(2010 Flash Crash") An example of the consequences of our dependency on computers was the so-called "flash crash " which occurred on May 6, 2010, when the U.S. stock market fell precipitously in a matter of minutes, wiping out trillions of dollars of investments, and then recovered within minutes. Use the Internet to investigate the causes of this crash and discuss the issues it raises.

(3,1)arrow_forwardProblem description: In a car security system, we usually want to connect the siren in such a way that the siren will activate when it is triggered by one or more sensors. In addition, there will be a master switch to turn the system on or off. Let us assume that there is a car door switch D, a vibration detector switch V, and the master switch M. We will use the convention that when the door is opened D = 1, otherwise, D = 0. Similarly, when the car is being shaken, V = 1, otherwise, V = 0. Thus, we want the siren S to turn on, that is, set S = 1, when either D = 1 or V = 1, or when both D = 1and V = 1, but only for when the system is turned on, that is when M = 1. However, when we turn off the system, and either enter or drive the car, we do not want the siren to turn on. Hence, when M = 0, it does not matter what values D and V have, the siren should remain off. Instruction: Start by constructing a truth table, which is basically a precise way of stating the operations for the…arrow_forwardFor each of the following statements, state whether it is True or False.arrow_forward
- use python When a share of common stock of some company is sold, the capital gain (or, sometimes, loss) is the difference between the share’s selling price and the price originally paid to buy it. This rule is easy to understand for a single share, but if we sell multiple shares of stock bought over a long period of time, then we must identify the shares actually being sold. A standard accounting principle for identifying which shares of a stock were sold in such a case is to use a FIFO protocol—the shares sold are the ones that have been held the longest (indeed, this is the default method built into several personal finance software packages). For example, suppose we: buy 100 shares at $20 each, buy 20 shares at $24 each, buy 200 shares at $36 each, sell 150 shares at $30 each, in this order. Then applying the FIFO protocol means that of the 150 shares sold, 100 were bought on day 1, 20 were bought on day 2, and 30 were bought on day 3. The capital gain in this case would…arrow_forward-Fill in the definitions below and provide examples for each: Logic error: An example of a pseudocode logic error would be (explain why):arrow_forwardF(w, x, y, z) = ∑(1, 3, 4, 5, 10, 11, 12, 13, 14, 15) List of prime implicantarrow_forward
- State whether the following statements are true or false and justify your answersarrow_forwardProblem #2: [35 pts] Parity Bit CheckerThe parity bit of a sequence of bits is 0 if the number of 1’s in the sequence is even and 1otherwise.Example: if the sequence of bits is 1 1 0 1, the parity bit should be 1 (total number of 1-bits is 3 whichis odd) if the sequence of bits is 1 0 1 0, the parity bit should be 0 (total number of 1-bits is 2 whichis even)Write a Java program that asks the user to enter the number of bits he has. The program thenreads the bits as separate integers. In the end, the program prints the parity bit on the screen. Ifthe use enters a bit value that is neither 0 nor 1, the entry should be discarded and a messagedisplayed as shown in the sample run.Sample run 1:How many bits do you have? 6Enter 6 bits: 1 1 0 0 1 0The parity bit is 1Sample run 2:How many bits do you have? 8Enter 8 bits: 1 1 1 0 0 0 0 1The parity bit is 0Sample run 3:How many bits do you have? 5Enter 5 bits: 1 1 3 0 1Incorrect bit value 3 is discarded.The parity bit is 1 java brogramarrow_forwardProblem 1 (#2.1.8).
