In UDP, as you have read above, every time you send a
datagram, you have to send the local descriptor and the
socket address of the receiving socket along with it. Since
TCP is a connection-oriented protocol, on the other hand, a
connection must be established before communications
between the pair of sockets start. So there is a connection
setup time in TCP. UDP is an unreliable protocol -- there
is no guarantee that the datagrams you have sent will be
received in the same order by the receiving socket. On the
other hand, TCP is a reliable protocol; it is guaranteed
that the packets you send will be received in the order in
which they were sent.
In short, TCP is useful for implementing network services --
such as remote login (rlogin, telnet) and file transfer
(FTP) -- which require data of indefinite length to be
transferred. UDP is less complex and incurs fewer
overheads. It is often used in implementing client/server
applications in distributed systems built over local area
networks.
