(25 cards)
Which protocol characteristic defines the specific structure or format a message must have when sent?
Message format
Which process adds a header containing source and destination addressing information to data packets for correct delivery across the network?
Encapsulation
Which process converts messages into bits encoded as sounds, light waves, or electrical impulses depending on the network media?
