“Line Configuration refers to the way two or more devices attach to a Link”
A link is the physical communication path that transfers data from one device to the other. Link can be thought of as a Line drawn between two points. For communication to occur, two devices must be connected to each other using a link.
™ Point-to-Point Line Configuration
Dedicated Link between two devices. Entire Capacity of the channel is reserved for TX B/w these two devices. Mostly point-to-point connection use wire/cable to connect with each other. But Microwave, Satellite Links can also be used Data and Control information pas directly between entities with no intervening agent
™ Multipoint Line Configuration
More than two devices share the Link that is the capacity of the channel is SHARED now. With shared capacity, there can be two possibilities in a Multipoint Line Config:
Spatial Sharing: If several devices can share the link simultaneously, its called Spatially shared line configuration
Temporal (Time) Sharing: If users must take turns using the link , then its called Temporally shared or Time Shared Line Configuration
