Technology and Computers Trivia

1. What is the name of the structure on which cryptocurrency transactions are recorded and validated?

From Quiz Introduction to Cryptocurrency

Answer: Blockchain

Blockchain technology, as its name implies, consists in a chain of blocks in which transactions are recorded. Each of the blocks contains the data of the transaction(s), a timestamp, and two cryptographic hashes: the one from the previous block, and the closing hash of the current block, which will be used as a link to the following block. This mechanism contributes to the integrity of the transactions, given that any record contained within any block cannot be altered retroactively, without altering all the subsequent blocks. Blockchain is also a public distributed ledger, meaning that any user that has access to the network, through a valid node, can also have access to the blocks and the transactions that they contain, to explore them and validate them. While nowadays, blockchain is mainly associated with the cryptocurrency ecosystem, it is also used in other kinds of applications.

From Quiz What Is Cryptocurrency?

Answer: It uses encryption to verify the transaction.

The name cryptocurrency was chosen because it relies on encryption. The goal of each currency is to make the transaction as secure and safe as possible. Cryptocurrency does not have origins in the dark web and it is not terribly difficult to understand once the basic concepts are learned. We will go deeper into understanding how cryptocurrency works with the following questions.

From Quiz The Name Game

Answer: Apple

AOL, short for America Online, owns and operates web sites as well as providing news, entertainment, Internet access and Email service. Android is an operating system for mobile devices--it was developed by Google. AT & T, originally American Telephone & Telegraph, provides phone, data and TV service.

From Quiz Bird-Brain

Answer: Telephone

"H-e-l-l-o, how can I h-e-l-p you? Say or press 1 if you would like to pay your bill. I am sorry, I did not get that..." Most business phones are now answered by robots who cheerfully and mindlessly promise efficient assistance. Despite our irritation, a surprisingly large number of humans thank the robot or tell it to, "Have a nice day". Research shows that humans respond to voice and language cues even in an automated object. Many robots are programmed to transfer the call to a human Floor Manager if sensors detect a loud and angry voice. That surely happens a lot with these annoying buzzards.

From Quiz WATSON

Answer: Jeopardy

WATSON appeared on 'Jeopardy' three days in a row (the one game lasted three days). He went up against Ken Jennings and Brad Rutter, the two top 'Jeopardy' contestants at that time, and won one million dollars!

From Quiz What Is Cryptocurrency?

Answer: Peer to peer

Peer to peer is a transaction where two people can exchange money without having a trusted third-party server mediate the transaction. With traditional currency, banks often fulfill the role of guarantor of the transaction. In theory, quantum entanglement could one day play a part in cybersecurity, but that would require a complete remodel of the current system. By having the transaction peer to peer, cryptocurrency can be traded anywhere in the world where two computers can communicate. Most peer-to-peer transactions take about 10 to 15 seconds to be completed.

From Quiz Liar Liar

Answer: An experienced operator

An operator who knows how to read the results properly controls the test. These people are highly trained. The results are shown in a series of wavy lines on graph paper.

From Quiz Bird-Brain

Answer: Google

Google engineer Sebastian Thrun, co-inventor of Google "Street View", led the flock in design of the driverless car. His motivation was to save lives, save time, and save gas, by eliminating traffic congestion and accidents. Their robot-controlled car handled all kinds of traffic conditions and geography, though it was rear-ended at a stoplight. Nevada, Florida and California first legalized US driverless cars in 2012, with strict guidelines, and many unanswered questions about liability and ethics. For instance, if a car driven by a robot gets into an accident, who foots the bill? What if the silly goose does not have real-time road condition GPS (Global Positioning System) data, so it flies through a construction zone or into a pothole? Can someone hijack a driverless car?

From Quiz WATSON

Answer: IBM

IBM stands for International Business Machines. Its headquarters are in Armonk, New York. It was founded in 1911 and merged four companies.

From Quiz Liar Liar

Answer: To measure the rate of breathing

The witness or suspect is seated in a chair. This is to minimise moving. Large straps are placed on their chests to measure the rate of breathing. The speed of breathing going in and out shows nervousness. This may mean the person is worried or trying to hide something.

From Quiz Bird-Brain

Answer: Space

Space probe robots are good at repetitive, precise measurements and maneuvers, working alone without loneliness or complaint. They've been launched into distant space like Noah's birds, seeking land or life on the outer planets. A "probe" is specifically designed to take photographs and scientific research measurements during its long, one-way flight, but the information has to be sent back to humans for processing. The television series "Star Trek" used this beautiful theme: "Space: the final frontier...to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before." Much earlier, Captain James Cook and H.P. Lovecraft spoke similar words of adventure and desire.

From Quiz WATSON

Answer: Scientists downloaded documents onto him

The creators of WATSON downloaded thousands of documents onto WATSON. During Jeopardy, WATSON had no access to the Internet. WATSON can read electronic messages sent to him, but he can not read books like humans can. Putting WATSON through school would have been impractical and not efficient.

From Quiz What Is Cryptocurrency?

Answer: Bitcoin

Bitcoin was created and started by Satoshi Nakamoto in 2009. Very little is known about the inventor and some speculate that it may not be just one person but rather a group of people! The original concept was to incorporate peer-to-peer electronic currency exchange to remove the traditional bank. After mining the first "Genesis" block, Satoshi continued mining for just over a year and then backed away from the business entirely. It has been estimated that he/she mined close to a million coins in that year.

From Quiz Liar Liar

Answer: Monitor the perspiration of the witness/suspect

Wires are also fitted to the fingertips. These react to change in perspiration during the test. Most people seem to sweat more when they are nervous. If perspiration lifts in certain questions, the operator makes a note on the graph.

From Quiz Bird-Brain

Answer: Japan

Japan has an advanced comfort with robots, at home, school and industrial plants. The Japanese see robots as working alongside humans to create social and economic growth, and they view "objects" such as rocks or robots as non-human, yet having "spirit". Humanoid robots fit comfortably into the Japanese world view. In the West robots tend to be seen as "replacing" people by doing work for them, and as lifeless, repetitive hunks of metal without spirit (except lovable robot friends in the movies). As robots excel at "human" skills like language or providing comfort, Westerners struggle with the ethical question, "Then what is uniquely human?" (Naho Kitano, Waseda University). By 2004 Japan was far ahead of all other countries in numbers of robot companions throughout the culture. Honda has long been a world leader in design and placement of humanoid robots.

From Quiz WATSON

Answer: He comes up with hundreds of possible answers

WATSON's algorithms pull up hundreds of possible answers to any question. He then uses key words to narrow down his search. On Jeopardy, you could see WATSON's top three choices and how sure he was, represented by a percentage.

From Quiz Bird-Brain

Answer: Moth

Moths are night insects that blunder toward their goals, with sturdy thick bodies that can take the bashing. Made by Ecole Polytechnique Fderal De Lausanne ((EPFL) robot "Airburr" was similarly daffy. With no spatial-orienting equipment, it simply monitors its speed as it bounces off obstacles, recovers, and starts out again. If it falls, legs deploy it back into the air. In a chaotic, exploded or radioactive building, in a cave or in the dark, Airburr is the bird of the hour. Non-flying robots who clean household floors and swimming pools use a similar trial-and-error method. More sophisticated flying robots tend to be spatially confused by clutter, and disoriented in the dark.

From Quiz WATSON

Answer: Thomas J Watson, IBM's founder

IBM was the company that created WATSON, and it only seemed fitting they named it after the president, since WATSON was so smart and such a big project. WATSON proves what lots of smart people can do if they put their minds to it.

From Quiz Introduction to Cryptocurrency

Answer: Public

Pretty self explanatory, the public key, or address of the wallet, is visible to everyone, while the private is only viewable to the wallet's owner. The public key is what you need to know when transferring crypto to any wallet. For that matter, consider it as a bank account number: you need to enter the key to the wallet you wish to transfer to. Together with the private key, they serve as a means to validate the transactions in the crypto world. The public key also consists of a hash code, and it's generated automatically when the wallet is created. You have to be extremely careful when entering the address, because one single typo can send your funds to an unknown wallet, and it's pretty much impossible to trace them and get them back. Many of the apps offer an option to copy the address, or to retrieve it through a QR code, to minimize the risk of errors when transferring. The private key, on the other hand, is vital to the wallet's owner. It consists of a set of random words (12 to 24 on some wallets) that must be entered in the same order to grant full access to that wallet in any device. Needless to say, private keys are the main objective of hackers, since they can gain control of any wallet (and thus, any crypto contained within) by knowing their private keys. When using a hot wallet, the risk of theft of the private keys is increased, due to the wallet being constantly online. Having a wallet within a web-based exchange makes them even more vulnerable, as an attack on the whole site can target numerous wallets at once. Most web exchanges issue an explicit disclaimer about their responsibility for the safety of the funds of every user.

From Quiz What Is Cryptocurrency?

Answer: By providing the mathematical proof of a new block.

When each block is closed, there will be a new complex equation that has to be solved to balance the block and link it to all the blocks that come before it. These equations are so complex that it takes an entire building full of computer servers hours to weeks to solve the equation. Once the equation is solved the group that solves it is rewarded in crypto coins. There is competition to solve the same block, so there is an advantage to having the biggest and fastest computer rigs. The other groups who lose out do get paid service fees for the work they do.

From Quiz The Name Game

Answer: AMD

AMD is short for Advanced Micro Devices, Inc. It was founded in 1969 by businessman Jerry Sanders in Sunnyvale, California. Like Intel, based in Santa Clara, California, it is a publicly traded company. AMC is a major movie theatre chain. MCA stands for Motor Club of America. MDA apparently stands for the Muscular Dystrophy Association or Missile Defense Agency.

From Quiz Liar Liar

Answer: Baseline questions

The first questions that the witness or suspect is asked are baseline questions. This gives the operator an idea of how a person answers normally. Standard questions may be asked like their name, age, address and so forth. Sometimes, they will be asked to lie on purpose so that the operator will know what a false answer sounds like. This makes it easier to see when they are lying.

From Quiz Bird-Brain

Answer: New threats did not compute

Robots are stymied when they encounter unfamiliar threats, or those that quickly change. Military robots reduce workload, reduce human presence, and lessen danger to humans. They roll out ahead of troops, using sensors, lasers and cameras to locate enemies, and then collect data on enemy numbers and strength. The "Stryker" light armored vehicle was one of dozens of robots the Army tested. The problem was soldiers said they felt out-of-control and irritated when the robot took full control, and robots couldn't be relied upon to interpret changed or new threats with accuracy.

From Quiz WATSON

Answer: DeepQA

The goal of the DeepQA project is to build a machine that successfully understands and communicates in the human, or natural, language, as opposed to computer language. I believe WATSON meets those requirements, how about you?

From Quiz What Is Cryptocurrency?

Answer: They use two-factor authentication.

Using two-factor authentication is simpler than you might think. When you wish to buy or sell cryptocurrency, a security code will be sent to the email you provide. You then must correctly supply the security code to establish you are indeed tied to that email address. The other person doing the transaction must complete the same process. Of course, there is always a possibility that the person on the other end is not honest, so like any internet transaction caution is always advised. No background checks or preapprovals are required to trade cryptocurrency.

From Quiz Bird-Brain

Answer: Ask a security question

Most automated spambots cannot answer a security question such as, "What is your father's middle name?" Spambots are also bamboozled by email that requires a reply to confirm their intention, by words in inconsistent print size, and by heavily scripted words. Still, over the course of a typical year the bots sent out more than seven trillion spam messages. Spambots got their name from a Monty Python comedy sketch, where unwanted spam (a precooked pork meat in a can) appeared in every dish.

From Quiz WATSON

Answer: In an electronic text

WATSON receives electronic texts containing questions to be asked of him. He cannot hear or read things in our world.

From Quiz Introduction to Cryptocurrency

Answer: Minting

To mint an NFT, you need to select the network on which it will be hosted, and use a wallet that supports that network. You will then be prompted to upload the media file to the wallet, and you will also need to have an amount of coins enough to cover the fees of the transaction. It sounds a bit confusing, but certain crypto sites are specialized in this type of transaction, and will guide you step by step in a very simple way.

From Quiz Liar Liar

Answer: Many writings

The word poly is Greek for many. For example, Polynesia means many islands. The word graph comes from the Greek word graphein, meaning to write. For example, graphology means the study of handwriting. Therefore, polygraph means many writings. This is because everything is recorded during a polygraph test, so there are 'many writings'.
