Glossary of Ethernet and Internet terms

Upstream and downstream channel transport data at different rates, i.e.
asymmetrically via a two-wire line (DLS, copper phone line) on a broadband
network.
Very little data is sent upstream, i.e. to the server, when surfing. The requested
data, however, are sent at high speed downstream to the requesting computer.
You can call or e.g. send faxes while transmitting data.
The Internet Service Provider ISP provides the ADSL connection. You need a DSL
modem for this type of connection.
see ADSL.
The bit rate describes the transmission speed or rate in bits per second (bps).
Data sent out to all participants on the network.
A client is a network device unable to execute certain services and thus requests
those services from the server. The server provides the service and sends a reply.
Gateway that is selected when one IP address is outside its own subnet and
therefore the standard gateway is unknown.
The new Dynamic Host Configuration Protocol allows for dynamic allocation of a
network configuration to clients (PC, Web Server) via a server (router).
see DSL.
The DNS allows for assigning IP addresses to names (that are easier to
remember than 32-bit IP addresses). A DNS server must manage this information
for each LAN with Internet connection. When you select an Internet page, the web
browser accesses the IP address for that site assigned by the DNS server to open
a connection.
On the Internet, domain names are assigned to IP addresses as per a hierarchical
system. A local PC only knows the address of the local DNS server. This server, in
turn, knows the addresses of all PCs on the local network as well as that of the
higher DNS servers that, in turn, know the addresses of the next higher DNS
servers.
see DNS
The domain name is the Web Server designation on the Internet. The DNS server
assigns an IP address to the domain name.
DSL is a type of data transmission allowing for 1.5 Mbps access to the Internet on
standard copper phone lines. The Internet Service Provider ISP provides the DSL
connection. You need a DSL modem for this type of connection.
