fixed IP address
Fixed IP addresses are IP addresses which are
permanently assigned to a computer or another device
like a network printer.
Assigning fixed IP addresses makes sense in cases where
a local network has a sufficiently large pool of IP
addresses available, or when a computer is always
supposed to be accessible at a certain address (such as a
web server or e-mail server).
FTP
abbreviation for File Transfer Protocol
The File Transfer Protocol allows files to be exchanged
between two computers operating in the Internet. Data
exchange takes place via an FTP server and what is known
as an FTP client. The more convenient FTP clients are
available as stand-alone software or are components of
some ISDN data transfer software; simple FTP clients are
now included in many web browsers.
gateway
Gateway is a general term designating an interface
between two computer networks. Such a network
interface can be realized using a router or a bridge, for
instance.
If a PC wants to transfer data packets to a PC in another
network, it must first transmit the packet to the gateway.
To do this, the PC 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
network settings of the PC.
Such a default gateway for the PC is negotiated
automatically by the operating system or the dialing
software whenever an ISDN-Controller or DSL-Controller
establishes a connection to the Internet. If a router is used
for the shared Internet access in a local network, the IP
address of the router must be entered as the default
gateway in the TCP/IP settings of each PC that wishes to
