repeater for the info flow. This configuration is common with twisted pair cable; however, it also can be used with coax or fiber optic cable. The protocols used with star configurations are usually Ethernet or Local Talk. Token Ring uses an identical topology, called The Star-Wired Ring.
