Differentiate UDP and TDP.

UDP
· UDP is a standard protocol with STD number 6.
· UDP is described by RFC 768 – User Datagram Protocol.
· Its status is standard and almost every TCP/IP implementation intended for small data units transfer or those which can afford to lose a little amount of data (such as multimedia streaming) will include UDP.
· UDP is basically an application interface to IP. It adds no reliability, flow-control, or error recovery to IP.
· It simply serves as a multiplexer/de-multiplexer for sending and receiving datagrams, using ports to direct the datagrams,
· unlike UDP, which is connectionless.

TCP
· TCP is a standard protocol with STD number 7.
· TCP is described by RFC 793 – Transmission Control Protocol.
· Its status is standard, and in practice, every TCP/IP implementation that is not used exclusively for routing will include TCP.
· TCP provides considerably more facilities for applications than UDP. Specifically, this includes error recovery, flow control, and reliability.
· TCP is a connection-oriented protocol, Most of the user application protocols, such as Telnet and FTP, use TCP.
· The two processes communicate with each other over a TCP connection (Inter-Process Communication, or IPC).
