While making applications App developer assign port numbers according to the importance of application, they can choose TCP or UDP at the transport layer... Some applications may tolerate packet loss so they are on UDP ports...

UDP protocol works with no acknowledgement but is fast compared to TCP so for many purpose UDP is used where acknowledgement is not required like DNS

For the faster transfer data, instead of TCP, UDP protocol is use. But TCP is a reliable protocol where as UDP is non reliable protocol.
TCP process are
segmenting
sequencing
windowing (error checking)
reassembling

UDP Process are
segmenting
sequencing
reassembling

Without error checking UDP send the data to the destination point. And even not give any information to the sender whether the data is received by receiver or no.
so its perform first than TCP .

Transport Layer is Forth Laye in the OSI modal ,It perform transmission of data
In transport layer,there must Be two ways of communication,
CONNECTION ORIENTED & CONNECTION LESS

IN CONNECTION ORIENTED is used for Long Distance,it is secure communication,uses Protocol Such as TCP/IP.
AND
IN CONNECTION LESS , is used for SHORT Distanced Not secured,used UDP PROTOCOL
