NIC
(Network Interface Card) – A board installed in a computer
system, usually a PC, to provide network communication
capabilities to and from that computer system. Also called an
adapter.
NTP
(Network Time Protocol) - is a protocol used to synchronize
computer clock times in a network of computers.
Packet Filtering
- Discarding unwanted network traffic based on
its originating address or range of addresses or its type (e-mail,
file transfer, etc.).
PCI
(Peripheral Component Interconnect) – A peripheral bus
commonly used in PCs, Macintoshes and workstations. It was
designed primarily by Intel and first appeared on PCs in late
1993. PCI provides a high-speed data path between the CPU
and peripheral devices (video, disk, network, etc.). There are
typically three of four PCI slots on the motherboard. In a
Pentium PC, there is generally a mix of PCI and ISA slots or PCI
and EISA slots. Early on, the PCI bus was known as a “local
bus.” PCI allows IRQs to be shared, which helps to solve the
problem of limited IRQs available on a PC. For example, if
there were only one IRQ left over after ISA devices were given
their required IRQs, all PCI devices could share it. In a PCI-only
machine, there cannot be insufficient IRQs, as all can be shared.
PCMCIA
- The PCMCIA (Personal Computer Memory Card
International Association) is an industry group organized in 1989
to promote standards for a credit card-size memory or I/O device
that would fit into a personal computer, usually a notebook or
laptop computer.
Peer-to-Peer Networking
– Allows users to share local
resources between PCs without needing an access point or
router.

Ping
(Packet Internet Groper) – An Internet utility used to
determine whether a particular IP address is online. It is used to
test and debug a network by sending out a packet and waiting for
a response.
Plug-and-Play
– The ability of a computer system to configure
expansion boards and other devices automatically without
requiring the user to turn off the system during installation.
Port
– A pathway into and out of the computer of a network
device such as a switch or router. For example, the serial and
parallel ports on a personal computer are external sockets for
plugging in communications lines, modems, and printers.
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
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
