INTRODUCTIONIn recent times the way of communication is changing. It is because of change ininfrastructure due to technological advancement. With this there is increase in speed ofcommunication. Now, broadband is used instead of power lines. It is a method in which data istransmitted at fast rate and to wider frequency (Arioua and et.al., 2016). This technologyprovides high rate transmission to long distance. The BPL technology is similar to PLC one. Inthis report it is described about network technology and its relationship between components.Also, issues related to the technology are discussed. Moreover, network principles are explainedalong with legislation, regulation, security, etc. of use of network technology.APPLICATION AND ANALYSISA network is build up of various components which are connected to different devices. Itallows to share data and information from one device to another. Network technology is referredas exchange of data between large information systems. For this there are various typestechnology available through which network is created. With change in time the technology isalso advancing. Basically, there are two types of networking technologies. They are wired andwireless. In that also different concepts and methods exits. Routers can be used to connectnetwork. It is a small device that is used to forward data packets between computer network.Routers also manage traffic and then direct data packets in right direction.Optical fibre is another wireless technology that is used in network. Here, glass and plastic isused to transmit data (Optical fibre in networking.2016). It is having a high range and frequencyvary from 10-100 GBPS. Also, the cable is covered from copper which protect it from anyelectromagnetic interference. This makes its signal strength is strong.There are various components in network such as hub, router, switch, gateway, etc. eachcomponent functions are different (Menon, Pathrose and Priya, 2016). These all create an entirenetwork. A hub connects devices in LAN whereas a gateway is a stopping point of data. So,these all components are interrelated to each other. For instance, a hub is connected to routerwhich gives direction to data packet. Furthermore, a router is connected to switch to which datatransfers. In network a firewall protects threats and unauthorised access. It provides security tonetwork by protecting virus.In network there are certain principles which are followed. Along with it, some definedprotocols are used. A network works on OSI model in which there are many layers. It starts from1
