IntroduceIn the report, I will explain of networking principles, protocols and devices, including benefits andconstraints of networked solutions, the impact of network topology, communication and bandwidthrequirements, effectiveness of networking systems, operating principles of networking devices and servertypes and networking software.I.Examine networking principles and their protocol1.Basis of computer1.1. What is network?A network computer is a group of two and more computer connected together using atelecommunication system for the purpose of communicating and sharing resources.1.2. Benefits of network-File sharing: you can easily share data between different users or remote access if you keepit on other connected devices. (Audio, Video, Text)-Resource sharing: using networked peripherals such as printers, scanners and copiers orsharing software among multiple users, saves money. (printers, network data andapplications can be accessed by remote connection-devices, using network-connected devices).-Internet Sharing: it saves costs and can help protect your system if you properly secure thenetwork. (internet)-Increasing storage: you can access files and multimedia, such as photos and music, thatyou store remotely on other devices or attached storage devices. (NAS – Network AttachedStorage)1.3.The basic types of networkBased on geographical distanceComputer networks may be distributed in a certain area or may be within a country orglobally. Based on the scope of distribution, one can categorize the following types ofnetworks:-LAN (Local Area Network)7
Area Network (LAN) is a computer network, which is limited to small office, multiplebuilding, school by using the network media.1.1 LAN networkCons of Local Area Network: LAN has a limited range of connections. Such as office, abuilding or a school...Users have to spend the initial setup cost of installing LAN is highand if large LAN need to have an administrator to operate. LAN administrators have theright to check and access personal data and to check the computer history of each userusing the Local Area Network and LAN administrators will implement a fully functionalsecurity policy and responsible for the safety of the database So it not privacy. Alam(2014)Pros of Local Area Network (LAN): LAN helps users easily share resources, with the helpof Local Area Network. Computer hardware resources such as printers, modems, harddisks can be shared easily. LAN also help users can be save money by users can share8
