Question

Suppose you wanted to do a transaction from a remote client to a server as fast as possible. Would you use udp or tcp? Why?

Answer 1

Explanation:

Since TCP guarantees packet delivery and thus can be considered "reliable", whereas UDP doesn't guarantee anything and packets can be lost. What would be the advantage of transmitting data using UDP in an application rather than over a TCP stream? In what kind of situations would UDP be the better choice, and why?

I'm assuming that UDP is faster since it doesn't have the overhead of creating and maintaining a stream, but wouldn't that be irrelevant if some data never reaches its destination?

Answer 2

Answer:

UDP will be selected if compared to TCP as it is faster

Explanation:

the UDP is  depending on nonexistent acknowledge packet (ACK) that permits a continuous packet stream, instead of TCP that acknowledges a set of packets, calculated by using the TCP window size and round-trip time (RTT).
