This describes the most important terms and abbreviations of this manual.
AT command: Commands to devices such as modems to set up this device.
CHAP: Challenge Handshake Authentication Protocol; authentication protocol
often used for -> PPP connections.
DHCP: Dynamic Host Configuration Protocol; DHCP servers can dynamically design
an IP address and other parameters to DHCP clients, on request.
Dial-In: MoRoS can be called via a Dial-In connection and then create a connection
to the LAN.
Dial-Out: MoRoS can use a Dial-up to make calls and to perform Internet
connections, for example.
Gateway: This is a machine that works like a -> Router. In contrast to the router, a
gateway can also route data packets from different hardware networks.
ISP: Internet Service Provider; an ISP can be called using a dial-up connection
(e.g. with an analogue modem or ISDN-TA). The ISP will then provide access
to the Internet via this dial-up connection.
LAN: Local Area Network; a network of computers which are located relatively
close to each other.
MAC address: Media Access Control Address. A MAC is a part of an Ethernet
interface. Each Ethernet interface has a unique global number, the MAC
address.
PAP: Password Authentication Protocol; an authentication protocol often used
for -> PPP connections.
PPP: Point to Point Protocol; a protocol, which connects two machines via a
serial line to enable the exchange of TCP/IP packets between those two
machines.
Router: This is a machine in a network, which is responsible for the incoming data
of a protocol to be forwarded to the planned destination or sub network.
Switch: A device that can connect several machines with the Ethernet. In contrast
to a hub, a switch will "think” by itself, i.e. it can remember the MAC
addresses connected to a port and directs the traffic more efficiently to the
individual ports.
URL: “Uniform Resource Locator”; this is the address used by a service to be
found in the web browser. In this manual, an URL is mostly entered as the
IP address of the MoRoS.
WAN: Wide Area Network; a network consisting of computers, which are located
far away from each other.
