Computer Network: An interconnection of multiple devices, also known as hosts, that are connected using multiple paths for the purpose of sending/receiving data or media. Computer networks can also include multiple devices/mediums which help in the communication between two different devices; these are known as Network devices and include things such as routers, switches, hubs, and bridges. The arrangement of a network that comprises nodes and connecting lines via sender and receiver is referred to as network topology. The various network topologies are: a) Mesh Topology : In a mesh topology, every device is connected to another device via a particular channel. Figure 1: Every device is connected with another via dedicated channels. These channels are known as links. Advantages of this topology : 1.It is robust. 2.The fault is diagnosed easily. Data is reliable because data is transferred among the devices through dedicated channels or links. 3.Provides securi...
