What is defined as user-submitted data during system connection?

User-submitted data during a system connection is best characterized as Registered Data. This term specifically refers to the information entered or provided by users when they establish a connection to the system. It can include details such as user credentials, device identifiers, or any other relevant information that ensures the system can identify and authenticate the user or the device connecting to it.

This classification is essential as it differentiates this data from other types such as System Data, which often encompasses pre-configured or default settings of the system; Real-time Data, which includes information generated and displayed instantly during operation; and Historical Data, that refers to records of past data or past operational metrics. Recognizing Registered Data as distinct helps in managing and processing user inputs efficiently within the system's framework.
