name the four types of topologies describe all of them
Answers
Answer:
Star topology – all computers and devices are connected to a main hub or switch. The hub or switch amasses and disburses the flow of data within the network. Star topology is the most common type of network and follows the Ethernet standard.
Bus topology – in this arrangement computers and devices are connected to a single linear cable called a trunk. The trunk is also referred to as the backbone or a segment. Each end of the trunk must be discharged to prevent the signal from rebounding back up the cable.
Ring topology – computers and devices are connected to a closed loop cable. Here there are no terminating ends so if one system crashes the entire network goes down. Each computer functions as a repeater and charges the signal before sending it to the next station.
In Ring topology data is sent through the network by way of a token. If the token isn’t carrying any data, a computer waiting to send data seizes it, attaches the data and the electronic address to the token and sends it on. Once the token is received by the destination computer it strips the data and the token is sent on. This is why it’s named a token ring network.
Mesh Topology :
In mesh topology, every device is connected to another device via particular channel.
Answer:
The mapping of a LAN design is called Topology. There are four categories: Star topology, Bus topology, Ring topology and Mesh topology. Hybrid combinations of these topologies also exist.

Mesh Topology-A mesh network (or simply meshnet) is a local network topology in which the infrastructure nodes (i.e. bridges, switches, and other infrastructure devices) connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data from/to clients. This lack of dependency on one node allows for every node to participate in the relay of information. Mesh networks dynamically self-organize and self-configure, which can reduce installation overhead. The ability to self-configure enables dynamic distribution of workloads, particularly in the event a few nodes should fail. This in turn contributes to fault-tolerance and reduced maintenance costs
