Mesh Topology
                 A mesh topology is just a more advanced ring topology. The mesh topology is one of the most popular corporate
                 settings for a variety of reasons, the most important of which is its reliability. As each node is connected directly to
                 other devices via point-to-point communications, a mesh architecture is extremely dependable. Data traffic will create
                 little to no problems because the gadgets link to other devices on the network.

                 Advantages

                  ÐThe network will not be broken if a single device fails.
                 Ð
                  ÐThere is no traffic congestion because each computer has its own dedicated point-to-point link.
                 Ð
                  ÐFault detection is a simple process.
                 Ð
                  ÐThis topology provides several paths to the destination as well as a great deal of redundancy.
                 Ð
                 Ð ÐIt has a great level of privacy and security.
                 Ð ÐBecause failure does not disturb its processes, data transmission is more consistent.
                 Ð ÐData transmissions will not be disrupted by adding new devices.
                 Ð ÐThis topology can withstand any condition.
                 Disadvantages
                  ÐIt is more expensive than other network topologies such as star, bus, and point-to-point.
                 Ð
                 Ð ÐInstallation is quite costly and tough.
                 Ð ÐThe power need is larger because all nodes must be operational at all times and share the load.

                 Ð ÐA complex procedure.
                 Ð ÐA substantial risk of redundant connections exists.
                 Ð ÐEach node has its own utility cost to consider.
                 Tree Topology

                 As tree topology (also known as hierarchical topology) is ideal for Wide Area Networks, many organisations prefer
                 to utilise it. A root node is required in a tree topology, which connects to sub-root nodes and continues to extend to
                 further nodes as a top-down effect. So, it’s also known as hierarchical topology.
