What is the difference between TCP and UDP ?

Answer Posted / mukesh roy

TCP: is connection-oriented protocol. When a file or message
send it will get delivered unless connections fails. If
connection lost, the server will request the lost part.
There is no corruption while transferring a message.

UDP: is connectionless protocol. When you a send a data or
message, you don't know if it'll get there, it could get
lost on the way. There may be corruption while transferring
a message.

TCP: World Wide Web (Apache TCP port 80), e-mail (SMTP TCP
port 25 Postfix MTA), File Transfer Protocol (FTP port 21)
and Secure Shell (OpenSSH port 22) etc.

UDP: Domain Name System (DNS UDP port 53), streaming media
applications such as IPTV or movies, Voice over IP (VoIP),
Trivial File Transfer Protocol (TFTP) and online multiplayer
games etc
