Tech Trends Flashcards
What is meant by the term, “Personal Cloud?”
The individual’s collection of digital content, services, and apps which are seamlessly accessible across any devices
What factors/technologies/megatrends are enabling Personal Cloud?
Consumerization
Appification
Mobility
Ubiquitious Cloud
Client Virtualization
Regarding “consumerization”… consumers are very good at _________ technology, but very bad at __________ technology. How does the cloud solve that problem?
Choosing; Managing
What four “key actions” will we expect from our personal cloud? What does each mean?
- Sync me-Synced on every device
- See me-Knows where you are and adapts
- Know me-Interprets requests based on its knowledge of you and your preferences
- Be me-Cloud acts on your behalf
What is the “Internet of Things” (IoT)?
The interconnection via the internet of computing devices embedded in everyday objects, enabling them to send and receive data.
Be able to explain how Moore’s Law helped make the IoT possible.
Law of transistors on a chip doubles every two years..at the same prices
For a fixed amount of power, computers become much cheaper
Why do businesses put sensors on “things”?
Can get data from them to assist in decision making
Be able to explain one of the real-world examples of IoT technology in action from the lecture.
Transportation
Powerful communication systems and data from the car itself
Uses cellular 5G data
If you get in a car accident and airbag is deployed, it sends info so help can be dispatched
Alerts if there’s a car accident 20 cars ahead of you
What is “GeoFencing?”
You establish a fence, if your package gets out of that fence, you get alerted so that you take proper action.
What is “Blockchain”?
Distributed ledger system that enables trusted transaction in an untrusted environment
Provides increased trust in an environment of untrust
What is “Bitcoin?”
A digital currency featuring a peer-to-peer network that allows users to send units of the currency to each other online without the use of a traditional institution.
What are the four components to a Blockchain system?
Distributed ledger
Miners
Wallet
Smart contracts
Distributed ledger
A list of transactions on servers
Adds trust to an untrusted environment because trusted transactions are logged in servers.
Ex. Bitcoin address A sent x bitcoins to Bitcoin address B
Miners
Systems that are trusted to add transactions to the ledger
Process:
Transactions placed in a block – 10 MINUTES
Miners compete to secure the new block
Calculate cryptographic “harsh” that immutably links adjacent blocks
Single winner — validated by consensus
Winning block propagated across entire system
Wallet
End-User interface to Bitcoin system (wallet)
Functions:
o Propose new transactions
o Read the transaction ledger
Smart contracts
Code with a transaction
Takes actions based on conditions
Runs as long as it has money
Why do Blockchain systems have distributed ledgers?
Multiple copies that are publicly readable
How do Smart Contracts work?
Code within a transaction that takes actions based on conditions; runs as long as it has money
What is “provenance?” How does blockchain address provenance?
Fancy way to say where did it come from and what origin did it come from?
Adds trust to an untrusted environment
What is a “deep fake”?
The use of artificial intelligence to create an image/video/audio that looks real even though it isn’t
What is “reality apathy”?
Situation where it’s just too much to figure out what’s real from fake and then just resort to previous beliefs
How could blockchain be used to combat deep fakes?
Tagging photos and videos as authentic when they’re developed
would be able to see if it was fake or not by using provenance
What is a “stablecoin” and how is it different from Bitcoin?
Bitcoin is based on value on how much people will pay for them (intrinsic value)
Stablecoin is a cryptocurrency whose value is pegged either to one or multiple national currency to reduce volatility
