Terminology
R
Registrar
A registrar (domain name registar) is an organisation or a company that
registers Internet domains.
Remote Extension
Internal subscriber (e.g., home office, outlying parts of the building, branch
offices) connected to a central phone system via a public network (e.g., the
Internet). The distance between the phone system and the outlying
extension is not relevant.
Router
Routers connect two separate networks. This means, for example, that you
can connect the local network to another LAN or a WAN. When a PC wants
to send a data packet, this packet must travel over a router. The router uses
the IP address to detect the network it must send the data to. In addition to
connecting to networks, routers can also execute certain control functions,
such as maintaining a simple firewall. In a home network, routers are usually
used to connect the local network to the Internet and to enable simultaneous
Internet access for multiple users.
