Questions And Correct Detailed Answers
(Verified Answers) |Brand New Version!!
Industrial Internet Consortium (IIC) - ANSWER>>a nonprofit organization created for the
promotion of open standards and interoperability for technologies used in industrial and
machine-to-machine (M2M) environments
Internet of Things Security Foundation (IoTSF) - ANSWER>>a collaborative, nonprofit,
international response to the complex challenges posed by cybersecurity in the expansive
hyper-connected IoT world
standards developments organizations (SDOs) - ANSWER>>organizations that work to
formulate health and safety standards
Distributed Ledger Technology (DLT) - ANSWER>>a decentralized database managed by
multiple participants across multiple nodes
Blockchain - ANSWER>>represents one of the most suitable candidate technologies capable of
maintaining an immutable log of transactions (a ledger) in a distributed network, building a
truly decentralized, trustless, and secure environment for transactions and related applications.
Smart Contract - ANSWER>>a software component running on the Blockchain to implement an
agreement between two or more parties, triggered automatically when certain conditions are
met.
Trustless - ANSWER>>not requiring trust, because the structure prevents dispute
PoW - ANSWER>>Proof of Work. Algorithm for blockchain consensus
Two types of DLT - ANSWER>>Permissionless and permissioned
, Consortium/Federated DLT - ANSWER>>Permissioned network shared across multiple
organizations. Can be supervised or self-regulated.
Four key features of Blockchain - ANSWER>>Decentralization, Immutability, Auditability, Fault
tolerance and resilience
Hash pointer - ANSWER>>points to where the last block in the blockchain is. Has a
cryptographic hash for validation and prevents alteration
Required to send information between blockchain notes - ANSWER>>public-private key pair
Consensus Algorithm - ANSWER>>Systems based on state machine replication that make sure
all of the replicas for the state are always synchronized and updated
Benefits for DLT on the IoT - ANSWER>>Trust, resilience, adaptability, fault tolerance, security,
complete decentralization
Challenges for DLT on the IoT - ANSWER>>scalability, storage, latency, security, privacy,
environmental impact, compliance
Three primary IOT metrics - ANSWER>>Volume, variety, velocity
California Consumer Privacy Act (CCPA) - ANSWER>>a state statute intended to enhance privacy
rights and consumer protection for residents of California in the United States
National Cybersecurity Center of Excellence (NCCoE) - ANSWER>>a U.S. government
organization that builds and publicly shares solutions to cybersecurity problems faced by U.S.
businesses
cybersecurity - ANSWER>>the practice of protecting information systems, networks, data, and
programs from digital attacks
cyberspace - ANSWER>>a network of hundreds of thousands of interconnected computers,
servers, routers, switches, and fiber-optic cables that allow critical infrastructures to work
digital - ANSWER>>technologies that generate, store, and process data as fixed numbers; binary
digits or bits in the form of zeroes and ones
