Multiple Choice

FDIO messages are composed of separate sections of data called ______.

Explanation:
Messages in FDIO are organized into separate sections called fields. Each field holds a specific piece of information and has a defined position or size, which makes it possible for the receiving system to parse the message correctly. This field-based structure allows the command code, address, data payload, and status or checksum to be identified and interpreted independently, ensuring reliable communication. Blocks, segments, and records refer to different ways of grouping data in other contexts, but for FDIO messages the distinct, labeled pieces of data—fields—are the standard building blocks.
