PPPoE
Point-to-Point Protocol over

Ethernet

PPPoE is a

Protocol

for connecting network components in a local Ethernet network to

the

Internet

via a modem.

PPTP
Point-to-Point

Tunneling

Protocol

An

Internet

connection using PPTP

Protocol

that creates a "tunnel" within an Internet

connection for a secure private connection in which the data are sent in encrypted form.

The PPTP protocol is used in a Virtual Private Network (

VPN

).

Private IP address
The private

IP address

is a network component's address within the local area network

(

LAN

). The network operator can assign any address he or she wants. Devices that act

as a link from a local network such as the Gigaset SE505 dsl/cable have a private and a

Public IP address

.

Protocol
A protocol describes the agreements for communication on a network. It contains rules

for opening, administering and closing a connection, about data formats, time frames

and error handling. Communications between two applications require different

protocols at various levels, e.g. the

TCP/IP

protocols for the

Internet

.

Public IP address
The public

IP address

is a network component's address on the

Internet

. It is assigned by

the

Internet Service Provider

. Devices that create a link from a LAN to the Internet, such

as the Gigaset SE505 dsl/cable, have a public and a

Private IP address

.

Remote Management
Remote Management refers to the ability to manage a network from a network

component that is actually outside the local area network (

LAN

).

Roaming
With Roaming, the range of a wireless LAN is increased by using several

Access points

that use the same

SSID

and radio channel and which are interconnected by an

Ethernet

.

The PC's within the network can switch dynamically between several Access Points

without losing an existing network connection.
Router
A router directs data packets from one local area network (

LAN

) to another via the

fastest route. A router makes it possible to connect networks that have different

network technologies. 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

application that provides a particular service such as

DNS

or a Web service.
