cations separate on the network?

17.
Which layer segments and reassembles data into a data stream?
18.
Which layer provides the physical transmission of the data and han-
dles error notification, network topology, and flow control?
19.
Which manages device addressing, tracks the location of device on the
network, and determines the best way to move data?
