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).
Print Server – A hardware device that enables a printer to be located
anywhere in the network.
RIP (Routing Information Protocol) – A simple routing protocol that is part of
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 into
a wall.
RJ-45 – A connector similar to a telephone connector that holds up to eight
wires, used for connecting Ethernet devices.

Router – Protocol-dependent device that connects sub networks together.
Routers are useful in breaking down a very large network into smaller sub
networks; they introduce longer delays and typically have much lower
throughput rates than bridges.
Server – Any computer whose function in a network is to provide user
access to files, printing, communications, and other services.
Signal Strength – Determines the strength of the signal for each wireless
channel.
Software – Instructions for the computer. A series of instructions that
performs a particular task is called a “program.” The two major categories of
software are “system software” and “application software.” System software
is made up of control programs such as the operating system and database
management system (DBMS). Application software is any program that
processes data for the user.
A common misconception is that software is data. It is not, software tells the
hardware how to process the data.
SOHO (Small Office/Home Office) – Market segment of professionals who
work at home or in small offices.
Static IP Address – A permanent IP address that is assigned to a node in
a TCP/IP network.
