Q: What is the biggest difference between TCP and UDP?
or
Q: What distinguishes TCP from UDP the most?
- TCP requires less overhead for DNS.
- More traffic can be transmitted using UDP.
- TCP is connectionless.
- UDP is connectionless
Explanation: The most significant distinction between Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) is that TCP is connection-oriented, which means that it establishes a connection before the transfer of data and guarantees reliable delivery through features such as sequencing and acknowledgments. On the other hand, UDP is connectionless, which means that it does not establish a connection before the transmission of data and does not guarantee delivery or sequencing.
