PPPoE
(Point to Point Protocol over Ethernet) – A method used mostly by
DSL providers for connecting personal computers to a broadband modem for
Internet access. It is similar to how a dial-up connection works but at higher
speeds and quicker access.
PPTP
(Point-to-Point Tunneling Protocol) – A protocol (set of communication
rules) that allows corporations to extend their own corporate network through
private “tunnels” over the public Internet. Effectively, a corporation uses a
wide-area network as a single large local area network. A company no longer
needs to lease its own lines for wide-area communication but can securely
use the public networks. This kind of interconnection is known as a virtual
private network (VPN).

anywhere in the network.

the TCP/IP protocol suite. It determines a route based on the smallest hop
count between source and destination. RIP is a distance vector protocol that
routinely broadcasts routing information to its neighboring routers and is
known to waste bandwidth. AppleTalk, DECnet, TCP/IP, NetWare, and
VINES all use incompatible versions of RIP.
RJ-11
(Registered Jack-11) – A telephone connector that holds up to
six wires. The RJ-11 is the common connector used to plug a telephone
