centralized, static routing, and dynamic routing

The three fundamental approaches to routing are:

segments

The transport layer must break messages from the application layer into several _____ that can be sent to the network layer.

True

The transport layer process running on the destination computer, reassembles the fragmented application message before passing it up to the application layer

False

The transport layer routes messages through the network selecting the best path from the source to the destination station

False

There are four fundamental approaches to routing: centralized, static routing, dynamic routing, and monitor routing.

True

Translating an application layer address to a network layer address and finally to a data link layer address is called address resolution.
