802.1X |
A port-authentication network access control mechanism for networks. |
|
|
802.11a |
A wireless standard that operates in the frequency range of 5 GHz and offers throughput of up to 54 Mbps. |
|
|
802.11a-ht |
802.11a-ht, and the corresponding 802.11g-ht standard, are technical terms for mixed mode 802.11a/802.11g operation. In mixed mode, both technologies are simultaneously supported. |
|
|
802.11b |
The first popular wireless standard, operates in the frequency range of 2.4 GHz and offers throughput of up to 11 Mbps. |
|
|
802.11g |
Currently (2015) the wireless standard with the widest use, operates on the 2.4-GHz band with a maximum throughput of 54 Mbps. |
|
|
802.11g-ht |
802.11g-ht, and the corresponding 802.11a-ht standard, are technical terms for mixed mode 802.11a/802.11g operation. In mixed mode, both technologies are simultaneously supported. |
|
|
802.11i |
A wireless standard that added security features. |
|
|
802.11n |
An updated 802.11 standard that increases transfer speeds and adds support for multiple in/multiple out (MIMO) by using multiple antennas. Can operate on either the 2.4- or 5-GHz frequency band and has a maximum throughput of 400 Mbps. |
|
|
ad hoc mode |
A wireless networking mode where each node is in direct contact with every other node in a decentralized free-for-all. Is similar to the mesh topology. |
|
|
Advanced Encryption Standard (AES) |
A block cipher created in the late 1990s that uses a 128-bit block size and a 128-, 192-, or 256-bit key size. Practically uncrackable. |
|
|
bandwidth saturation |
When the frequency of a band is filled to capacity due to the large number of devices using the same bandwidth. |
|
|
Basic Service Set |
In wireless networking, a single access point servicing a given area. |
|
|
Bounce |
A signal sent by one device taking many different paths to get to the receiving systems. |
|
|
bring your own device (BYOD) |
A trend wherein users bring their own network-enabled devices to the work environment. These cell phones, tablets, notebooks, and other mobile devices must be easily and securely integrated and released from corporate network environments using on-boarding and off-boarding technologies. |
|
|
carrier sense multiple access with collision avoidance (CSMA/CA) |
Access method used mainly on wireless networks. Before hosts send out data, they send out a signal that checks to make sure the network is free of other signals. If data is detected on the wire, the hosts wait a random time period before trying again. If the wire is free, the data is sent out. |
|
|
dipole antenna |
The standard straight-wire antenna that provides most omnidirectional function. |
|
|
link state |
Type of dynamic routing protocol that announces only changes to routing tables, as opposed to entire routing tables. Compare to distance vector routing protocols. |
|
|
point-to-point |
Network topology in which two computers are directly connected to each other without any other intervening connection components such as hubs or switches. |
|
|
point-to-multipoint |
Topology in which one device communicates with more than one other device on a network. |
|
|
site survey |
A process that enables you to determine any obstacles to creating the wireless network you want. |
|
|
thick client |
A wireless access point that is completely self-contained with a full set of management programs and administrative access ways. Each client is individually managed by an administrator who logs into the WAP, configures it, and logs out. |
|
|
thin client |
A wireless access point with minimal configuration tools installed. Instead, it is managed by a central controller. An administrator can manage a large number of thin clients by logging into the central controller and performing management tasks on any thin client routers from there. |
|
|
unidirectional antenna |
focus all of their transmission energy in a single, relatively narrow direction. Similarly, their design limits their ability to receive signals that are not aligned with the focused direction. |
|
|
VLAN Pooling |
Used in wireless networking, a setup where multiple VLANs share a common domain. The multiple VLANs are used to keep broadcast traffic to manageable levels. Wireless clients are randomly assigned to different VLANs. Their common domain enables them all to be centrally managed. |
|
|
wireless bridge |
Device used to connect two wireless network segments together, or to join wireless and wired networks together in the same way that wired bridge devices do. |
|
|
wireless controller |
Central controlling device for thin client WAPs. |
|
|
Out-of-band management |
The process of managing a network device via a connection other than the regular network link used by the device to send and receive network traffic |
|
|
Bluesnarfing |
The practice of gaining unauthorized access to a Bluetooth device |
|
|
Bluejacking |
The practice of sending unsolicited messages over Bluetooth |
|
|
TEMPEST |
protects against unintentional signal leakage and eavesdropping |
|
|
(UTM) Unified Threat Management |
a network security solution combining the functionality of a firewall with additional safeguards such as URL filtering, content inspection, or malware inspection |
|
|
Virtual Wire |
solution that allows for creating logical binding between two ports and passing all traffic between them without any switching or routing |
|
|
eDiscovery |
the process of searching, collecting, and securing electronic data with the intent of using it in a legal proceeding or investigation |
|
|
ping host1 -6 |
syntax for checking the IPv6 connectivity with another network node (host1) in MS Windows |
|
|
ping6 host1 |
