- NIC - provides the hosts access to the media
- Repeater - amplifies and retimes the signal; extends the physical length of a signal; if area of LAN is more than 200 meters in diameter, one can be installed to extend network; used in an extended star topology when theatchment area of one wiring closet is not enough
- Hub - multiport repeater; center of a star topology, all segments are in the same collision domain, all segments are in the same broadcast domain
- Router - makes packet forwarding based on logical addresses (layer 3); Most important traffic-regulating device on large network; passes data packets between networks, Each segment is in a separate collision domain; each segment is a separate broadcast domain
- transceiver - converts one media type to another
- Bridge - builds a MAC address table; uses MAC for forwarding; Each segment is a separate collision domain; all segments are in the same broadcast domain
- Switch - can significantly reduce collisions - each port on its own separate bridge; uses physical address for forwarding; Each segment is a separate collision domain; all segments are in the same broadcast domain

Token Ring - logical - uses deterministic media access - ring
Bus - all of its nodes are connected directly to one physical length
Star - (disadvantage - needs a lot of network media and the network would be susceptible to problems at the central node
Extended star - LAN topology in which each of the end nodes of the core topology are acting as the center of its own star topology
Mesh - every node is linked directly to each other
FDDI - ring
