PPPoE
Point-to-Point over Ethernet is a protocol for connecting remote hosts to the
Internet over an always-on connection by simulating a dial-up connection.
Router
A device that forwards data packets along networks. A router is connected to at
least two networks, commonly two LANs or WANs or a LAN and its ISP
network. Routers are located at gateways, the places where two or more
networks connect.
Subnet Mask
A mask used to determine which subnet an IP address belongs to. An IP
address has two components, the network address and the host address.
Subnetting enables the network administrator to further divide the host part of
the address into two or more subnets.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol), the suite of
communications protocols used to connect hosts on the Internet.
VPN
Virtual private networks are secured private network connections, built on top of
publicly accessible infrastructure, such as the Internet or the public telephone
network. VPNs typically employ some combination of encryption, digital
certificates, strong user authentication and access control to provide security to
the traffic they carry. They usually provide connectivity to many machines
behind a gateway or firewall.
WAN
Wide Area Network, a communication network that covers a relatively broad
geographic area, consisting of two or more LANs. Broadband communication
over the WAN is often through public networks such as the ADSL or Cable
systems, or through leased lines or satellites. To simplify it, please image
network as a WAN.
WEP
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a
64/128-bit shared key algorithm, as described in the IEEE 802.11 standard.
