Question

Connection oriented protocol vs Connectionless protocol 

Answer 1

Feature	Connection-Oriented Protocol	Connectionless Protocol
Establishment of Connection	A dedicated connection is established before data transfer.	No dedicated connection is established; each packet is treated independently.
Reliability	High reliability, as it ensures data integrity and order.	Generally less reliable, as there is no guarantee of packet delivery or order.
Acknowledgment	Acknowledgments are used to confirm successful data packet delivery.	No acknowledgments are provided, and lost packets may not be retransmitted.
Sequential Data Transfer	Data is sent and received in a sequential manner, maintaining order.	Each packet is sent independently, and the order of arrival may vary.
Overhead	More overhead due to the establishment and maintenance of connections.	Less overhead, as there is no need to set up and tear down connections.
Example Protocol	TCP (Transmission Control Protocol)	UDP (User Datagram Protocol)
