data within a specific context to produce actionable insight for end users.
End users - ANSWERPrivate persons or institutional decision makers that use
information and applications provided by other stakeholders
Cybersecurity - ANSWERPractice of protecting information systems, networks, data
and programs
Cyberspace - ANSWERNetwork of hundreds of thousands of interconnected
computers, servers, routers, switches and fiber optic cables that allow vital
infrastructures to work
Digital - ANSWERTechnologies that generate, store and process data as fixed
numbers; binary digits or bits in the form of 0's and 1's
Information systems - ANSWERCombinations of hardware, software and networks
that are integrated together to collect, process, store and distribute data
,Information broker - ANSWERModule used to store IoT data received from sensors
or from the cloud
Internet - ANSWERGlobal network of wired and wireless networks
Web - ANSWERInformation space consisting of a number of public resources that are
linked together and made accessible via the internet
Cyber terrorists - ANSWERUses cyberspace to disrupt critical infrastructures to elicit
widespread panic and loss of public confidence in the ability of government to
function effectively, such as by interrupting critical infrastructure
Consumer IoT - ANSWERAll the user's networks around their personal and home
devices
Industrial IoT - ANSWERMachines, computers and people enabling intelligent
industrial operations using advanced data analytics for transformation business
outcomes
Internet of Bodies (IoB) - ANSWERConnected devices that monitor the human body,
collect physiological, biometric, or behavioral data and exchange information of a
wireless or hybrid network. Can be implanted, swallowed or worn.
Wireless Personal Area Network (WPAN) - ANSWERShort-distance network that
allows multiple devices within a small area to connect to each other.
Examples of a WPAN are Bluetooth and Zigbee.
Sensors - ANSWERDevices that respond to inputs from the physical environment and
use those inputs for decision-making by displaying the inputs, transmitting them for
additional processing, or using them in conjunction with artificial intelligence
Sensor data - ANSWERMeasurements of some physical property. Data has values, a
time and location. There are fixed and mobile sensors.
Actuator - ANSWERDevice that converts an electrical signal into a corresponding
physical quantity such as movement, force, or sound
IoT devices - ANSWERSimple networked devices such as sensors and actuators that
are installed close to the data source or control interfaces. Usually connected via 3G,
4G, 5G, Wi-Fi, PCIe, USB or Ethernet within an edge computing application scenario.
Edge processing - ANSWERA process of data aggregation, manipulation, bandwidth
reduction, and other logic directly on an IoT sensor or device
Access network - ANSWERPart of a network which is concerned with moving data to
and from a sensor or edge device to a backhaul network
, Gateway - ANSWERBuilding block used to move collected data (from sensors) to the
central IoT platform.
LPWAN (Low Power Wireless Area Network ) - ANSWERLower than 1 GHz, 868 MHz
in EU called ISM (Industrial, Scientific, and Medicine) band,
USA 915 MHz
Several techs that use this band are Sigfox, LoRaWAN, and Weightless
LPWANs have lower data rates compared to normal cellular ones
WLAN (Wireless Local Area Network) - ANSWERGroup of collocated computers or
other devices that form a network based on radio transmissions rather than wired
connections
What are the 4 things to consider when choosing IoT connectivity? - ANSWERData
rate, power availability, range, cost
Customer Edge Device - ANSWERDevices that receive data from and send commands
to IoT devices.
Mobile Edge Computing (MEC) - ANSWERComputer node that focuses on data
aggregation, compression and transformation. The ___ server may suffer from
resource limitation.
Centralized IoT platform - ANSWERPowerful central storage and processing
capability for IoT use cases such as data interoperability and uniform data access.
Handles management of IoT devices for remote management.
UNB (Ultra-Narrow Band) - ANSWERSystems transmit the signal in a small amount of
spectrum, usually less than 1 kHz, and are particularly suitable for small amounts of
data
Spread spectrum - ANSWERTechnique in which the signal is transmitted on a
bandwidth that is much bigger than the original frequency to decrease interference
and increase security
LoRaWAN - ANSWERbased on LoRa protocol from Semtech.
is asynchronous and uses Spread spectrum.
Suitable for dense deployments such as buildings or cities.
Zigbee - ANSWERShort-ranged network with meshing
SigFox - ANSWERNamed for company that owns it.
Used in Narrowband (200 kHz)
Suitable for dense deployments such as buildings or cities.
Weightless - ANSWERConsists of three protocols, works on 2.4
