When implementing a 1:1 relationship, where should you place the foreign key if one side is mandatory and one side is optional? Should the foreign key be mandatory or optional?
Answer:
When implementing a 1:1 relationship, the foreign key should be placed on the optional side if one side is mandatory and one side is optional.
When this is implemented, the foreign key should be made mandatory.
Explanation:
A foreign key (FK) is a primary key (PK) in relational databases. It is used to establish a relationship with a table that has the same attribute with another table in the database. A mandatory relationship exists when the foreign key depends on the parent (primary key) and cannot exist without the parent. A one-to-one relationship exists when one row in a data table may be linked with only one row in another data table.
provides an automated method for discovering host systems on a network. Although it doesn't necessarily discover all weaknesses, it does determine which systems are active on the network and what services they offer or what ports are available
Answer:
Network scan
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.
Generally, a security assessment is carried out by network security experts on a regular basis to determine potential loopholes or vulnerabilities in the information and technology (IT) infrastructure. One of the techniques or approach used in security assessment is a network scan.
A network scan is a security assessment technique used for the automatic detection of host systems on a network. Although a network scan isn't capable of discovering or detecting all the weaknesses on a network, it avails users information about the computer systems that are active on the network and what services the computer systems offer or what ports are available on them.

Write a program named edit_data.py that asks a person their age. Accept an int. Use a custom exception to return a message if the number entered is an int that is less than 1 or greater than 115. Create an exception that catches an error if a non int is entered.
An error that occurs while a program is being run is an exception. Non-programmers see exceptions as examples that do not follow a general rule.
What is the programming?
In computer science, the term "exception" also has the following connotation: It signifies that the issue is an uncommon occurrence; it is the "exception to the rule." Some programming languages use the mechanism known as exception handling to deal with problems automatically. Exception handling is built into several programming languages, including C++, Objective-C, PHP, Java, Ruby, Python, and many others.
In order to manage errors, programs often save the state of execution at the time the problem occurred and interrupt their usual operation to run an exception handler, which is a particular function or section of code. Depending on the type of error that had occurred, the error handler can "correct" the issue and the application can then continue using the previously saved data.
Thus, An error that occurs while a program is being run is an exception.

Which operating system desktop or mobile is the best
Answer:
bing or alien ware is the best.
Answer:
Your choice, but personally, desktop is better.
Explanation:
Desktop devices have portrait orientations so content can stretch across a screen and often multiple messages or images can live comfortably in such a wide space. Mobile devices are usually used in portrait orientation (and the smaller screens mean that even in landscape mode, horizontal space is limited).

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

/*
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.

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);
}

The valid call to the function installApplication is
void main( )
{
// call the function installApplication
}
void installApplication(char appInitial, int appVersion)
{
// rest of function not important
}
Answer:
B. installApplication(‘A’, 1);
Explanation:
Given
The above code segment
Required
The correct call to installApplication
The function installApplication is declared as void, meaning that it is not expected to return anything.
Also, it receives a character and an integer argument.
So, the call to this function must include a character and an integer argument, in that order.
Option D is incorrect because both arguments are integer
Option C is incorrect because it passes no argument to the function.
Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).
Option B is correct
Suppose during a TCP connection between A and B, B acting as a TCP receiver, sometimes discards segments received out of sequence, but sometimes buffers them. Would the data sent by A still be delivered reliably and in-sequence at B? Explain why.
Answer:
Yes
Explanation:
We known that TCP is the connection [tex]\text{oriented}[/tex] protocol. So the TCP expects for the target host to acknowledge or to check that the [tex]\text{communication}[/tex] session has been established or not.
Also the End stations that is running reliable protocols will be working together in order to verify transmission of data so as to ensure the accuracy and the integrity of the data. Hence it is reliable and so the data can be sent A will still be delivered reliably and it is in-sequence at B.

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
hence C = 1
given that: carry in = carry out there will be zero ( 0 ) overflow
hence V = 0
also Z = 1
But the most significant bit is N = 1

Can anyone decipher these? There a bit random. Maybe binary but if there are other ways please include them.
Answer:
Explanation:
so this is what "format" is about, it's saying what do the ones and zeros represent. b/c the bits can represent lots of different things , like letters with ascii code , and that's got several types. some are 8 bits, some are 16 bits, the questions you've shown are in groups of 5 which is really not a "thing" in binary, it's always by twos, without some type of "frame work" around the bits, we won't know what they represent, if that is helping? the important part is what is the "frame work" that these bits are in.
all of your questions seem to have some "art" thing going on, they make some kinda of binary artwork, for what they are saying, that's not what's important. Other than if they form palindromes, maybe that's what the questions are really about, how these do from palindromes, that is, they read the same backwards as forwards... I know.. why would anyone read backwards.. but a computer can do that pretty quickly, sooo sometimes to check, it will read forwards and backwards.. but when there is a palindrome, the computer is "confused"
this is also a big big part of "typing" not like on a keyboard but when you program, and you say that your variables are of a certain type, like a char, or a string, or a double, you are specifying how many bits will be used to represent your data. so then when you put the ones and zeros into the memory , ( think RAM) then it's stored in groups of what ever size you've determined. hmmmm does this help?

Open the file data.txt and obtain the file handler fh;
Create a thread my_thread using pthread_create; pass fh to my_thread;
Wait until my_thread terminates, using pthread_join;
Print out how many lines exist in data.txt.}
Basic structure of thread_function.c:
void *count_lines(void *arg)
{
Obtain fh from arg;
Count how many lines num_lines exist in fh;
Close fh;
Return num_lines
}
Answer:
Here is the code:-
//include the required header files
#include<stdio.h>
#include<pthread.h>
// method protocol definition
void *count_lines(void *arg);
int main()
{
// Create a thread handler
pthread_t my_thread;
// Create a file handler
FILE *fh;
// declare the variable
int *linecnt;
// open the data file
fh=fopen("data.txt","r");
// Create a thread using pthread_create; pass fh to my_thread;
pthread_create(&my_thread, NULL, count_lines, (void*)fh);
//Use pthread_join to terminate the thread my_thread
pthread_join( my_thread, (void**)&linecnt );
// print the number of lines
printf("\nNumber of lines in the given file: %d \n\n", linecnt);
return (0);
}
// Method to count the number of lines
void *count_lines(void *arg)
{
// variable declaration and initialization
int linecnt=-1;
char TTline[1600];
//code to count the number of lines
while(!feof(arg))
{
fgets(TTline,1600,arg);
linecnt++;
}
pthread_exit((void *)linecnt);
// close the file handler
fclose(arg);
}
Explanation:
Program:-
LAB: Count multiples (EO)
Complete a program that creates an object of the Count class, takes three integers as input: low, high, and x, and then calls the countMultiples() method. The countMultiples() method then returns the number of multiples of x between low and high inclusively.
Ex: If the input is:
1 10 2
countMutiples() returns and the program output is:
5
Hint: Use the % operator to determine if a number is a multiple of x. Use a for loop to test each number between low and high.
Note: Your program must define the method:
public int countMultiples(int low, int high, int x)
Count.java
1 import java.util.Scanner;
2
3 public class Count {
4
5 public int countMultiples(int low, int high, int x) {
6 /* Type your code here. */
7
8 }
9
10 public static void main(String[] args) {
11 Scanner scnr = new Scanner(System.in);
12 /* Type your code here. */
13 }
14)
15
Following are the Java Program to the given question:
import java.util.Scanner; //import package for user-input
public class Count //defining a class Count
{
public static int countMultiples(int low,int high,int x)//defining a method countMultiples that takes three integer parameters
{
int c=0,i; //defining integer variables that hold value
for(i=low;i<=high;i++)//defining loop that iterates value between low and high
{
if(i%x==0)//defining if block that uses % operator to check value
{
c+=1; //incrementing c value
}
}
return c; //return c value
}
public static void main(String[] args)//main method
{
int l,h,x;//defining integer variable
Scanner scnr=new Scanner(System.in); //creating scanner class object
l=scnr.nextInt(); //input value
h=scnr.nextInt();//input value
x=scnr.nextInt();//input value
System.out.println(countMultiples(l,h,x)); //calling method and print its value
}
}
Output:
Please find the attached file.
Program Explanation:
Import package.Defining a class "Count", and inside the class two method "countMultiples and main method" is declared.In the "countMultiples" method three integer parameter that are "low, high, and x".Inside this method a for loop is declared that uses the parameter value and use conditional statement with the % operator and check and return its values.Inside the main method three integer variable is declared that uses the scanner class to input the value and pass to the method and print its calculated value.Learn more:

Explanation:
Write a program that reads in the size of the side of a square and then prints a hollow square of that size out of asterisks and
blanks. Your program should work for squares of all side sizes between 1 and 20. For example, if your program reads a size of 5, it
should print
Answer:
Explanation:
#include <iostream>
using std::cout;
using std::endl;
using std::cin;
int main()
{
int side, rowPosition, size;
cout << "Enter the square side: ";
cin >> side;
size = side;
while ( side > 0 ) {
rowPosition = size;
while ( rowPosition > 0 ) {
if ( size == side || side == 1 || rowPosition == 1 ||
rowPosition == size )
cout << '*';
else
cout << ' ';
--rowPosition;
}
cout << '\n';
--side;
}
cout << endl;
return 0;
}
