Which of the following restricts the ability for individuals to reveal information present in some part of the database?
a. Access Control
b. Inference Control
c. Flow Control
d. Encyption
Answer:
it would have to be flow control which would be C.
Explanation:
Flow Control is restricts the ability for individuals to reveal information present in some part of the database. Hence, option C is correct.
What is Flow Control?The management of data flow between computers, devices, or network nodes is known as flow control. This allows the data to be processed at an effective rate. Data overflow, which occurs when a device receives too much data before it can handle it, results in data loss or retransmission.
A design concern at the data link layer is flow control. It is a method that typically monitors the correct data flow from sender to recipient. It is very important because it allows the transmitter to convey data or information at a very quick rate, which allows the receiver to receive it and process it.
The amount of data transmitted to the receiver side without any acknowledgement is dealt with by flow control.
Thus, option C is correct.

Add (total) all the number in the list (below) using a for loop, but skip over the number at index 3.
numbers = [10,20,30,40,50,60,100]
Answer:
The program in Python is as follows:
numbers = [10,20,30,40,50,60,100]
total = 0
for i in range(len(numbers)):
if i != 3:
total+=numbers[i]
print(total)
Explanation:
This initializes the list
numbers = [10,20,30,40,50,60,100]
Set total to 0
total = 0
This iterates through numbers
for i in range(len(numbers)):
This ensures that the index 3, are not added
if i != 3:
total+=numbers[i]
Print the calculated sum
print(total)
Fill in multiple blanks for [x], [y], [z]. Consider a given TCP connection between host A and host B. Host B has received all from A all bytes up to and including byte number 2000. Suppose host A then sends three segments to host B back-to-back. The first, second and third segments contain 50, 600 and 100 bytes of user data respectively. In the first segment, the sequence number is 2001, the source port number is 80, and the destination port number is 12000. If the first segment, then third segment, then second segment arrive at host B in that order, consider the acknowledgment sent by B in response to receiving the third segment. What is the acknowledgement number [x], source port number [y] and destination port number [z] of that acknowledgement
Should you remove jewelry, pens, and other metal objects before entering the magnetic resonance (MR) environment even if the equipment is not in use?
Answer:
Yes you should
Explanation:
When you are about to enter the mr the best thing you should do is to take off any form of metallic objects that you may have on you this could be a wrist watch, it could be other forms of accessories such as hair clips, keys or even coins. having any of these objects on you could cause a person to have an injury.
This is because this object could change its position when in the room also it could cause signal losses and could also make objects unclear for the radiologist

3. Circular, array-backed queue In the following class, which you are to complete, the backing array will be created and populated with Nones in the __init__ method, and the head and tail indexes set to sentinel values (you shouldn't need to modify __init__). Enqueuing and Dequeuing items will take place at the tail and head, with tail and head tracking the position of the most recently enqueued item and that of the next item to dequeue, respectively. To simplify testing, your implementation should make sure that when dequeuing an item its slot in the array is reset to None, and when the queue is emptied its head and tail attributes should be set to -1.

Answer:
All flags are On ( c, z , N )
Explanation:
Given data:
4-bit operation
Assuming 2's complement representation
Determine status flags that are on after performing 1010+0110
1 1
1 0 1 0
0 1 1 0
1 0 0 0 0
we will carry bit = 1 over

Number of strings: 6
Number of frets: 19
Answer:
Explanation:
Using the main() and Instrument class which can be found online. We can create the following StringInstrument class that extends the Instrument class itself. The only seperate variables that the StringInstrument class posses' would be the number of Strings (numStrings) and the number of frets (numFrets). Due to technical difficulties I have added the code as a seperate text file below.
A recursive method may call other methods, including calling itself. Creating a recursive method can be accomplished in two steps. 1. Write the base case -- Every recursive method must have a case that returns a value or exits from the method without performing a recursive call. That case is called the base case. A programmer may write that part of the method first, and then lest. There may be multiple base cases.Complete the recursive method that returns the exponent of a given number. For e.g. given the number 5 and the exponent 3 (53) the method returns 125. Note: any number to the zero power is 1. Note: Do not code for the example. Your method must work for all given parameters! Use this as your method header: public static int raiseToPower(int base, int exponent)
Answer:
Explanation:
The following code is written in Java. It creates the raiseToPower method that takes in two int parameters. It then uses recursion to calculate the value of the first parameter raised to the power of the second parameter. Three test cases have been provided in the main method of the program and the output can be seen in the attached image below.
class Brainly {
public static void main(String[] args) {
System.out.println("Base 5, Exponent 3: " + raiseToPower(5,3));
System.out.println("Base 2, Exponent 7: " + raiseToPower(2,7));
System.out.println("Base 5, Exponent 9: " + raiseToPower(5,9));
}
public static int raiseToPower(int base, int exponent) {
if (exponent == 0) {
return 1;
} else if (exponent == 1) {
return base;
} else {
return (base * raiseToPower(base, exponent-1));
}
}

In confirmatory visualization Group of answer choices Users expect to see a certain pattern in the data Users confirm the quality of data visualization Users don't know what they are looking for Users typically look for anomaly in the data
Answer: Users expect to see a certain pattern in the data
Explanation:
Confirmatory Data Analysis occurs when the evidence is being evaluated through the use of traditional statistical tools like confidence, significance, and inference.
In this case, there's an hypothesis and the aim is to determine if the hypothesis is true. In this case, we want to know if a particular pattern on the data visualization conforms to what we have.
Print the two strings in alphabetical order. Assume the strings are lowercase. End with newline. Sample output: capes rabbits import java.util.Scanner: public class OrderStrings { public static void main (String args) { String firstString: String secondString: firstString = "rabbits" secondString = "capes" /*Your solution goes here */ return: } }import java.util.Scanner;public class OrderStrings { public static void main(String[] args) { String firstString; String secondString; firstString = "rabbit"; secondString= "capes"; //String class in java provide string comparison function, use it, and get //your work done may even use brute force i.e using for loop and compare character by // character which will not good for the programming language which already have vast //predefined number of functions if(firstString.compareTo(secondString) < 0){ System.out.println(firstString + " " + secondString); } else{ System.out.println(secondString + " " + firstString); } return; }}
Answer:
Following are the code to the given question:
import java.util.Scanner;//import package
public class OrderStrings // defining a class OrderStrings
{
public static void main(String[] args) //defining a main method
{
Scanner scnr = new Scanner(System.in);//defining a Scanner class object
String firstString;//defining a String variable
String secondString; //defining a String variable
firstString = scnr.next();//input value
secondString = scnr.next();//input value
if (firstString.compareTo(secondString) < 0)//use if to compare sting value
System.out.println(firstString + " " + secondString);//print sting value
else//else block
System.out.println(secondString + " " + firstString);//print sting value
}
}
Output:
rabbits capes
capes rabbits
Explanation:
In this code a class "OrderStrings" is defined inside the class the main method is defined that declares the two string variable that uses the input method to input the string value and after input, it uses the conditional statement. Inside this compareTo method is declared that compare string value and prints the string value.
In this era of technology, everyone uses emails for mail and messages. Assume you have also used the
mailboxes for conversation. Model the object classes that might be used in Email system implementation
to represent a mailbox and an email message.
Assume You are working as a software engineer and now you have been asked to deliver a presentation to
a manager to justify the hiring of a system architect for a new project. Write a list of bullet points setting
out the key points in your presentation in which you explain the importance of software architecture
Answer:
A class may be a structured diagram that describes the structure of the system.
It consists of sophistication name, attributes, methods, and responsibilities.
A mailbox and an email message have certain attributes like, compose, reply, draft, inbox, etc.
Software architecture affects:
Performance, Robustness, Distributability, Maintainability.
Explanation:
See attachment for the Model object classes which may be utilized in the system implementation to represent a mailbox and an email message.
Advantages:
Large-scale reuse Software architecture is vital because it affects the performance, robustness, distributability, and maintainability of a system.
Individual components implement the functional system requirements, but the dominant influence on the non-functional system characteristics is that the system's architecture.
Three advantages of System architecture:
• Stakeholder communication: The architecture may be a high-level presentation of the system which will be used as attention for discussion by a variety of various stakeholders.
• System analysis: making the system architecture explicit at an early stage within the system development requires some analysis.
• Large-scale reuse:
An architectural model may be a compact, manageable description of how a system is organized and the way the components interoperate.
The system architecture is usually an equivalent for systems with similar requirements then can support large-scale software reuse..

Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b, 4) should return 0.
Answer:
The function in C++ is as follows:
int isSorted(int ar[], int n){
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
return isSorted(ar, n - 1);}
Explanation:
This defines the function
int isSorted(int ar[], int n){
This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
This checks if the current element is less than the previous array element; If yes, the array is not sorted
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
This calls the function, recursively
return isSorted(ar, n - 1);
}
Write a statement that assigns numCoins with numNickels + numDimes. Ex: 5 nickels and 6 dimes results in 11 coins. Note: These activities may test code with different test values. This activity will perform two tests: the first with nickels = 5 and dimes = 6, the second with nickels = 9 and dimes = 0.
1 import java.util.Scanner;

3 public class AssigningSum {
4 public static void main(String[] args) {
5 int numCoins;
6 int numNickels;
7 int numDimes;
8
9 numNickels = 5;
10 numDimes - 6;
11
12 /* Your solution goes here
13
14 System.out.print("There are ");
15 System.out.print(numCoins);
16 System.out.println(" coins");
17 }
18 }
Answer:
Explanation:
The statement solution was added to the code and then the code was repeated in order to create the second test case with 9 nickels and 0 dimes. The outputs for both test cases can be seen in the attached image below.
import java.util.Scanner;
class AssigningSum {
public static void main(String[] args) {
int numCoins;
int numNickels;
int numDimes;
numNickels = 5;
numDimes = 6;
/* Your solution goes here */
numCoins = numNickels + numDimes;
System.out.print("There are ");
System.out.print(numCoins);
System.out.println(" coins");
// TEST CASE 2
numNickels = 9;
numDimes = 0;
/* Your solution goes here */
numCoins = numNickels + numDimes;
System.out.print("There are ");
System.out.print(numCoins);
System.out.println(" coins");
}

Try to test those codes and modify as you wish for getting more clarification.In additiontry the following:---------------------------------------------------------------------------------------------------------------------------------------1.What would be the output of the following recursive function if we call rec2(5)
Answer:
The output is:
1 2 3 4 5
Explanation:
Given
See attachment for code segment
Required
The output of rec2(5)
From the attached code segment, we have the following:
The base case: if (x==0){ return;}
The above implies that, the recursion ends when the value of x gets reduced to 0
The recursion:
rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function
printf("%d ", x); This prints the passed value of x
Hence, the output of rec2(5) is: 1 2 3 4 5

Answer:
Explanation:
/* From the information provided, For now will consider the name of table as TRIPGUIDES*/
/*In all the answers below, the syntax is based on Oracle SQL. In case of usage of other database queries, answer may vary to some extent*/
1.
Select R.Reservation_ID, R.Trip_ID , C.Customer_Num,C.Last_Name from Reservation R, Customer C where C.Customer_Num=R.Customer_Num ORDER BY C.Last_Name
/*idea is to select the join the two tables by comparing customer_id field in two tables as it is the only field which is common and then print the desired result later ordering by last name to get the results in sorted order*/
2.
Select R.Reservation_ID, R.Trip_ID , R.NUM_PERSONS from Reservation R, Customer C where C.Customer_Num=R.Customer_Num and C.LAST_NAME='Goff' and C.FIRST_NAME='Ryan'
/*Here, the explaination will be similar to the first query. Choose the desired columns from the tables, and join the two tables by equating the common field
*/
3.
Select T.TRIP_NAME from TRIP T,GUIDE G,TRIPGUIDES TG where T.TRIP_ID=TG.TRIP_ID and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Abrams' and G.FIRST_NAME='Miles'
/*
Here,we choose three tables TRIP,GUIDE and TRIPGUIDES. Here we selected those trips where we have guides as Miles Abrms in the GUIDES table and equated Trip_id from TRIPGUIDES to TRIP.TRIP_Name so that can have the desired results
*/
4.
Select T.TRIP_NAME
from TRIP T,TRIPGUIDES TG ,G.GUIDE
where T.TRIP_ID=TG.TRIP_ID and T.TYPE='Biking' and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Boyers' and G.FIRST_NAME='Rita'
/*
In the above question, we first selected the trip name from trip table. To put the condition we first make sure that all the three tables are connected properly. In order to do so, we have equated Guide_nums in guide and tripguides. and also equated trip_id in tripguides and trip. Then we equated names from guide tables and type from trip table for the desired results.
*/
5.
SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='2016-07-23' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM
/*
The explaination for this one will be equivalent to the previous question where we just equated the desired columns where we equiated the desired columns in respective fields and also equated the common entities like trip ids and customer ids so that can join tables properly
*/
/*The comparison of dates in SQL depends on the format in which they are stored. In the upper case if the
dates are stored in the format as YYYY-MM-DD, then the above query mentioned will work. In case dates are stored in the form of a string then the following query will work.
SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='7/23/2016' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM
*/
6.
Select R.RESERVATION_ID, R.TRIP_ID,R.TRIP_DATE FROM RESERVATION R WHERE R.TRIP_ID IN
{SELECT TRIP_ID FROM TRIP T WHERE STATE='ME'}
/*
In the above question, we firstly extracted all the trip id's which are having locations as maine. Now we have the list of all the trip_id's that have location maine. Now we just need to extract the reservation ids for the same which can be trivally done by simply using the in clause stating print all the tuples whose id's are there in the list of inner query. Remember, IN always checks in the set of values.
*/
7.
Select R.RESERVATION_ID, R.TRIP_ID,R.TRIP_DATE FROM RESERVATION WHERE
EXISTS {SELECT TRIP_ID FROM TRIP T WHERE STATE='ME' and R.TRIP_ID=T.TRIP_ID}
/*
Unlike IN, Exist returns either true or false based on existance of any tuple in the condition provided. In the question above, firstly we checked for the possibilities if there is a trip in state ME and TRIP_IDs are common. Then we selected reservation ID, trip ID and Trip dates for all queries that returns true for inner query
*/
8.
SELECT G.LAST_NAME,G.FIRST_NAME FROM GUIDE WHERE G.GUIDE_NUM IN
{
SELECT DISTINCT TG.GUIDE_NUM FROM TRIPGUIDES TG WHERE TG.TRIPID IN {
SELECT T.TRIP_ID FROM TRIP T WHERE T.TYPE='Paddling'
}
}
/*
We have used here double nested IN queries. Firstly we selected all the trips which had paddling type (from the inner most queries). Using the same, we get the list of guides,(basically got the list of guide_numbers) of all the guides eds which were on trips with trip id we got from the inner most queries. Now that we have all the guide_Nums that were on trip with type paddling, we can simply use the query select last name and first name of all the guides which are having guide nums in the list returned by middle query.

If you are going to refer to a few dozen classes in your application, how do
you do it?
Answer:
Explanation:
use the "includes" statement to have access to those classes :)
In C language
In a main function declare an array of 1000 ints. Fill up the array with random numbers that represent the rolls of a die.
That means values from 1 to 6. Write a loop that will count how many times each of the values appears in the array of 1000 die rolls.
Use an array of 6 elements to keep track of the counts, as opposed to 6 individual variables.
Print out how many times each value appears in the array. 1 occurs XXX times 2 occurs XXX times
Hint: If you find yourself repeating the same line of code you need to use a loop. If you declare several variables that are almost the same, maybe you need to use an array. count1, count2, count3, count4, … is wrong. Make an array and use the elements of the array as counters. Output the results using a loop with one printf statement. This gets more important when we are rolling 2 dice.
Answer:
The program in C is as follows:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(){
int dice [1000];
int count [6]={0};
srand(time(0));
for (int i = 0; i < 1000; i++) {
dice[i] = (rand() %(6)) + 1;
count[dice[i]-1]++;
}
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n");
}
return 0;
}
Explanation:
This declares an array that hold each outcome
int dice [1000];
This declares an array that holds the count of each outcome
int count [6]={0};
This lets the program generate different random numbers
srand(time(0));
This loop is repeated 1000 times
for (int i = 0; i < 1000; i++) {
This generates an outcome between 1 and 6 (inclusive)
dice[i] = (rand() %(6)) + 1;
This counts the occurrence of each outcome
count[dice[i]-1]++; }
The following prints the occurrence of each outcome
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n"); }
Preserving confidentiality, integrity, and availability is a restatement of the concern over interruption, interception, modification, and fabrication.
i. Briefly explain the 4 attacks: interruption, interception, modification, and fabrication.
ii. How do the first three security concepts relate to these four attacks
Answer and Explanation:
I and II answered
Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.
Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.
Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.
Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.
If you fail a course as a MAIN (residency) course, you can repeat that course as either a MAIN (residency) or an online (IG or IIG) course. True False
Answer: False
Explanation:
The statement that "you fail a course as a MAIN (residency) course, you can repeat that course as either a MAIN (residency) or an online (IG or IIG) course" is false.
It should be noted that if one fail a course as a residency course, the course can only be repeated as a main (residency) course and not an online course. When a course is failed, such course has to be repeated the following semester and this will give the person the chance to improve their GPA.

(c) 4
Explanation:The function strpos() is a function in php that returns the position of the first occurrence of a particular substring in a string. Positions are counted from 0. The function receives two arguments. The first argument is the string from which the occurrence is to be checked. The second argument is the substring to be checked.
In this case, the string is "Get Well Soon!" while the substring is "Well"
Starting from 0, the substring "Well" can be found to begin at position 4 of the string "Get Well Soon!".
Therefore, the function strpos("Get Well Soon!", "Well") will return 4.
Then, with the echo statement, which is used for printing, value 4 will be printed as output of the code.
