WANs in Organisations Essay1. WHY ARE WANS USED?Wide Area Networks, or WANs as theyre commonly known, ar internets with the efficiency to span quite a distance usually 5 kilometres or more. The main reason for any network usually to forgo the sharing of resources and WANs are no exception to this whether it is sharing resources with an employee of your transaction or a customers business, a WAN will allow data exchanges to be made.They too offer connectivity amid both regional and global sites but differ from the Internet. This is looked at later in this information sheet.WANs allow for centralisation, particularly in administration which is important to allow a good level of control and security.2. engagement DIFFERENCESWIDE AREA NETWORKSWide Area Networks are networks that span a wide field. This is considered to be anything everywhere close to 5km meaning that a several site company will be using a WAN.METROPOLITAN AREA NETWORKSThis is a network that coers between 2km and 5km and is often found in metropolitan cities. These networks are usually owned by a single company but are provided for use by everybody. Occasionally a network much(prenominal) as this will be implemented by a public company such as the local anesthetic council. Generally speaking, a MAN is any type of network that connects computers together in an area of or so 2km 5km.CAMPUS NETWORKSA Campus network is a network of slight than 2km that is operated by a single entity. The buildings connected together may all be owned by the same company, or several companies in this puny area. This type of network is frequently found at university campuses and hospitals. Campus networks usually connect the entire site together to allow the sharing of information.LOCAL AREA NETWORKA LAN is a network that covers a single building. This could include a home network or an office network. It has a range of around 300m.PERSONAL AREA NETWORKThis is any network that is in your immediate area usually a network with a maximum distance of around 15m. It is important to note that this is usually a very simple network that it usually only has a temporary use. Wireless PANs are created by systems such as Bluetooth whilst USB and Firewire are both considered wired PANs when used to directly connect devices to severally other.DistanceLocationUsesWAN5km +Several LocationsConnections private computers together over a large area.MAN2km 5kmSeveral BuildingsPart of a CityConnections between several buildings possibly covering the same area. This could cover an entire city or just a smaller area.Campus2kmSeveral BuildingsUniversity Campus StyleMost used in an area such as a campus. This could be any an actually college/university campus or a group of buildings that require access to each other.LAN 300mHomeA BuildingThis is quite a small area and so is most often found in small business and home type networks.PAN 15mBetween Computer and Phone/PDF/etc.send data such as photos or b ackups between computer and portable devices such as phones.Table showing the distances, location and uses of the basketball team networks.3. WAN AND THE netThe Internet and WANs are two very different things but the majority of WANs will require the Internet, just as the Internet relies of WANs.The Internet is a surplus network that consists of many interconnected networks to provide access to world wide resources and nobody owns it and so nobody merchant ship govern its uses unless other laws are broken.A WAN will have a company controlling it and is therefore much more controlled in who can access and how. A WAN also connects much fewer computers and has a smaller coverage area.4. DEVELOPMENTAL IMPACT ON WANSThere are many things that could impact the development and uses of WAN. The major five are tending, costs, expansion, technology, bandwidth and planning.MAINTENANCEMaintenance is important for any part of a system. Good maintenance will keep the WAN usable whereas no ma intenance will lead to an unusable system.COSTSCosts are an extremely important part of network development. Lower costs means that more things can be changed at once, but costs also impact quality.TECHNOLOGYWANs can only develop at the speed that the technology is developed. At each network based technological breakthrough the support for WANs is increased and improved. If technology does not keep up to speed with the needs of WAN users then the network will not work as effectively as it should.BANDWIDTHBandwidth is very important for the network without it nothing can be sent. If the amount of bandwidth needed by the network exceeds the amount of bandwidth that is available then problems concerning speed and errors are likely to arise. As bandwidth is improved (and the technologies needed to deliver said bandwidth), so are the speeds offered to business for their networks
