Answer:
D. Each foreign key value MUST match a primary key value in another relation or the foreign key value must be null.
Explanation:
In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.
Basically, there are four (4) types of integrity constraints and these are;
1. Key constraints.
2. Domain constraints.
3. Entity integrity constraints.
4. Referential integrity constraints.
Referential integrity states that each foreign key value must match a primary key value in another relation or the foreign key value must be null.
For instance, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.
Hence, the referential Integrity constraints ensures that the relationship between the data in a table is consistent and valid.

Consider the following code snippet. File hoursFile = new File("hoursWorked.txt"); Your program must read the contents of this file using a Scanner object. Which of the following is the correct syntax for doing this? Scanner in = new Scanner("hoursWorked.txt"); Scanner in = new Scanner(hoursFile); Scanner in = Scanner.open(hoursFile); Scanner in = Scanner("hoursWorked.txt");
Answer:
Scanner in = new Scanner(hoursFile);
Explanation:
The syntax to read the content of a file after the file has been created/initialized is as follows;
Scanner [variable-name] = new Scanner([object-name]);
From the question above, the [object-name] is hoursFile
Substitute [object-name] with hoursFile, the syntax becomes
Scanner [variable-name] = new Scanner(hoursFile);
[variable-name] can be anything as long as it follows variable naming convention;
From the list of given options, the option that answers the question is: Scanner in = new Scanner(hoursFile);

Which of the following is a valid constructor header for the Player class that accepts the player name as a parameter? public void Player(String playerName) private Player(playerName) private void Player(playerName) public Player(String playerName)
Answer: Player(String playerName)
Explanation:
A constructor is a code block of a class. It is always witnessed when a new instance of the class is created
In JAVA , a valid constructor header is given as " CLASS (parameter)"
here, Class → Player
parameter → player name (which is a string)
So, a valid constructor header for the Player class that accepts the player name as a parameter: Player(String playerName)

Which statement is false?It's necessary to include names of pointer arguments in function prototypes.A function receiving an address as an argument must define a pointer parameter to receive the address.The compiler does not distinguish between a function that receives a pointer and a function that receives a single-subscripted array.The function must â knowâ whether it is receiving a sin-gle-subscripted array or simply a single variable for which it is to perform simulated call by reference.
Answer:
The answer is "It's necessary to include names of pointer arguments in function prototypes".
Explanation:
In method prototype, the declaration of the method specifics name and type of methods like arity, parameter type, and return type, but omits the method body, and the correct choices can be defined as follows:
A method which gets an address of the parameter must fix a pointer parameter for all the address to be received. The code compiler doesn't differentiate the received method and a single subscribe array reference or function. Its function should "know" how a single sub-scripted array has been received for which simulated references are required.You asked your colleague to provide feedback on a blog post you recently wrote.

In the classified section of a local newspaper, I came across job openings for the post of a network engineer in two different companies. One was from the airline industry, while the other was from the food and beverage industry.
The airline company required an applicant to have a bachelor's degree in network administration. The job posting specified that applicants with supporting CCENT or CompTIA Security+ certifications would be preferred. The company was willing to consider candidates with no prior experience. The job responsibilities included: maintaining security, DNS, IP routing, firewalls, and troubleshooting IT-related problems. The role also required skills to manage multi-site network operations, operating systems, and other software applications in public as well as private facilities. Another responsibility was to complete the time logs in the company's records to facilitate timely and accurate billing.
For the role of a network engineer in the food and beverage industry, the required qualification was any bachelor's degree in computer science with a minimum of one year of relevant experience. Certifications were an added advantage, but they were not a necessity. The job role required skills to troubleshoot network glitches, monitor network usage, install software and hardware infrastructure, provide technical assistance to users, and suggest improvements in the system.

if a person walks 10 metres due to south in 10 seconds 10 due east in the next 10 seconds and transmitted you're not in the next 10 seconds then he has Dash velocity
Answer:
[tex]\frac{1}{3}\ m/s[/tex]
Explanation:
The computation of the velocity by using the following formula is
As we know that
[tex]Velocity = \frac{Displacement}{Total\ time\ taken}[/tex]
where,
Displacement is 10 meters
Total time taken is 30 seconds
Now placing these values to the above formula
So, the velocity of Dash is
[tex]= \frac{10\ meters}{30\ seconds}[/tex]
[tex]= \frac{1}{3}\ m/s[/tex]
We simply applied the above formula so that we can get the velocity and the same is to be considered

Given the variable ip, already declared as a pointer to an integer, write the code to dynamically allocate memory for a single integer value, assign the resulting pointer to ip, and initialize the integer value to 27.
Answer:
In C++:
int *ip;
ip = new int;
*ip = 27;
Explanation:
First of all, let us have a look at the methods of memory allocation to a variable.
1. Compile Time: The memory gets allocated to the variable at the time of compilation of code only. It is also called static allocation of memory.
Code example:
int a = 5;
2. Run Time: The memory is allocated to the variable on the fly i.e. during the execution of the program. It is also called dynamic allocation of memory.
Now, we have to write code for a variable ip, which is an integer pointer to dynamically allocate memory for a single integer value and then initialize the integer value 27 to it.
Initializing a variable means assigning a value to variable for the first time.
Writing the code in C++ programming language:
int *ip; // Declaring the variable ip as a pointer to an integer
ip = new int; // Dynamically allocating memory for a single integer value
*ip = 27; // Initializing the integer value to 27.

A. The technician should permanently disable all startup processes in System Configuration.
B. The technician should measure the time it takes to start the system using a normal boot and compare that time against the time it takes for the system to perform a clean boot.
C. The technician should back up user data and reinstall Windows and all applications.
D. The technician should disable all scheduled tasks in Task Scheduler and reboot the system.
Answer:
The correct option is;
The technician should measure the time it takes to start the system using a normal boot and compare that time against the time for the system to perform a clean boot.
Explanation:
Clean boot is the process of starting the Windows operating system where the number of drivers as well as startup programs enabled are minimal in order to ascertain if the cause of a slow system startup is due startup interfering programs or drivers
A clean boot operating system startup and a startup in Safe Mode are similar with the difference being the higher level of control on what to run during start up offered by clean boot to aid troubleshooting startup issues.

Consider a text editor that saves a file whenever you click a save button. Suppose that when you press the button, the editor simply (1) animates the button "down" event (e.g., by coloring the button grey), (2) uses the write() system call to write your text to your file, and then (3) animates the button "up" event (e.g., by coloring the button white). What bad thing could happen if a user edits a file, saves it, and then turns off her machine by flipping the power switch (rather than shutting the machine down cleanly)
Answer:
The answer to this question can be defined as follows:
Explanation:
The write() method guarantees you to updates the memory of both the kernel, and may not ensure which updates were flushed through stable storage. Unless the client instead switches on either the monitor but views the file, it displays the file, to combines from older and newer versions will be shown. The very first two cases will be deemed "bad" because the user probably can not expect them after completing the save.
