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 protocol stack. All participants on the Internet can be iden-
tified by an IP address. Servers are addressed by Domain names (e.g. siemens.com).
Domain names are assigned to IP addresses by the Domain Name Service (DNS).
These are some of the main Internet services:
u Electronic mail (e-mail)
u The World Wide Web (WWW)
u File transfer (FTP)
u Discussion forums (Usenet / Newsgroups)
Internet service provider
An Internet service provider offers access to the Internet for a fee.
Internet telephony
Transmission of voice via the Internet (Voice over IP).
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 com-
plex network (routing).
IP address
The IP address is the unique network-wide address of a network component in a net-
work based on the TCP/IP protocols (e.g. in a local area network (LAN) or on the Inter-
net). The IP address has four parts (each with up to three-position digit sequences) sep-
arated by full stops (e.g. 10.0.0.2). The IP address comprises the network number and
the computer number. Depending on the Subnet mask, one, two or three parts form the
network number; the remainder form the computer number. You can find out the IP
address of your PC using the ipconfig command.
IP addresses can be assigned manually (see Static IP address) or automatically (see
Dynamic IP address).
On the Internet Domain names are normally used instead of the IP addresses. The DNS
is used to assign domain names to IP addresses.
The Giga762SX WLAN dsl has a Private IP address and a Public IP
address.
