Hubs

twisted pair. hub. Hubs. Hubs are essentially physical-layer repeaters: bits coming from one link go out all other links at the same rate no frame buffering no CSMA/CD at hub: adapters detect collisions provides net management functionality. Manchester encoding. Used in 10BaseT

Point to Point Data Link Control

Point to Point Data Link Control. one sender, one receiver, one link: easier than broadcast link: no Media Access Control no need for explicit MAC addressing e.g., dialup link, ISDN line popular point-to-point DLC protocols: PPP (point-to-point protocol)
