NETWORK TOPLOGY

 TOPOLOGY
THERE ARE MANY TYPES OF TOPOLOGIES HERE
SOME OF WHICH ARE BEING LISTED BELOW

TOPOLOGY IS VERY IMPORTANT FOR THE COMPUTER NETWORK WORKING PROPERLY FOR THE CORRECT AND ACCURATE USE OF NETWOR

Network topology is the arrangement of the various elements (linksnodes, etc.) of acomputer[1][2] or biological network.[3] Essentially, it is the topological[4] structure of a network, and may be depicted physically or logically. Physical topology refers to the placement of the network's various components, including device location and cable installation, while logicaltopology shows how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, and/or signal types may differ between two networks, yet their topologies may be identical.
A good example is a local area network (LAN): Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric shape that can be used to describe the physical topology of the network. Conversely, mapping the data flow between the components determines the logical topology of the network.
