Final answer:
Data fragmentation is the term for a chunk of data sent over a network, where larger messages are divided into packets that may arrive at the destination in order, out-of-order, or not at all.
Step-by-step explanation:
The term for a chunk of data sent over a network, where larger messages are divided into packets that may arrive at the destination in order, out-of-order, or not at all is Data fragmentation. Data fragmentation is a process where data is broken down into smaller packets for efficient transmission over a network. These packets can be transmitted independently and can arrive at the destination in a non-sequential order. This fragmentation technique helps improve the reliability and efficiency of data transmission over a network.
