DHCP Server

DHCP

DNS
Domain Name System
DNS permits the assignment of IP addresses to computers or Domain name

s

that are

easier to remember. A DNS server must administer this information for each

LAN

with

an

Internet

connection. As soon as a page on the Internet is called up, the browser

obtains the corresponding IP address from the DNS Server so that it can establish the
connection.
On the Internet, the assignment of domain names to IP addresses follows a hierarchical
system. A local PC only knows the address of the local Name Server. This in turn knows
all the addresses of the computers in the local network and the next higher Name
Server, which again knows addresses in its network and that of the next Name Server.

Domain name
The Domain name is the reference to one or more Web servers on the

Internet

. The

Domain name is mapped via the

DNS

service to the corresponding

IP address

.

DSL
Digital Subscriber Line
DSL is a data transmission technique in which a connection to the

Internet

can be run

at 1.5

Mbps

over normal telephone lines. A DSL connection is provided by an

Internet

Provider

. It requires a DSL modem.

Dynamic IP address
A dynamic

IP address

is assigned to a network component automatically via

DHCP

. This

allows the IP address of a network component to change every time it registers or in cer-
tain time intervals.

Encryption
Encryption protects confidential information against unauthorised access. With an
encryption system, data packets can be sent securely over a network. The Gigaset WLAN
Repeater 108 uses

WEP

encryption for secure data transmission over wireless networks.

Ethernet
Ethernet is a network technology for local networks (

LAN

) and has been defined by the

IEEE

as Standard IEEE 802.3. Ethernet uses a base band cable with a transmission rate

of 10 or 100

Mbps

.
