HTTP proxy
Server via which the Network subscribers can process their Internet traffic.
Hub
Uses one Infrastructure network to connect several Network subscribers. All data
sent to the hub by one network subscriber is forwarded to all network subscribers.
See also: Gateway, Router.
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 pro-
tocols, data transfer rate and wiring.
Infrastructure network
Network with central structure: All Network subscribers communicate via a central
Router.
Internet
Global WAN. A series of protocols known as TCP/IP have been defined for exchanging
data.
Every Network subscriber is 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 deter-
mines 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 pro-
tocols (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 one, two or three
parts make up the network number and the rest of the IP address addresses the net-
work 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 man-
ually (fixed IP addresses).
See also: DHCP.
IP pool range
Range of IP addresses that the DHCP server can use to assign dynamic IP addresses.
