z
TCP ( Transmission Control Protocol) - A method (protocol)
used along with the Internet Protocol (Internet Protocol) to
send data in the form of message units between
computers over the Internet. While IP takes care of
handling the actual delivery of the data, TCP takes care of
keeping track of the individual units of data (called packets)
that a message is divided into for efficient routing through
the Internet.
z
UDP ( User Datagram Protocol) - A communications
method (protocol) that offers a limited amount of service
when messages are exchanged between computers in a
network that uses the Internet Protocol (IP). UDP is an
alternative to the TCP and, together with IP, is sometimes
referred to as UDP/IP. Like the Transmission Control
Protocol, UDP uses the Internet Protocol to actually get a
data unit (called a datagram) from one computer to
another. Unlike TCP, however, UDP does not provide the
service of dividing a message into packets (datagram’s)
and reassembling it at the other end. Specifically, UDP
doesn't provide sequencing of the packets that the data
arrives in. This means that the application program that
uses UDP must be able to make sure that the entire
message has arrived and is in the right order. Network
applications that want to save processing time because
they have very small data units to exchange (and
therefore very little message reassembling to do) may
prefer UDP to TCP.
