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 area networks (LAN) and wide area networks (WAN).

Network adapter

The network adapter is the hardware device that implements the connection of a net-

work component to a local network. The connection can be wired or wireless. An Ether-

net network card is an example of a wired network adapter. The Gigaset USB Adapter

300 is an examples of a wireless network adapter.

A network adapter has a unique address, the MAC address.

Protocol

A protocol describes the arrangements for communicating on a network. It contains

rules for opening, administering and closing a connection, for data formats, time

frames and error handling. The TCP/IP protocols are an example of protocols used for

communication within a network.

RC4

RC4 is an encryption algorithm on which WEP and TKIP encryption are based. Special

features of this algorithm are a secret key and variable key length.

Roaming

Roaming extends the range of a wireless LAN with several Access points that use the

same SSID and the same radio channel and are linked via Encryption. 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 via Encryption or WLAN technology to

the Internet.

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 a Dynamic IP address, a static IP address never changes.
