DHCP ServerSee DHCPDNSDomain Name System

DNS permits the assignment of IP addresses to computers or Domain names 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.

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.

DSLDigital 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 certain time intervals.

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.
