  2. Introduction Whatisa LAN? Whatistopology?

  3. TopologyTypes • 1.  Bus • 2. Star • 3. Point To Point • 4. Point to Multipoint • 5. Ring

  4. BUS TOPOLOGY • single wire (coaxial), • physicalmediaisshared • onlyonecantransmit • alldeviceshearall communication • collisioncanoccur • moderninstallations usestar

  5. STAR TOPOLOGY • themost commonnetworktopology • devicesconnected to a centralconnectionpoint • hub repalcedswitch

  6. RING TOPOLOGY • usingpairedphysicalinterfaces • transmit in onedirectiononly • similarto bus • occasionallyused • highsecurity • hard to overhead

  7. POINT TO POINT • oftenconnectionbetweentwodevices • end-to-endcommunicationspath. • onlytwodevices on theconnection

  8. POINT TO MULTIPOINT • usuallyused in Wifinetworks • are used in school • connectsmultiplenetworklocationstogether

  9. CONCLUSION Most usedtopologies: BUS, STAR BusBenefits:Disavantages • cheaphistorical • easy to make StarBenefits:Disavantages • fastcostly • universal
