During a file transfer between two systems, a brief network outage occurs. When the connection is restored, the file transfer resumes without any data loss. Which transport layer feature ensures this seamless recovery?

Connection-Oriented Communication is a feature of the transport layer, particularly in protocols like TCP. It ensures that data is reliably transmitted, and in the event of network disruptions or outages, the connection can be reestablished, and the file transfer can resume without data loss.
