allows communication and collaboration between users the uses of a network simultaneous access to data data files are shared access can be limited shared files stored on a server software can be shared site licenses network versions application servers teaching tip figure ۹a.۲ on page ۳۴۲ visually describes the sharing process. it can be helpful to have students open a shared file that you control. make a change then have the students open it again. alternatively share a document and allow your students to write in it. then demonstrate how the shared document changes. spend time discussing why application servers need to be so powerful. the uses of a network shared peripheral device printers and faxes are common shares reduces the cost per user devices can be connected to the network print servers control network printing manage the print queue teaching tip figure ۹a.۴ on page ۳۴۴ shows a print queue. it can be helpful to demonstrate your classroom queue. sharing data file server contains documents used by other computers. the uses of a network personal communication email instantaneous communication conferencing tele conferencing videoconferencing audio conferencing data conferencing voice over ip phone communication over network wires teaching tip it is fun if you can setup a teleconference in your classroom. students get to learn how to join or create the conference. additionally they learn how to participate. finally students have fun especially with shared whiteboards. voice over ip the uses of a network easier data backup backup copies data to

and xp is capable of performing this chore. common network types local area network lan contains printers servers and computers systems are close to each other contained in one office or building organizations often have several lans teaching tip use a real world example to describe an organization with interconnected lans. common network types wide area networks wan two or more lans connected over a large geographic area typically use public or leased lines phone lines satellite the internet is a wan teaching tip blockbuster video uses a wan to connect it’s stores nationwide. customers from pittsburgh may rent videos in hilton head. late fees will even be displayed hybrid network types campus area networks can a lan in one large geographic area resources related to the same organization each department shares the lan hybrid network types metropolitan area network man large network that connects different organizations shares regional resources a network provider sells time teaching tip an example of a regional resource is a supercomputer. for example pittsburgh has the pittsburgh super computing center . the various colleges in pittsburgh connect to the center through a man in pittsburgh. hybrid network types home area network han small scale network connects computers and entertainment appliances found mainly in the home hybrid network types personal area network pan very small scale network range is less than ۲ meters cell phones pdas mp۳ players insider information pan is very new. few devices support pan. high end cell phones include bluetooth technology. once the technology matures bluetooth will allow the creation of a pan. how networks are structured server based network node is any network device servers control what the node accesses users gain access by logging in server is the most important computer teaching tip spend a few minutes here discussing password policies. describe why it is important not to give out a password. also describe why longer more complicated passwords are important. how networks are structured client server network nodes and servers share data roles nodes are called clients servers are used to control access database software access to data controlled by server server is the most important computer how networks are structured peer to peer networks p۲pn all nodes are equal nodes access resources on other nodes each node controls its own resources most modern os allow p۲pn distributing computing is a form kazaa teaching tip discuss how users managing their own security settings can be bad. network topologies topology logical layout of wires and equipment choice affects network performance network size network collision detection several different types teaching tip discuss how your network topology handles collisions. if your students are technical contrast this with an inferior topology. network topologies packets pieces of data transmitted over a network packets are created by sending node data is reassembled by receiving node packet header sending and receiving address packet payload number and size of data actual data packet error control teaching tip for technical students take the time to draw the packet structure on the board. the typical structure is destination address sending address packet number total packets data size payload error control. network topologies bus topology also called linear bus one wire connects all nodes terminator ends the wires advantages easy to setup small amount of wire disadvantages slow easy to crash teaching tip pages ۳۵۲ and ۳۵۳ have diagrams of each network topology network topologies star topology all nodes connect to a hub packets sent to hub hub sends packet to destination advantages easy to setup one cable can not crash network disadvantages one hub crashing downs entire network uses lots of cable most common topology star topology network topologies ring topology nodes connected in a circle tokens used to transmit data nodes must wait for token to send advantages time to send data is known no data collisions disadvantages slow lots of cable network topologies mesh topology all computers connected together internet is a mesh network advantage data will always be delivered disadvantages lots of cable hard to setup mesh topology network media links that connect nodes choice impacts speed security size wire based media twisted pair cabling most common lan cable called cat۵ or ۱ baset four pairs of copper cable twisted may be shielded from interference speeds range from ۱ mbps to ۱ mbps insider information interference is usually electrical. magnets solar flares or electronic devices generate interference. wire based media coaxial cable similar to cable tv wire one wire runs through cable shielded from interference speeds up to ۱ mbps nearly obsolete wire based …
