This
devices act as an interface between the sending and receiving devices
and the communication channel. They convert outgoing messages into
packets that can travel across the communication channel. Each packet
contains the data, as well as the recipient, the sender, and the
sequence information used to reassemble (used protocol ) the data at
the destination. - Protocol is a set of rules that govern data communication.
