MAC address
Media Access Control
The MAC address is used for the globally unique identification of a
Network
adapters. It
comprises six parts (hexadecimal numbers), e.g. 00-90-96-34-00-1A. The MAC address
is assigned by the network adapter manufacturer and should not be changed.
Mbps
Million bits per second
Specification of the transfer speed in a network.
MER
MAC Encapsulated Routing
MRU
Maximum Receive Unit
The MRU defines the maximum user data volume within a data packet.
MTU
Maximum Transmission Unit
The MTU defines the maximum length of a data packet that can be carried over the net-
work at any one time.
NAT
Network Address Translation
NAT is a method for converting IP addresses
(Private IP
addresses) within a network into
one or several
Public IP addresses
on the Internet. With NAT, several network compo-
nents in a
LAN
can share the router's public IP address to connect to the Internet. The
network components of the local network are hidden behind the router's IP address reg-
istered on the Internet. Because of this security function, NAT is frequently used as part
of the
Firewall
of a network. If you want to make services on a PC in the local network
available on the Internet despite NAT, you can configure the Gigaset SX763 WLAN dsl as
a
Virtual
server.
Network
A network is a group of devices connected in wired or wireless mode so that they can
share resources such as data and peripherals. A general distinction is made between
local networks (LANs) and wide-area networks (WANs).
Network adapter
The network adapter is the hardware device that creates the connection between a net-
work component and a local network. The connection can be wired or wireless. An Eth-
ernet network card is an example of a wired network adapter. The Gigaset PC Card 108
and the Gigaset USB Adapter 108 are examples of wireless network adapters.
A network adapter has a unique address, the
MAC
address.
