Mesh network: Each node must strive to be connected to every other node in the system. Star network: A central node server is linked to multiple other nodes. This is faster since data doesn’t have to travel through each node. Tree network: Here, nodes are arranged in hierarchies. 2. Document & update constantlyRouters figure out the fastest data path between devices connected on a network, and then send data along these paths. To do this, routers use what's called a "metric value," or preference number. If a router has the choice of two routes to the same location, it will choose the path with the lowest metric. The metrics are stored in a routing table.Layer 2 Switch: A layer 2 switch is a type of network switch or device that works on the data link layer (OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded.
