TCP stands for Transmission control Protocol
UDP stands for Userdatagram Protocol.

TCP is more reliable because it always acknowledges the data.
UDP is not reliable because it doesn’t acknowledge the data.

That is the reason,

TCP is known as connection oriented and UDP is connectionless.

TCP used by web traffic like HTTP, HTTPS, SMTP.
