Internet

connections.

All requests are sent via the proxy.

IEEE
Institute of Electrical and Electronic 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 LAN's in the 2.4 GHz band. 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 parties on the Internet can be identified 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:

electronic mail (email)

the World Wide Web (WWW)

file transfer (FTP)

discussion forums (Usenet / Newsgroups)

Internet Service Provider
An Internet Service Provider offers access to the

Internet

for a fee.

IP
Internet Protocol
The IP

Protocol

is one of the

TCP/IP

protocols. It is responsible for addressing parties in a

network using

IP addresses

, and routes data from the sender to the recipient. It decides

the paths along which the data packets travel from the sender to the recipient in a

complex network (routing).
