takes care of handling the actual delivery of the data, TCP takes
care of keeping track of the packets that a message is divided into
for efficient routing through the Internet. For example, when a web
page is downloaded from a web server, the TCP program layer in
that server divides the file into packets, numbers the packets, and
then forwards them individually to the IP program layer. Although
each packet has the same destination IP address, it may get routed
differently through the network. At the other end, TCP reassembles
the individual packets and waits until they have all arrived to
forward them as a single file.
TCP/IP (Transmission Control Protocol/Internet Protocol).The
underlying technology behind the Internet and communications
between computers in a network. The first part, TCP, is the
transport part, which matches the size of the messages on either
end and guarantees that the correct message has been received.
The IP part is the user’s computer address on a network. Every
computer in a TCP/IP network has its own IP address that is either
dynamically assigned at startup or permanently assigned. All TCP/
IP messages contain the address of the destination network as well
as the address of the destination station. This enables TCP/IP
messages to be transmitted to multiple networks (subnets) within
an organization or worldwide.
UPnP. A networking architecture that provides compatibility among
networking equipment, software and peripherals of the 400+
vendors that are part of the Universal Plug and Play Forum. UPnP
