Different Networking Systems Advantages and Disadvantages

Different Net fixing organisations Advantages and DisadvantagesLocal Area profits Local Area electronic network is isolated network. Gener eithery, It is build in a sensible location. such as office, home etc. Computers argon colligateed to all(prenominal) different by a small server and also connected to the spacious area network ( meshing). This types of networks are very usefull for sharing charterive information likes files, small or big document, play network games etc.Metro Politian Area Network(MAN) metropolitan area network is a large computer network where computers are connected with each other from different geographical location. Its structure and built passage are quite analogous with LAN the only difference its spans an entire city or a selected are like college or university campus or a commercial area. We can get a shared network connection form MAN.Wide Area Network (WANs)Wide area network is similar to a Local area network but here all other device connec ted to each other by fiber-optic cables, earphone line or a satellite links.Networking TopologiesBus Every customer or device are individually linked up to successive other device or other client . Its a very simple network but its has sum troubleshooting network issues . such as if a node is not working then how can anyone find the error node. Other way it has entropy redundancy issues.Ring It quite similar to bus network topologies. It has no termination like bus topologies. The main reason is that this topologes has no end it link up to each other like a circle.this network has approximately fault such as difficulty of adding a parvenue node to a token ring network.StarIn this netwrok each and every node maintains an itotally individual connection to a switch, where all other nodes are connected. It has a direct connection with swithch to node. the weakness are need more wire to frame-up a network.MeshIn this topology every node conected with each other node. It generally utilize in warreless(prenominal) network. It need a large nitty-gritty of overhead which very difficult to manage+HybridThis is simply a topology referring to the case where more than one topology is utilized. ti is the combination of leash and ring topology.1.2 Evaluate the impact of current network technology, communication and standards.AnswerOSPF It is a routing protocol generally used for larger network either a single network or a group network. It is designed by Internet Engineering Task Force. It can also used as a Gateway protocol.FTP File Transfer Protocol (FTP) is mainly a standard protocol of Network which is used to transfer data from client to troops or one server to another server . If user or admin pauperism to upload a file on a website he or she needs a username, password and host address.SMTP Simple harness transfer protocol is like a media which transfers e-mail. SMTP always work with POP3 service.TCP/IP infection Control Protocol and Internet Protocol is a set of a protocol stack. Basically it is tow different protocol. TCP/IP is closely related with FTP, SMTP, HTTP.1.3 Discuss how protocols enable the effective utilisation of different networking systems.Network Protocols are ensure proper utilisation of different network system.OSI model Layer 2 protocol is data link protocol which handles the physical and logical connections to the packets destination using a network interface card (NIC). Layer 3 Protocol called Internetwork Protocol (IP) it is also called network layer protocol it work for routing, directing datagrams from one netwrok to another. IP protocol always analysis larger datragrams and identify each and every host with a 32-bit IP address.Layer 4 protocol are TCP, UDP. Transmission Control Prtocol (Tcp0 establishes connections between two hosts on the network finished sockets which are determined by the IP address and port number. one the other side provides a low overhead transmission service, but with less error che cking.2.1 Discuss the role of software and hardware components.AnswerSoftware All Network software consists of the programs and protocols which required to connect computers together. Their primary purpose are data inter connect each other, data sharing.Application sharing For application sharing all computer use same platform to connect and manage computer. If a network share application software platform to connect then it can reduce network cost.Hardware or off-base sharingNetwork software also share hardware such as phone, fax, printer etc. A printer connected with ser with server and all other computer can share that computer.Management and SecurityNetwork software provide some mechanism to maintain proper security of data and its can make backup copy of valuable date. It can monitor and make a digital report on resource utiliaation and efficiency.Operating System Windows or Linux system.HardwareNetwork Interface card (NIC)HubSwitchesBridgesRoutersGatewayModems2.2 Discuss serv er types and selection requirement.AnswerFor the given scenario I would prefer a window server and here I want to clear my intension by full filing server selection requirement.So If any admin want to select a server types then admin must follow, server, proxy servers, web server, mail server, FTP server, SMTP server. Here I try to mention server and its work boniface A Server designed to get request or to process requests from other device or node(client) and deliver or process data to other node or client over a local network, or the wide area network.Now a days we find chaw of servers around us. So, I try to figure out some common server typesProxy Servers A proxy server like a nerve man between a client and a real server. Here client means a web browser such as Internet explorer or chrome. When a client make a inquiry then web browser its try to solve it, otherwise web browser forward the query to the real server. In this way a proxy server reduce search time.A proxy server a lso used to filter request. A network admin used it to control unauthorized web access. Such as many company block facebook, online game site etc harness Servers A mail server used for delivers e-mail over a network or over the internet. This types of servers receive e-mails from other nodes or users and send the mail to correct node or client.Web ServersWeb server generally a server which commonly used to host websites. Its deliver web varlet with content to client site and all the content are plain HTML documents or a image.Application Servers Application server generally called appserver. It is a software which controlled all application between users and an server.Real-Time Communication ServersFTP Servers File Transfer Protocol (FTP) is mainly a standard protocol of Network which is used to transfer data from client to host or one server to another server . If user or admin want to upload a file on a website he or she needs a username, password and host address.Server types sel ection is an important step for a new network. To select a server for office or a home is not easy its seems quite complicated.So an administer should make his own criteria to select server type. So, I try to set some criteria.Software requirementsCommentOperating systems (OS)WindowsCPU type and speedLattesExpansion/Upgrade CriteriaMust repel types, space, and speedsLattesPhysical characteristicsYesBrandIntel(Processor), HP (Network Printer)2.3 Discuss the inter-dependence of workstation hardware with network components.3.1 Design a networked system to meet a given specification.Answer Design of a computer network systems first think about a exchange device which could be a switch or a router, A central server, a pc for every users, hard ware components .OfficePrinterLife Insurance companyRouterAgent 6Agent 4ServerAgent 2Agent 5Life Insurance Company Network StructureAgent 3Hardware requirementNameQuantityCommentServer1Main ServerPrinter1Network PrinterRouter7Main Router, Office an d AgentsSwitch1Central switchPC9Main office and agentsSoftware requirement1.
