- 1. Summarize the purpose of a WAN and define what makes up a WAN connection. Detail the types of devices used to establish and maintain a WAN connection and list some of the more common WAN connection methods. Discuss the differences between WAN and LAN connections, and who is responsible for providing WAN connections. Discuss how a modem handles digital information over analog signals. Describe how to configure and setup remote access protocols. What factors need careful consideration? Solution Remote Access Protocols Remote access protocols square measure accustomed management the institution of connections and therefore the transmission of information over WAN links. 3 varieties of remote access protocols square measure supported by Windows Server 2003 remote access: Point-to-Point Protocol (PPP): AN industry-standard set of protocols providing the most effective security, multi-protocol support and ability. Serial Line net Protocol (SLIP): employed by older remote access servers. A Windows Server 2003 RAS server doesn't support SLIP dial-up connections. Microsoft remote access protocol: additionally called Asynchronous NetBEUI (AsyBEUI) and is employed by inheritance remote access purchasers, like Windows NT three.1, Windows for Workgroups, DOS and computer network Manager purchasers. LAN may be a electronic network that connects computers in tiny areas. WAN may be a network that covers a broad space victimization personal or public network transports. The terms {lan|local square measurea network|LAN|computer network} and WAN are usually confusing for those that aren’t that school savvy. These square measure each connections that permit users to attach their laptop to a network, as well as the web. computer network is brief for native space Network, whereas WAN is brief for Wide space Network. These 2 disagree from one another in distinct ways that. computer network may be a electronic network that connects computers in tiny areas like home, office, school, corporation, etc. employing a network media. it's helpful for sharing resources like printers, files, games, etc. A computer network network includes a few of laptop systems connected to every alternative, with one system connected to a router, electronic equipment or AN outlet for net access. The computer network network is made victimization cheap technologies like local area network cables, network adapters and hubs. However, alternative wireless technologies are obtainable to attach the pc through a wireless

The first thriving computer network network was created by Cambridge in 1974 called the Cambridge Ring; but it had been not commercial till 1976 by Datapoint Corporation. Datapoint’s ARCNET was put in at Chase Manhattan Bank in big apple in 1977. the most purpose of making a computer network was to share storage and alternative technologies like printers, scanners, etc. the tiniest computer network will embody 2 computers, whereas the biggest will, in theory, support sixteen million devices per regarding.com. Wikipedia states that “the larger LANs square measure characterised by their use of redundant links with switches victimization the spanning tree protocol to forestall loops, their ability to manage differing traffic varieties via quality of service (QoS), and to segregate traffic with VLANs.” The larger LANs additionally use alternative devices like switches, firewalls, routers, load balancers, and sensors. An analog-digital converter, or ADC because it is a lot of unremarkably referred to as, may be a device that converts analog signals into digital signals. Analog data is transmitted by modulating a continual transmission signal by amplifying a signal's strength or variable its frequency to feature or deduct knowledge. Digital data describes any system supported discontinuous
- 3. knowledge or events. Computers, that handle knowledge in digital kind, need analog-to-digital converters to show signals from analog to digital before it are often scan. One example may be a electronic equipment that turns signals from digital to analog before sending those signals over communication lines like phonephone lines that carry solely analog signals. The signals square measure turned back to digital kind (demodulated) at the receiving finish so the pc will method the information in its digital format.
