The advantages and disadvantages of Client Server Networks and Wireless networks Client Server Networks Advantages: • Security is better – because it is centralised and a person is given responsibility for it • Centralised data – data is all held on the file server which means that all users have access to the same set if data • Backups are taken centrally – regular backups are taken by the network manager which means data and programs are unlikely to be lost • Faster access to programs and files – servers are used which are powerful computers, so the whole network runs faster • Centralised administration – all the administration of the network (e.g., allocation of usernames and passwords, help, etc.) is performed centrally so users do not have to worry about it. Disadvantages: • More expensive – servers are expensive • Need specialist knowledge – need to have a person who understands the technicalities of a network in change of the network • Software is sophisticated and expensive – network operating systems are expensive. For larger client-server networks it may be necessary to buy network management software • If the server breaks down it renders the network unusable until it can be repaired. Wireless networking Advantages of wireless networks: • Allows expensive LANS to be set up without cables • Allows people the freedom of working anywhere a signal can be received • Ideal for networks in old listed buildings where cables would not be allowed to be installed • Global set of standards – you can use Wi-Fi all over the world. Disadvantages of wireless networks: • Power consumption is high – which means laptops soon exhaust their rechargeable batteries • There may be health problems in using Wi-Fi • There may be security problems even when encryption is used • Home networks have a very limited range (e.g., 150ft) • Can get interference
