What is Network Topology?                              Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network.  It is the topological structure of a network and may be depicted physically or logically. It is an application of graph theory wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. There are 5 types of network topologies: 1.) Linear bus topology                                -is a type of network topology in which each device is connected one after the other in a sequential chain. In this case, the bus is the network connection between the devices, and if any link in the network chain is severed, all network transmission is halted. It works well for small networks because it...

What is a Computer Network?                           A computer network is a  digital   telecommunications network  which allows  nodes  to share resources. In computer networks,  computing devices   exchange data  with each other using connections ( data links ) between nodes. These data links are established over  cable media  such as wires or optic cables, or  wireless media  such as  WiFi . 1. Personal Area Network (PAN)                            -  is a  computer network  for interconnecting devices centered on an individual person's workspace. A PAN provides  data transmission  amongst devices such as  computers ,  smartphones ,  tablets  and  personal digital assistants . PANs can be used for communication amongst the perso...
