Answer:
Referential key is the correct answer to the given question .
Explanation:
The Referential key is also known as foreign key .In the Referential key the foreign key table field must be match with the field of primary key table in another table .
The main objective of Referential key providing the interaction between the two tables also the Referential key is provides the concept of referential integrity .
Primary key is used find the unique record in the database they are not created when the two tables contain the common field so that's why it is incorrect option.Key template and Relationship are not providing the linking between the two tables that's why it is incorrect option .4.

The Monte Carlo (MC) Method (Monte Carlo Simulation) was first published in 1949 by Nicholas Metropolis and Stanislaw Ulam in the work "The Monte Carlo Method" in the Journal of American Statistics Association. The name Monte Carlo has its origins in the fact that Ulam had an uncle who regularly gambled at the Monte Carlo casino in Monaco. In fact, way before 1949 the method had already been extensively used as a secret project of the U.S. Defense Department during the so-called "Manhattan Project". The basic principle of the Monte Carlo Method is to implement on a computer the Strong Law of Large Numbers (SLLN) (see also Lecture 9). The Monte Carlo Method is also typically used as a probabilistic method to numerically compute an approximation of a quantity that is very hard or even impossible to compute exactly like, e.g., integrals (in particular, integrals in very high dimensions!). The goal of Problem 2 is to write a Python code to estimate the irrational number
Answer:
can you give more detail
Explanation:
A company that wants to send data over the Internet has asked you to write a program that will encrypt it so that it may be transmitted more securely. All the data is transmitted as four-digit integers. Your app should read a four-digit integer entered by the user and encrypt it as follows: Replace each digit with the result of adding 7 to the digit and getting the remainder after dividing the new value by 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then display the encrypted integer. Write a separate app that inputs an encrypted four-digit integer and decrypts it (by reversing the encryption scheme) to form the original number. Use the format specifier D4 to display the encrypted value in case the number starts with a 0
Answer:
The output of the code:
Enter a 4 digit integer : 1 2 3 4
The decrypted number is : 0 1 8 9
The original number is : 1 2 3 4
Explanation:
Okay, the code will be written in Java(programming language) and the file must be saved as "Encryption.java."
Here is the code, you can just copy and paste the code;
import java.util.Scanner;
public class Encryption {
public static String encrypt(String number) {
int arr[] = new int[4];
for(int i=0;i<4;i++) {
char ch = number.charAt(i);
arr[i] = Character.getNumericValue(ch);
}
for(int i=0;i<4;i++) {
int temp = arr[i] ;
temp += 7 ;
temp = temp % 10 ;
arr[i] = temp ;
}
int temp = arr[0];
arr[0] = arr[2];
arr[2]= temp ;
temp = arr[1];
arr[1] =arr[3];
arr[3] = temp ;
int newNumber = 0 ;
for(int i=0;i<4;i++)
newNumber = newNumber * 10 + arr[i];
String output = Integer.toString(newNumber);
if(arr[0]==0)
output = "0"+output;
return output;
}

An organization’s SOC analyst, through examination of the company’s SIEM, discovers what she believes is Chinese-state sponsored espionage activity on the company’s network. Management agrees with her initial findings given the forensic artifacts she presents are characteristics of malware, but management is unclear on why the analyst thought it was Chinese-state sponsored. You have been brought in as a consultant to help determine 1) whether the systems have been compromised and 2) whether the analyst’s assertion has valid grounds to believe it is Chinese state-sponsored. What steps would you take to answer these questions given that you have been provided a MD5 hashes, two call back domains, and an email that is believed to have been used to conduct a spearphishing attack associated with the corresponding MD5 hash. What other threat intelligence can be generated from this information and how would that help shape your assessment?
Answer: Provided in the explanation segment
Explanation:
Below is a detailed explanation to make this problem more clearer to understand.
(1). We are asked to determine whether the systems have been compromised;
Ans: (YES) From the question given, We can see that the System is compromised. This is so because the plan of communication has different details of scenarios where incidents occur. This communication plan has a well read table of contents that lists specific type of incidents, where each incident has a brief description of the event.
(2). Whether the analyst’s assertion has valid grounds to believe it is Chinese state-sponsored.
Ans: I can say that the analyst uses several different internet protocol address located in so as to conduct its operations, in one instance, a log file recovered form an open indexed server revealed tham an IP address located is used to administer the command control node that was communicating with the malware.
(3). What other threat intelligence can be generated from this information?
Ans: The threat that can be generated from this include; Custom backdoors, Strategic web compromises, and also Web Server exploitation.
(4). How would that help shape your assessment?
Ans: This helps in such a way where information is gathered and transferred out of the target network which involve movement of files through multiple systems.
Files also gotten from networks as well as using tools (archival) to compress and also encrypt data with effectiveness of their data theft.
cheers i hope this helped!!!
Dave owns a construction business and is in the process of buying a laptop. He is looking for a laptop with a hard drive that will likely continue to function if the computer is dropped. Which type of hard drive does he need?
Answer:
Solid state drive
Explanation:
The term solid-state drive is used for the electronic circuitry made entirely from semiconductors. This highlights the fact that the main storage form, in terms of a solid-state drive, is via semiconductors instead of a magnetic media for example a hard disk. In lieu of a more conventional hard drive, SSD is built to live inside the device. SSDs are usually more resistant to physical shock in comparison to the electro-mechanical drives and it functions quietly and has faster response time. Therefore, SSD will be best suitable for the Dave.

Describe the series of connections that would be made, equipment and protocol changes, if you connected your laptop to a wireless hotspot and opened your email program and sent an email to someone. Think of all the layers and the round trip the information will likely make.
Answer:
Check Explanation.
Explanation:
Immediately there is a connection between your laptop and the wireless hotspot, data will be transferred via the Physical layer that will be used for encoding of the network and the modulation of the network and that layer is called the OSI MODEL.
Another Important layer is the APPLICATION LAYER in which its main aim and objectives is for support that is to say it is used in software supporting.
The next layer is the PRESENTATION LAYER which is used during the process of sending the e-mail. This layer is a very important layer because it helps to back up your data and it is also been used to make connections of sessions between servers of different computers
To encrypt messages I propose the formula C = (3P + 1) mod 27, where P is the "plain text" (the original letter value) and C is the "cipher text" (the encrypted letter value). For example, if P = 2 (the letter 'c' ), C would be 7 (the letter 'h') since (3(2) + 1) mod 27 = 7. There is a problem though: When I send the message 'c' to my friend, encrypted as 'h', they don't know whether the original message was 'c' or another letter that also encrypts to 'h'. What other letter(s) would also encrypt to 'h' besides 'c' in this system?
Answer:
C = (3P+1) % 27
so when P will be max 26,when P is 26 the (3P+1) = 79. And 79/27 = 2 so let's give name n = 2.
Now doing reverse process
We get ,
P = ((27*n)+C-1)/3
Where n can be 0,1,2
So substituting value of n one by one and the C=7(corresponding index of h)
For n= 0,we get P=2, corresponding char is 'c'
For n=1,we get P=11, corresponding char is 'l'
For n=2,we get P= 20, corresponding cahr is 'u'.
So beside 'c',the system will generate 'h' for 'l' and 'u' also.
Suppose that a program's data and executable code require 1,024 bytes of memory. A new section of code must be added; it will be used with various values 70 times during the execution of a program. When implemented as a macro, the macro code requires 73 bytes of memory. When implemented as a procedure, the procedure code requires 132 bytes (including parameter-passing, etc.), and each procedure call requires 7 bytes. How many bytes of memory will the entire program require if the new code is added as a procedure? 1,646
Answer:
The answer is 1646
Explanation:
The original code requires 1024 bytes and is called 70 times ,it requires 7 byte and its size is 132 bytes
1024 + (70*7) + 132 = 1024 + 490 +132
= 1646
For this problem, you will write a function standard_deviation that takes a list whose elements are numbers (they may be floats or ints), and returns their standard deviation, a single number. You may call the variance method defined above (which makes this problem easy), and you may use sqrt from the math library, which we have already imported for you. Passing an empty list to standard_deviation should result in a ZeroDivisionError exception being raised, although you should not have to explicitly raise it yourself.
Answer:
import math def standard_deviation(aList): sum = 0 for x in aList: sum += x mean = sum / float(len(aList)) sumDe = 0 for x in aList: sumDe += (x - mean) * (x - mean) variance = sumDe / float(len(aList)) SD = math.sqrt(variance) return SD print(standard_deviation([3,6, 7, 9, 12, 17]))Explanation:
The solution code is written in Python 3.
Firstly, we need to import math module (Line 1).
Next, create a function standard_deviation that takes one input parameter, which is a list (Line 3). In the function, calculate the mean for the value in the input list (Line 4-8). Next, use the mean to calculate the variance (Line 10-15). Next, use sqrt method from math module to get the square root of variance and this will result in standard deviation (Line 16). At last, return the standard deviation (Line 18).
We can test the function using a sample list (Line 20) and we shall get 4.509249752822894
If we pass an empty list, a ZeroDivisionError exception will be raised.

Explanation:
Base on the scenario been described in the question, We are 95% confident that the price of a single hard drive with 33 megahertz speed and 386 CPU falls between $3,943 and $4,987
customer seeks to buy a new computer for private use at home. The customer primarily needs the computer to use the Microsoft PowerPoint application for the purpose of practicing presentation skills. As a salesperson what size hard disc would you recommend and why?
Explanation:
The most reliable hard drives are those whose most common size is 3.5 inches, their advantages are their storage capacity and their speed and a disadvantage is that they usually make more noise.
For greater speed, it is ideal to opt for two smaller hard disks, since large disks are slower, but are partitioned so that there are no problems with file loss.
For a person who needs to use content creation programs, it is ideal to opt for a hard drive that has reliability.
Components of a product or system must be
1) Reliable
2) Flexible
3) Purposeful
4)Interchangeable
Answer:
The correct answer to the following question will be Option D (Interchangeable).
Explanation:
Interchangeability applies towards any portion, part as well as a unit that could be accompanied either by equivalent portion, component, and unit within a specified commodity or piece of technology or equipment.This would be the degree to which another object can be quickly replaced with such an equivalent object without re-calibration being required.The other three solutions are not situation-ally appropriate, so option D seems to be the right choice.
6. Why did he choose to install the window not totally plumb?
Answer:
Because then it would break
Explanation:
You achieve this by obtaining correct measurements. When measuring a window, plumb refers to the vertical planes, and level refers to the horizontal planes. So he did not install the window totally plumb

Let U = {b1, b2, , bn} with n ≥ 3. Interpret the following algorithm in the context of urn problems. for i is in {1, 2, , n} do for j is in {i + 1, i + 2, , n} do for k is in {j + 1, j + 2, ..., n} do print bi, bj, bk How many lines does it print? It prints all the possible ways to draw three balls in sequence, without replacement. It prints P(n, 3) lines. It prints all the possible ways to draw an unordered set of three balls, without replacement. It prints P(n, 3) lines. It prints all the possible ways to draw three balls in sequence, with replacement. It prints P(n, 3) lines. It prints all the possible ways to draw an unordered set of three balls, without replacement. It prints C(n, 3) lines. It prints all the possible ways to draw three balls in sequence, with replacement. It prints C(n, 3) lines.
Answer:
Check the explanation
Explanation:
Kindly check the attached image for the first step
Note that the -print" statement executes n(n — I)(n — 2) times and the index values for i, j, and k can never be the same.
Therefore, the algorithm prints out all the possible ways to draw three balls in sequence, without replacement.
Now we need to determine the number of lines this the algorithm print. In this case, we are selecting three different balls randomly from a set of n balls. So, this involves permutation.
Therefore, the algorithm prints the total
P(n, 3)
lines.

*Sometimes it is difficult to convince top management to commit funds to develop and implement a SIS why*
Step-by-step Explanation:
SIS stands for: The Student Information System (SIS).
This system (a secure, web-based accessible by students, parents and staff) supports all aspects of a student’s educational experience, and other information. Examples are academic programs, test grades, health information, scheduling, etc.
It is difficult to convince top management to commit funds to develop and implement SIS, this can be due to a thousand reasons.
The obvious is that the management don't see the need for it. They would rather have students go through the educational process the same way they did. Perhaps, they just don't trust the whole process, they feel more in-charge while using a manual process.
Trace the complete execution of the MergeSort algorithm when called on the array of integers, numbers, below. Show the resulting sub-arrays formed after each call to merge by enclosing them in { }. For example, if you originally had an array of 5 elements, a = {5,2,8,3,7}, the first call to merge would result with: {2, 5} 8, 3, 7 ← Note after the first call to merge, two arrays of size 1 have been merged into the sorted subarray {2,5} and the values 2 and 5 are sorted in array a You are to do this trace for the array, numbers, below. Be sure to show the resulting sub-arrays after each call to MergeSort. int[] numbers = {23, 14, 3, 56, 17, 8, 42, 18, 5};

Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of 32-bits memory address references given as word addresses. 0x03, 0xb4, 0x2b, 0x02, 0xbf, 0x58, 0xbe, 0x0e, 0xb5, 0x2c, 0xba, 0xfd For each of these references identify the binary word address, the tag, and the index given a direct mapped cache with 16 one-word blocks. Also list whether each reference is a hit or a miss, assuming the cache is initially empty.
