10Network congestion
The state of a network when the demand on resources exceeds the available capacity.
11Bandwidth
A measure of the data carrying capacity of the media.
12bandwidth
a measure of the data carrying capacity of the media
13fault tolerance
a method of limiting the impact of a hardware or software failure on the network
14congestion
a state where the demand on the network resources exceeds the available capacity
15QoS
a set of techniques to manage the utilization of network resources
16BYOD
bring your own device, a trend in networking where users are allowed to use personal devices and tools on business and campus networks
17converged network
one in which multiple technologies such as data, telephone, and video are all delivered on the same network infrastructure
18cloud computing
allows users to access applications, back up and store files, and perform tasks without needing additional software or servers
19powerline networking
adds the ability to connect a device to the network using an adapter wherever there is an electrical outlet
20identity theft
capturing of personal data that leads to identity theft
21minimum security requirements
implementing a firewall and installing antivirus software
22intermediary devices
they direct data along alternate pathways when there is a link failure
23podcast
an audio-based medium that allows people to deliver their recordings to a wide audience
24social media
interactive websites where people create and share user-generated content with friends and family
25wiki
web pages that groups of people can edit and view together
26instant messaging
real-time communication between two or more people
27DSL
an always-on, high bandwidth connection that runs over telephone lines
28Cable
uses the same coaxial cable that carries television signals into the home to provide Internet access.
29Dialup telephone
much slower than either DSL or cable, but is the least expensive option for home users because it can use any telephone line and a simple modem.
30Satellite
requires a clear line of sight and is affected by trees and other obstructions.
31The Internet
a network based on Ethernet technology.
32Ensuring confidentiality
only the intended recipients can access and read the data.
33Maintaining integrity
the assurance that the information has not been altered during transmission.
34Ensuring availability
the assurance of timely and reliable access to data.
35Data integrity
verifies that the data has not been altered on the trip between the sender and the receiver.
36VPNs
are not the only secure method by which data can be transferred confidentially.
37Online shopping
requires access to the Internet.
38Strong, complex passwords
support data confidentiality.
39LANs and WANs
both connect end devices.
40WANs
connect LANs at slower speed bandwidth than LANs connect their internal end devices.
41Converged network
a single network channel capable of delivering multiple communication forms.
42Network that supports QoS
provides predictable levels of service to different types of traffic.
43Circuit-switched networks
if all circuits are busy, a new call cannot be placed.
44Congestion
a state where the demand on the network resources exceeds the available capacity.
45TelePresence
provides real-time video and audio communication over the Internet for corporate meetings.
46Minimum required security protection for home users
includes antivirus software, antispyware software, and a firewall.
47Criteria for selecting network media
include the distance the media can successfully carry a signal and the environment where the media is to be installed.
48Fault tolerance
is shown when students experience only a very short interruption of network services after a fiber optic cable is damaged.
