I only know about UDP is unreliable and connectionless
protocol.And TCP/IP protocol is connection oriented and
reliable.i want some more advantages and disadvantages and
UDP where its used.
UDP: It doesn't wait for acknowledgement as like TCP/IP so
it is unreliable protocol.
UDP is usually used in where communication needs to be fast
like in DNS and DHCP.
The first thing is UDP is connection less where as TCP is
connection oriented.The broadcasting and multicasting
software is available in the UDP only.Why because it is
connection less hence we can broadcast the packets very
easily,no need to wait for connection like in tcp,which
takes more delay.
