PPPoE (Point to Point Protocol over Ethernet) - A communications protocol
that combines the Ethernet and Point-to-Point Protocol (PPP) standards. PPPoE
is sometimes used with broadband modems.
PPTP (Point-to-Point Tunneling Protocol) - A protocol that lets a private
network connect securely to another private network through private "tunnels"
over the public Internet. This kind of interconnection is known as a virtual
private network (VPN).
protocol - A set of communication rules. When two computers or networks
use the same protocol, they can communicate with each other.
RIP (Routing Information Protocol) - A protocol used by a router to maintain
routing tables of configuration information to filter incoming and outgoing
traffic based on the IP addresses of the senders and receivers.
RJ-45 - RJ-45 jacks connect a computer to a router. In a wired network, one
end of a network cable is plugged into the RJ45 jack on a computer. The other
end of the cable is plugged into an RJ45 jack on a router. Data is passed to and
from the computer and router through the RJ45 jacks.
router - A hardware device that connects devices in a network. A router can
also provide Internet access to the networked devices.
RTS (Request To Send) - A signal sent by a receiving device, like a router, that
tells the sending device to begin transmission.
server - A computer that provides shared network service to a network. For
example, a server can provide file and printer sharing between networked
computers.
SSID (Service Set IDentifier) - In a wireless network, the SSID identifies a
network. All computer in the network must use the same SSID.
static IP address - An IP address that is permanently assigned to a device.
static routing - The routing of network information through a single, set path.
subnet mask - This number identifies what subnetwork the computer is located
on. This number is the same on all computers on a home network.
switch - Like a hub, a switch is a hardware device that links computers to create
a network. A switch provides better data routing than a hub.
TCP (Transmission Control Protocol) - A protocol used in connection with
Internet Protocol (IP) to let computers communicate over the Internet.
