Glossary
I
IEEE
Institute of Electrical and Electronics Engineers
International body that defines standards in electronics and electrical engineering,
concerned in particular with the standardisation of LAN technology, transmission protocols,
data transfer rate and wiring.
Infrastructure network
Network with a central structure: All Network subscribers communicate using a central
Router .
Internet
Global WAN . A series of protocols known as TCP/IP have been defined for exchanging data.
Network subscribers are identifiable via their IP address . DNS assigns an IP address to
Domain Names .
Important services on the Internet include the World Wide Web (WWW), e-mail, file transfer
and discussion forums.
Internet Service Provider
Enables access to the Internet for a fee.
IP (Internet Protocol)
TCP/IP protocol on the Internet . It is responsible for the addressing of subscribers in a
Network using IP addresses and routes data from the sender to the recipient. IP determines
the paths (routing) along which the data packets travel.
IP address
A unique address for a network component within a network based on the TCP/IP protocols
(e.g. LAN, Internet). On the
Internet , domain names are usually assigned instead of IP
addresses. DNS assigns the corresponding IP address to the domain name.
The IP address has four parts (decimal numbers between 0 and 255) separated by full stops
(e.g. 230.94.233.2).
The IP address is made up of the network number and the number of the Network
subscriber (e.g. phone). Depending on the Subnet mask, the first, second or third part makes
up the network number and the rest of the IP address addresses the network component.
The network number of all the components in any one network must be identical.
IP addresses can be assigned automatically with DHCP (dynamic IP addresses) or manually
(fixed IP addresses).
See also: DHCP .
IP pool range
Range of IP addresses that the DHCP server can use to assign dynamic IP addresses.
L
LAN
Local Area Network
Network with a restricted physical range. A LAN can be wireless (WLAN) and/or wired.
Local IP address
The local or private IP address is the address for a network component in the local network
(LAN). The network operator can assign any address they want. Devices that act as a link from
a local network to the Internet (gateway or router) have a public and a private IP address.
