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 .
