I
IEEE
Institute of Electrical and Electronics Engineers
International body that defines standards in electronics and electro-technology, con-
cerned in particular with the standardisation of LAN technology, transmission protocols,
data transfer rate and wiring.
Infrastructure network
Network with central structure: all Network subscribers communicate via a central
Router.
Instant messaging
Service that uses a client program to allow chatting in real time, i.e. to send brief mes-
sages to other subscribers on the Internet.
Internet
Global WAN. A series of protocols have been defined for exchanging data, known by the
name TCP/IP.
All Network subscribers are identifiable via their IP address. DNS assigns a Domain
name to the IP address.
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. IP is responsible for addressing subscribers in a Net-
work 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 proto-
cols (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 sub-
scribers (e.g. phone). Depending on the Subnet mask, the front one, two or three parts
make up the network number and the rest of the IP address addresses the network com-
ponent. The network number of all the components in any one network must be iden-
tical.
IP addresses can be assigned automatically with DHCP (dynamic IP addresses) or manu-
ally (static IP addresses).
See also: DHCP.
IP pool range
Range of IP addresses that the DHCP server can use to assign dynamic IP addresses.
