Question

Accepted Answer

UDP is a connectionless protocol that provides no guarantee of delivery, while TCP is a connection-oriented protocol that ensures reliable delivery.

UDP is faster and more efficient for streaming data, while TCP is better for applications that require reliable data transmission.
UDP does not establish a connection before sending data, while TCP does.
UDP does not provide error checking or correction, while TCP does.
Examples of UDP applications include video streaming and online gaming, while examples of TCP applications include email and file transfer.
UDP uses a simple header with fewer fields, while TCP uses a more complex header with additional fields for sequencing and acknowledgement.
UDP is used for real-time applications where speed is more important than accuracy, while TCP is used for applications where accuracy is more important than speed.
