WANs in Organisations Essay Example for Free

pales in Organisations Essay1. WHY ARE WANS USED? round-eyed surface country Networks, or WANs as theyre comm except known, ar internets with the ability to span quite a maintain usually 5 kilometres or much. The main reason for any mesh topology usually to allow the sharing of resources and WANs are no exception to this whether it is sharing resources with an employee of your business or a customers business, a WAN depart allow data exchanges to be made.They also offer connectivity between both regional and global internet sites come throughd differ from the Internet. This is looked at later in this information sheet.WANs allow for centralisation, particularly in administration which is fundamental to allow a good level of control and security.2. NETWORK DIFFERENCESWIDE AREA NETWORKSWide Area Networks are interlockings that span a wide area. This is considered to be anything over around 5km meaning that a several(prenominal) site company will be using a WAN.MET ROPOLITAN AREA NETWORKSThis is a network that covers 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 council. Generally speaking, a MAN is any theatrical role of network that connects computers together in an area of around 2km 5km.CAMPUS NETWORKSA Campus network is a network of less than 2km that is operated by a single entity. The buildings committed together may all be owned by the same company, or several companies in this baseborn area. This type of network is frequently found at university campuses and hospitals. Campus networks usually connect the total 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 wander of around 300m.PERSON AL 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 each other. aloofnessLocationUsesWAN5km + some(prenominal) 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 little area.Campus2kmSeveral BuildingsUniversity Campus StyleMost used in an area such as a campus. This could be either an actually college/university campus or a free radical of buildings that involve 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.Sending data such as photos or backups between computer and portable devices such as phones.Table showing the distances, location and uses of the five networks.3. WAN AND THE INTERNETThe Internet and WANs are two very different things but the studyity of WANs will require the Internet, just as the Internet relies of WANs.The Internet is a special network that consists of many interconnected networks to provide access to world wide resources and nobody owns it and so nobody can govern its uses unless other laws are broken.A WAN will have a company controlling it and is therefore much to a greater extent 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 maintenance, costs, expansion, technology, bandwidth and planning.MAINTENANCEMaintenance is importa nt for any part of a system. Good maintenance will keep the WAN usable whereas no maintenance will lead to an unusable system. beCosts 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 discovery the support for WANs is increased and improved. If technology does not keep up to speed with the needs of WAN users because 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 thusly 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
