Final answer:
Terminal Node is typically the last connection to a base data network where mission operations are executed. It represents a final endpoint for data transmission in network topologies.
Step-by-step explanation:
The term you're likely asking about is Terminal Node. This is the node that is usually the last connection to the base data network. In the context of network topology and communications, a terminal node functions as a final endpoint for data transmission, and is where operational tasks, such as mission operations, are carried out. In a more general sense, this concept is applicable to various networks, including satellite communications, military networks, and other infrastructure requiring a clearly defined end-point for data flow where vital operations are managed.
