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.
