Roaming
Roaming extends the range of a wireless LAN by using several
Access points
that use the
same
SSID
and the same radio channel and are linked via
Ethernet
. The PCs in the net-
work can switch dynamically between several access points without losing the existing
network connection.
Router
A router directs data packets from one local network (
LAN
) to another via the fastest
route. A router makes it possible to connect networks that have different network tech-
nologies. For example, it can link a local network with
Ethernet
or
WLAN
technology to
the
Internet
.

Server
A server makes a service available to other network components (
Clients
). The term
"server" is often used to refer to a computer or PC. However, it can also mean an appli-
cation that provides a particular service such as
DNS
, Web server, file server or print
server.
SMTP
Simple Mail Transfer Protocol
The SMTP
Protocol
is part of the
TCP/IP
protocol family. It governs the exchange of elec-
tronic mail on the
Internet
. Your
Internet service provider
provides you with access to an
SMTP server.
SNMP
Simple Network Management Protocol
The SNMP
Protocol
is part of the
TCP/IP
protocol family. It provides a simple procedure
for administering the network based on a system of shared information for manage-
ment data and network management messages (known as traps) and reports the occur-
rence of events within the monitored network (e.g. an alarm message or notification of
configuration changes).
SSID
Service Set Identifier
The SSID is used to identify the stations in a wireless network (
WLAN
). All wireless net-
work components with the same SSID form a common network. The SSID can be
assigned by the network operator.
Static IP address
A static
IP address
is assigned to a network component manually during network con-
figuration. Unlike the
Dynamic IP address
, a static (fixed) IP address never changes.
Subnet
A subnet divides a network into smaller units.
