Question: 1 / 1980

What is Normal Response Mode (NRM) associated with?

A method for unencrypted data transmission

SDLC/HDLC protocols allowing controlled node communication

Normal Response Mode (NRM) is primarily associated with SDLC (Synchronous Data Link Control) and HDLC (High-Level Data Link Control) protocols. In this context, NRM is a mode of communication that allows for controlled communication between nodes in a network, where the primary node (the master) can send commands and the secondary nodes respond. This structured approach helps to manage data transmission effectively, ensuring that the master node dictates the communication flow, which is essential for maintaining organized and reliable data exchange between devices.

This mode is particularly useful in scenarios where multiple nodes need to communicate without causing data collisions, as it helps regulate when each device can transmit and when it must wait for permission to respond. The designed nature of these protocols helps in establishing a reliable link and ensures that data integrity is maintained during transmission.
