Glossary
FTP
File Transfer Protocol. Protocol for exchanging files via the Internet. FTP is used, for
example, to make files available for download or to receive files from other users.
Full duplex
Data transmission operating mode in which data can be sent and received at the same
time.
FXS
Foreign Exchange Station. Phone port to which an analogue terminal (phone, fax or
answer machine) can be connected.
Gateway
A gateway connects networks with one another. In contrast to a Router, a gateway is
not dependent on protocol, i.e. it is also able to establish connections between net-
works with a different architecture (protocols, application interfaces etc.).
Half duplex
Operating mode for data transfer. Only one party can receive or send data at a time.
HTTP
Hypertext Transfer Protocol. Network protocol for the transmission of data, which is
mainly used for transmitting and displaying Internet content.
HTTP proxy
An HTTP proxy is a server that network components use for their Internet traffic. All
requests are sent via the proxy.
Hub
A hub is a central distribution point in a network, to which PCs and other network
devices are connected. The hub forwards received data to all connected PCs. For this
reason, in large networks, a Switch is recommended to ensure that data is only sent to
the PC requesting it.
IEEE
Institute of Electrical and Electronics Engineers. The IEEE is an international body for
defining network standards, especially for standardising LAN technologies, transmis-
sion protocols and speeds, and wiring.
