(addressing, protocols, application interfaces, etc.). Although it is not totally correct, the
term is also used as a synonym for router.

IEEE
Institute of Electrical and Electronics Engineers
IEEE is an international body that defines network standards, especially to standardise
LAN technologies, transmission protocols and speeds, and wiring.

IEEE 802.11
IEEE 802.11 is a standard for wireless LANs. In infrastructure mode, end devices can be
connected to a base station (access point) or 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; these are known
collectively under the name TCP/IP. All participants on the Internet can be identified by
an IP address. Servers are addressed by a domain name (e.g. gigaset.com). Domain
names are assigned to IP addresses by the Domain Name System (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)

Internet Service Provider
