Bits & Bytes: Week V - IV - Wireless Network Configurations, Channels, and Security) Flashcards
This type of wireless network doesn’t typically have any network infrastructure. Nodes within range all speak directly to each other.
Ad-hoc Network
Sharing data between smartphones, communication between equipment in a warehouse, and communication during a disaster event are examples of when __ _________ network might be used.
Ad-hoc network
What is the most common type of wireless network used in business settings?
A WLAN
ACRONYM:
WLAN
Wireless Local Area Network
This type of wireless network consists of mostly wireless access points which are connected to a wired network wirelessly.
a Mesh Network
Individual, smaller sections of the overall frequency band used by a wireless network
Channels
What 3 channels never overlap on n 802.11b network?
Channels 1, 6, and 11
If a channel operates at 2412 megahertz and has a width of 22 megahertz, what are its range of frequencies?
2401 - 2423 megahertz
ACRONYM:
WEP
Wired Equivalent Technology
What is a wireless encryption technology that only provides a very low level of privacy?
Wired Equivalent Technology provides as much security as sending unencrypted data over a wired network
In data encryption, what correlates with a higher level of security?
Longer keys (or more bits)
How many bits is in a WEP encryption key?
40 bits
ACRONYM:
WPA
WiFi Protected Access
How many bits are in a WPA encryption key?
128 bits
What is the most commonly used encryption algorithm for wireless networks?
WPA2
How many bits are in a WPA2 encryption key?
256 bits
Configuring WAPs to only allow for connections from a specific set of trusted MAC addresses is known as what?
MAC filtering
What’s another term for cellular networking?
Mobile networking
What is a major difference between cellular and wifi signals?
Cellular signals can travel over much longer distances more easily.
This protocol is an interoperable, wireless, Radio Frequency (RF)-based communications technology designed specifically for control, monitoring and status reading applications in residential and light commercial environments
Z-Wave Protocol
This wireless protocol is the only complete loT solution, from the mesh network to the universal language that allows smart objects to work together
Zigbee Protocol
This wireless protocol is built for the complexities of the IoT, addressing challenges such as interoperability, security, power, and architecture requirements. It is a low-power wireless mesh networking protocol based on the universally supported Internet Protocol (IP), and built using open and proven standards.
Thread Protocol
