TCP/IP
abbreviation for Transmission Control Protocol / Internet
Protocol
TCP/IP is the “language” of the Internet. TCP/IP is used to
refer to a suite of protocols used for data communication
over the Internet. TCP and IP are the network and transport
protocols underlying most Internet services, including file
transfer (FTP) and e-mail communication (SMTP). TCP/IP is
available for practically all computer systems. TCP/IP thus
offers the advantage of trouble-free communication be-
tween otherwise incompatible networks and systems.
Update
A more recent version of software or firmware is called an
update. Updates are often free of charge, resolve minor
programming errors, and sometimes also offer new func-
tions.
Upload
This term designates the procedure of transmitting files
from one’s own computer to another computer in the Inter-
net.
UPnP
abbreviation for Universal Plug and Play (UPnP)
UPnP is an extension of the Microsoft Plug & Play standard
that allows devices to network globally and to exchange
services—without a central server or computer.
UPnP allows devices from all kinds of manufacturers (ste-
reo systems, routers, printers, house controls) to be con-
trolled via an IP-based network, with or without central
control through a gateway. It is based on a number of
standardized network protocols and data formats. Ex-
pressed simplistically, devices can communicate with
each other using UPnP to exchange information.
Today the UPnP forum specifies the UPnP standard and
certifies devices that are compliant with the standard.
