Gateway
A Gateway is a device for connecting networks with completely different architectures
(addressing, protocols, application interfaces etc.). Although it is not totally correct, the
term is also used as a synonym for Router.
Global IP address
See Public IP address
Half duplex
Operating mode for data transfer. Only one party can receive or send data at a time.
See also: Full duplex
HTTP Proxy
An http proxy is a Server that network components use for their Internet connections.
All requests are sent via the proxy.
Hub
A hub connects several network components in a star-topology network by sending all
the data it receives from one network component to all the other network components.

IEEE
Institute of Electrical and Electronics Engineers
The IEEE is an international body for defining network standards, especially for
standardising LAN technologies, transmission protocols and speeds, and wiring.
IEEE 802.11
IEEE 802.11 is a standard for wireless 2.4-GHz band LANs. In so-called Infrastructure
mode terminals can be connected to a base station (Access Point) or they can connect
with each other spontaneously (Ad-hoc mode).
Infrastructure mode
Infrastructure mode is a way of operating wireless local networks (WLAN), in which an
Access Point handles the data traffic. Network components cannot establish a direct
connection with each other as is the case in Ad-hoc mode.
Internet
The Internet is a wide-area network (WAN), linking several million users around the
world. A number of Protocols have been created for exchanging data, and these are
known collectively as TCP/IP. All participants on the Internet are identifiable by an IP
address. Servers are addressed by a Domain name (e.g. siemens.com). Domain names
are assigned to IP addresses by the Domain Name Service (DNS).
Among the most important Internet services are:
u
electronic mail (email)
u
the World Wide Web (WWW)
u
file transfer (FTP)
u
discussion forums (Usenet / Newsgroups)
