Description
UDP versus TCP
. (User Datagram Protocol versus Transmission Control
Protocol). UDP provides unguaranteed, connectionless transmission of data across
an IP network. By contrast, TCP provides reliable, connection-oriented transmission
of data.Both TCP and UDP split data into packets called "datagrams." However,
TCP includes extra headers in the datagram to enable retransmission of lost packets
and reassembly of packets into their correct order if they arrive out of order. UDP
does not provide this. Lost UDP packets are unretrievable; that is, out-of-order
UDP packets cannot be reconstituted in their proper order..
Despite these obvious disadvantages, UDP packets can be transmitted much faster
than TCP packets -- as much as three times faster. In certain applications, like audio
and video data transmission, the need for high speed outweighs the need for
verified data integrity. Sound or pictures often remain intelligible despite a certain
amount of lost or disordered data packets (which appear as static).
IP address of the TalkAnytime. For an IP address to be displayed here, the
TalkAnytime must have DHCP enabled. Its IP address, in such a case, is assigned
by the DHCP server.
