Networking Technologies 4INTRODUCTIONA network can be said as a group of computers sharing data and information witheach other using a data link. The computers on which sharing is being done are called nodes.Networking Technologies are some mediums that helps in connecting with people lackinggeographical restrictions. These systems offer an easy way to share files. Also it provesbeneficial for resource sharing as devices like printers, modems, scanners can be shared overall the computers in the network. These technologies gives flexible access to people asaccessing files from systems throughout the network is allowed. Some common types ofnetwork consists of LAN ( Local Area Network), WAN ( Wireless LAN), PAN(PersonalArea Network) etc. The Beta Communication Ltd is a telecommunication company that dealsin telecom products. This report is about designing and implementing LAN in the BetaCommunication Ltd. TASK 11.1 Types and Topologies of Networking SystemsAs a Network Consultant, it is important to have a deep knowledge of all the types ofnetwork because any customer can request for a different network any time depending on hiswork schedules and lifestyle. Some common types of network are:1.Local Area Network (LAN) – LAN connects various network computers over shortdistances. This connection can establish in buildings, schools, hostels or any placewhere devices can connect over short distance (Luehmann and Tinelli, 2008). It canalso be said as a group of computers sharing a same communication line. Benefits: We can send e-mails between different nodes.Centrally management of all the nodes attached is easy.Communication through a LAN network is cheaper than the other networks.The data is stored on the server computer which makes it more secure.The same internet connection is served among all the users connected to the LAN.
Networking Technologies 5Limitations: Less chance to move in a different location.Server maintenance is expensive. The set up cost used in the implementation and thenmaintenance of a LAN is quite expensive (Burgess, 2009).This connection only covers a limited area as it covers short distances.The LAN administrator has permissions to check the files on any computer connectedto the server any time and somewhere it violates users privacy (Luehmann and Tinelli,2008).A LAN administrator is always required as if sometime errors or any problems attackthe system, the administrator can solve it. His/her absence can lead to a huge loss oftime which can affect the company as well.
Networking Technologies 6(Source :Antsaklis and Baillieul,2004 )As we can see in the picture above, all the servers i.e. file server, mail server, any outputdevice say printer and all the nodes are connected over a single communication line.2.Wide Area Network (WAN) – A WAN is a network in which connected nodes maybe far apart i.e. within a radius of 1 Km. The biggest example of a WAN is Internetwhich is covering the whole earth. It is a collection of various LANs connectedtogether. The connection between a LAN and a WAN is established by a router. AVPN i.e. Virtual private network eases the connection between different WANs. Theseconnections can be wired as well as wireless. 4G which is in a huge demandnowadays, comes under wireless WAN technology.Benefits:Increase in bandwidth as in this network, leased lines are used instead of broadbandwhich gives high upload speed (Antsaklis and Baillieul, 2004).Illustration 1: Local Area Network
Networking Technologies 7IT infrastructure is centralised.It helps in sharing data within all the sites without sharing it over internet, whichboosts a user's privacy.ISDN i.e. Integrated Services Digital Network, can be eliminated from WANs as theydon't need ISDN for calls etc.Limitations:Security Issues are being faced sometimes in this type of network.Issues in maintenance Setup cost of a WAN is higher than other networks as WANs are quite complicated.Maintaining a WAN is also not easy, it causes issues sometimes, which take time to besolved.(Source: )3.Personal Area Network (PAN) – A PAN connects different nodes within a person'spersonal habitat, within a range of 10 metres. It has some advantages but someIllustration 1: Wide Area Network
Networking Technologies 8disadvantages too. It is handy and safe but sometimes have a slow speed for datatransfer. Explaining with an example, If a person is travelling along with his tablet, aPDA( personal digital assistant) and a printer that is portable, he can interconnectthem without any plug-in and take the output as well (Burgess, 2009). This makesPAN different from other networks.Benefits:There are no security issues in this network because it is limited to a very small area.A PAN network is movable. It is easy to move this network from one place to another.It can be established either wirelessly or by cables (Luehmann and Tinelli, 2008).Less technical skills required than the other networks because it is less complicated.Easy and simple to set up a PAN network.Limitations:Instead it's simple to implement a PAN network but it is costly to use.It has a small Range of 10 metres only.Transmission speed is not so high in PAN. It is moderate.In this network, sometimes there are compatibility issues because WPAN techniquesare usually not compatible with each other.
