3. The data exchanged between two nodes
of a network during a telematic
communication follow precise rules
dictated by network protocols, whose job
is to regulate the flow of data between
the router and the router and determine
which path should follow the data
packets in transit.
4. The routing protocol there is the set of
rules that specifies how two routers
communicate with each other.
These protocols provide all the
information necessary to select the fastest
way to pass the packets.
Thanks to the routing protocols a single
router can receive information about the
external nodes to their small group.
What are the routing protocols?
5. In general, a tier is a row or layer in a
series of similarly arranged objects.
In computer programming, the parts of a
program can be distributed among
several tiers, each located in a different
computer in a network. Such a program is
said to be tiered.
