TCP
Connection oriented protocol
Acknowledged one
Reliable
Point to point communication
slow
More traffic
Ex:- Telepbonic communication,
UDP
Connection less protocol
No Acknowledged
UnReliable
Point to Multiple point communication
Fast
less traffic
Ex:- Post letter communication,

Answer / rajarr
TCP is a connection oriented protocol, which means that
everytime a packet is sent say from host A to B, we will get
an acknowledgement.
UDP on the other hand, is a connection less protocol.
TCP -> Say you have a file transfer and you need to ensure
that the file reaches intact, and time is not a factor, in
such a case we can use TCP.
UDP-> Media Streaming, question is say you are watching a
movie?would you prefer that your movie comes..perfectly?.but
u need to wait a long time before you see the next frame
?..or would you prefer the movie to keep streaming?Yes?The
second option is definely better?.This is when we need UDP

TCP : Transmission control protocol
It is reliable connection
(reliable means sure)
It has acknowledgment
( when the packet is sent. it will get confirmation that
packet has sent successfully to destination )
Tcp port no is 7
TCP has low communication
TCP services are secure and reliable
TCP has heavy traffic
example for TCP are : Http,Ftp,Tftp,etc...
It controls the error correction
UDP: Userdatagram protcol
UDP is a non reliable connection
no acknowledgment reqired
UDP port no is 17
UDP does not contains error correction
UDP is non- reliable
UDP has High communication
UDP has less traffic
Examples of UDP are dns, dhcp,etc....

Answer / s.srikanth
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.
