what content to send to the
server. It also checks the caching server
for a copy of requested content before
going to the original source if a copy is
not there.

stores a local copy of content requested
from another source (such as an
Internet server) and retains it for a
specified amount of time.

Allows multiple devices in a
common pool to use the same IP address.

a network into divisions, designed in such
a way that if one section of a network is
brought down, the other sections of the
network will not be directly affected.

of software designed to monitor network
connections.

Any type of software
that e~bles a computer to connect
to a network or another computer,
either remotely or locally.

Events, conditions, and limits in
a network that contribute to the slow
delivery of data, called latency.
delays

of what devices and cables you have on
your network, how the network is configured,
where it is located, and policies
and procedures used to manage and
maintain the network.

The amount of rime a network
and/or network device is not functioning.
downtime
Software applications intended
to both entertain and educate the
people who use them.
edutainment
Data files that a system uses to
record errors, warning, and informational
messages generated by operating
system components or applications.
event logs
An application or component
found on all current versions of
Windows that centralizes all event logs
on a local computer.
Event Viewer
A network’s ability to have a
portion of itself fail but to still continue
to work at some level of functionality.
fault tolerance
A goal or concept in
network optimization that refers to
the ability to keep a network up and
running reliably with the least amount
of downtime possible.
high availability
A network
application that requires a lot of
bandwidth to function.
high bandwidth application
Data files that contain an
ongoing record of the activity in a
specific device or on the network.
history log
The difference in the amount of
time that two packets take to reach the
same destination due to network delays.
jitters
The time it takes a data packet
to move from one designated network
location to another.
latency
A measurement of how
well a program or network device can
handle latency.
latency sensitivity
A testing methodology that
consists of deliberately purring greater
than normal demands on a network or
the devices on a network to see how
they will perform.
load testing
A diagram that
shows how everything works on the
network.
logical network diagram
Whatever carries communications
physically across a network, such as copper
wires, radio signals, or fiber optic cables.
media
An important piece of
documentation that shows either the
physical layout of a network or its logical
layout.
network diagram
A collective term
for various actions, procedures, and
methods related to monitoring, configuring,
maintaining, supporting,
and updating a network and its infrastructure.
network management
The act of observing
a network’s activity and determining its
current state.
network monitoring
The process of
striking a balance between network performance
and network cost.
network optimization
A program or
service thatuses conventional data communications
technologies and networks
to carry video over IP.
network video application
The chance
that a packet will be dropped while it is
moving across a network.
packet drop probabilities
The specific practice of
limiting packet types, sources, or content
as the means to do bandwidth shaping.
packet shaping
In networking, an analysis of
how well the network is currently functioning
and what can be done to make
it function better.
performance
A document
that shows where everything on the
network is physically located.
physical network diagram
A component of network
management that concerns how the
network is documented.
policy
A component of network
management that lays out how the
network should be maintained, what
should happen should failure or
other such issues occur, and how to
implement established policies.
procedure
The amount of time required
for a packet to travel to its destination.
propagation
The mechanisms
that allow a network to reserve
resources and control how those
resources are distributed.
quality of service (QoS)
A fault tolerance technique
in which a network has standby components
online and running, so that
if a main component ails, the redundant
component can pick up the load
seamlessly.
redundancy
Rules and guidelines imposed
on the company by outside agencies
and/or organizations.
regulations
A term referring to likelihood
thata network will function properly
over a given time period.
reliability
A type of diagram that uses
graphic symbols rather than realistic
pictures to depict the elements of a
computer or network system.
schematics
A type of application that is
designed to test the amount of data passing through a network in a specific amount of time.
speed test
A condition in which a
packet has to be temporarily stored
before it can be transmitted.
storage delay
A testing method in which
administrators deliberately load networks
or devices beyond the point
where they can function properly, to see
what will happen.
stress testing
Data files maintained by the
operating system or components of
the operating system that record information
about system changes, device
changes, system events, driver changes,
and other similar types of information.
system logs
A program or device
that is designed to test the amount of
data passing through a nerwork in a
specific amount of time. See speed test
or speed tester.
throughput tester
A technique for nerwork
optimization in which traffic is prioritized
based on what type of packet
is passing through the nerwork. Also
known as bandwidth shaping.
traffic shaping
The act of sending data
across a nerwork connection.
transmission
The measure of how long a
nerwork and/or its devices have been
functioning without any outages or
shutdowns.
uptime
A type of application
that uses conventional data
communication technologies and
nerworks to carry video over IP.
video application
Nerwork communications
applications which are
used to communicate using video
transmissions.

A nerwork application
which uses cameras to record what
is happening in a specific area and
transmit the image to a central server
location.
video surveillance
The process by which an
operating system and/or network is
converted inro a software construct
that runs inside a host environment
independent of the hardware platform
being used ro support it.
