Network Physical Structures
We have said that a network is a two or more devices connected together and that a
path is set up for communication to be reached between the two. Now we will
discuss the physical connections for Networks.
There are two possible connection types when it comes to Networks
Point-to-point or Multipoint
Point-to-point connections – provides a dedicated link or between two devices.
The entire capacity of the link is reserved for transmission between those two
devices.
Most point-to-point connections use an actual length of wire or cable to connect
the two ends, but microwave or satellite links, are also possible.
Changing the T.V with a remote is a point-to-point connection between the remote
control and the television.
Multipoint connections – more than two devices are sharing a link
The entire capacity of the link is either shared spatially or temporally.
This means either every computer shares a specific space of the link or each
computer shares the link for a specific time when being used.
