Show answer & explanation
Correct answer: D
Concept
Packet-switched communication divides application data into manageable transmission units before sending it.
Each unit carries a payload and control information so intermediary devices can forward it and the receiver can reassemble the data.
Application
An e-mail message is application data. During transmission over a packet-switched network, the message is divided into packets.
Contrast
Bytes are groups of eight bits used to represent digital data; they are not the delivery units named by the question.
Digits are symbols used to write numbers; in binary notation, those symbols are 0 and 1.
A process is a running instance of a program managed by an operating system.
Packets are formatted units that carry payload and delivery-control information across a network.
Result
Therefore, the message pieces are called packets.
