Gateway
Gateway is a general term designating an interface be-
tween two computer networks. Such a network interface
can be realized using a router or a bridge, for instance.
If a computer wants to transfer data packets to a computer
in another network, it must first transmit the packet to the
gateway. To do this, the computer must know the address
of the gateway.
If all packets that cannot be delivered in a local network
always are to be transmitted to their given recipients via
the same gateway, for this purpose the address of the
gateway must be saved as the default gateway in the net-
work settings of the computer.
Such a default gateway for the computer is negotiated au-
tomatically by the operating system or the dialing soft-
ware whenever an ISDN-Controller or DSL-Controller estab-
lishes a connection to the Internet. If a router is used for
the shared Internet access in a local network, the IP ad-
dress of the router must be entered as the default gateway
in the TCP/IP settings of each computer that wishes to use
the Internet connection. If the TCP/IP setting is configured
by means of a DHCP server, there is no need to enter the
gateway address manually.
IP
abbreviation for Internet Protocol
The IP Internet Protocol is the most important basic proto-
col for the control of data exchange in local networks and
in the Internet. The Internet protocol works without a con-
nection; in other words, data packets are transmitted from
the sender to the recipient without previous consultation.
The addresses of the recipient and the sender in the data
packets are given as IP addresses.
