Three types of topology design according to OSI model
Layer 1 - Physical LayerRelated to type of transmission lines such as CAT5 UTP andfiber-opticcable and also EIA/TIA 568 standard for line connection
Layer 2 - Data Link LayerRelated to selection of layer-2 devices, e.g. bridges or LAN switchesfor connecting layer-1 devices to LAN segment. Layer-2 layer devices define collision and broadcast domains.
Layer 3 - Network LayerRelated to selection of layer-3 devices, e.g. routers that create unique LAN segments and communicate using layer 3 address such IP address
Divide network into small segments to improve overall bandwidth of network
Installation of LAN switching atMDF and IDFs affects size of collision domains and data speed in each of horizontal cable and vertical cable. Vertical cable must handle all data traffic between MDF and IDFs therefore requires higher capacity
