Masters of Health Informatics2Answer to question no-1: WANWide Area Network connects several local area networks (LAN) to one other over alarge scale network. Speed of transferring the data depends on the cost of connection whichfuture depends on the distance of the router. WAN are not managed or controlled by a singleentity these are retained by distributed ownership. Wired network area allows end user toaccess the application, services that are centrally located (Nobre, Mozzaquatro & Granville,2018). This provides secured transmission of data packet over network and WAN doesn’trequire installing same application on multiple resources.WAN is like banking system, where several different remote branches are connectedover a network to share their official data (Nafi, Ahmed, Gregory & Datta, 2018). Internet isthe largest Wide Area Network in the domain. Various WAN networks are available, someare:Circuit Switching – Circuit switching is mostly used in dialup connections bycreating a path in the network so that synchronous communication can take place betweenend points.In this bit delay is constant and provides continuous data transfer withoutoverhead. Example: Optical mesh network, cellular network.Packet Switching is done by dividing the data into smaller packets and transmitting itover network. Bandwidth is pooled among the nodes. It has a high speed for transferring thedata packets. It may sometimes cause indefinite transfer delayIntegrated Services Digital Network(ISDN)- It is based on synchronous, bitoriented data transfer basically designed for transmission of digital voice, video overnetwork. It is useful for video conferencing from remote areas.

Masters of Health Informatics3Asynchronous Transfer Mode- It provides functionality of both packet switchingand circuit switching. It uses connection oriented approach and establishes virtual circuitbefore actual exchange of data packets. It is globally available and least expensive also usesVPN technology for strong security.Answer to question no-2: Types of WANDifferent Types of WAN and their basic structure or configurationFrame Relay: It is a wide area network that handles the communication between datapackets over a frequently changing path. It is extremely simple to implement and lessexpensive. It connects to remote LANs via virtual circuits and once the packets reaches to thedestination it is charged according to its usage.It puts the data packets in variable size frames and leaves the less important packets,by prioritizing important frames and creating others as less significant.Basis Structure of frame relayFigure 1: Basic structure of frame relay
