local area network to use one set of IP addresses for internal traffic and
a second set of IP addresses for external traffic. This allows a company

internal local addresses into globally unique IP addresses before send-
ing packets to the outside network.
NIC Network Interface Card is a circuit board installed in a PC that
provides the interface between a communicating PC and the network.

(usually) user data. A continuous sequence of binary digits of informa-
tion is switched through the network and an integral unit.
Packet Filtering Security established through the use of a set of filter
rules that operates by examining IP packets to allow them to pass or
not. A router that implements packet filtering is known as a screening
router or firewall router.

work to a particular address and echoed back to confirm that a particu-
lar site can be reached via the network.
