DEFINITION
communications.
A device that divides the signal from an input cable between
two or more cables.
The Service Set Identifier or network name is a unique
identifier that wireless clients use to associate with an
access point to distinguish between multiple WLANs in the
same area. All clients on a WLAN must have the same SSID
as the access point.
A type of firewall that tracks each connection, traversing all
firewall interfaces to ensure validity. In addition to examining
the source and destination in the packet header based on static
rules, a stateful inspection firewall:
•
Examines packet headers via the context established by
previous packets that traversed the firewall
•
Monitors the connection state and saves it in a table
•
Closes ports until a connection to a specific port is
requested
•
May examine the packet contents up through the
application layer to determine more than just the source
and destination
A stateful inspection firewall is more advanced than a static
filter firewall.
A type of firewall that examines the source and destination in the

A bit mask that is logically ANDed with the destination IP address
of a packet to determine the network address. A router routes
packets using the network address.
A part of a network; commonly abbreviated "subnet. " When
subnetting is used, the host portion of the IP address is
divided into a subnet and host number. Hosts and routers
use the subnet mask to identify the bits used for the network
and subnet number.
On an Ethernet network, a switch filters frames based on the
