• TCP (Transmission Control Protocol) is a connection-oriented protocol. The communicating devices should create a connection before transmitting data and close the connection after transmitting the data, according to connection-orientation. TCP is dependable because it ensures data delivery to the destination router. TCP has a number of error-checking methods. It is because it allows for data flow control and acknowledgement.
• UDP stands for User Datagram Protocol. This is due to the lack of expense associated with creating, maintaining, and terminating connections. For broadcast and multicast network transmission, UDP is a good choice. In UDP, data delivery to the destination cannot be assured. UDP only provides a checksum-based error checking mechanism.
