Answer:
The answer is "Option B"
Explanation:
The PSU stands for "power supply unit", it is an internal component of a device which is used to convert current AC to DC power that is controlled by low-voltage, and other choices are not correct, that is explained as follows:
In option A, HDD is used to store data, that's why it's wrong. In option C, It is a small memory chip, that is used to hold data. In option D, It is a device that is used to add a graphics card, that's why it is not correct.Given a double variable named x that has been declared and given a value, let's use a binary search technique to assign an estimate of its square root to another double variable, root that has also been declared. Let's assume that x's value is greater than 1.0 -- that will simplify things a bit. Here's the general idea:
Since x>1, we know its square root must be between 1 and x itself. So declare two other variables of type double (a and b say) and initialize them to 1 and x respectively. So we know the square root must be between a and b. Our strategy is to change a and b and make them closer and closer to each other but alway make sure that the root we're looking for is between them. (Such a condition that must always hold is called an invariant.)
To do this we will have a loop that at each step finds the midpoint of a and b. It then squares this midpoint value and if the square of the midpoint is less than x we know that the root of x must be bigger than this midpoint: so we assign the midpoint to a (making a bigger and shrinking our a and b interval by half!)-- and we still can be sure that the root is between a and b. Of course if the midpoint's square is greater than x we do the opposite: we assign b the value of midpoint.
But when to stop the loop? In this exercise, just stop when the interval between a and b is less than 0.00001 and assign root the midpoint of a and b then.
We call this a binary search also because at each stage we cut the interval under consideration in half. Efficient as this method is, old Isaac Newton discovered an algorithm that is even more efficient and that's what the library function sqrt uses.
I have this:
double a=1, b=x;
double mid;
while(a-b>0.00001){
mid=(a+b)/2;
mid=mid*mid;
if (mid
a=mid;
else if(mid>x)
b=mid;
else
root=mid;
}

A(n) _____ prevents a mobile device from being used until the user enters the correct passcode.
a. personal ID reader (PIDR)
b. lock screen
c. magnetic carriage
d. swipe card
Answer:
b. lock screen
Explanation:
Lock screen is a security feature provided by many mobile operating systems in mobile devices. This feature prevents unauthorized access to the device. This feature does not allow the mobile to be used unless the user performs a specific action rightly in order to get access of the mobile device. This action can be entering the correct password, pin-code, pattern. These days, the lock screen with new enhanced security features enables the users to unlock the mobile device using gestures like face recognition and also provides fingerprint lock feature that locks and unlocks the mobile device with the fingerprint of that device user. Its a good practice to set the lock screen in a way that it locks the device if it remains idle for specific time and the user is required to enter the password etc to unlock it. Lock screen is a beneficial feature when it comes to the security of the device and the data stored in it.___________ is Google’s machine-learning artificial intelligence system that interprets people’s searches to find pages that might not have the exact words they searched for.
Answer:
RankBrain
Explanation:
RankBrain is a machine learning-based search engine algorithm, the use of which was confirmed by Google on 26 October 2015. It helps Google to process search results and provide more relevant search results for users.
Final answer:
RankBrain is Goog.le's AI system that helps interpret user searches for more effective results, considering factors like paid ads, popularity, and web connectivity. Search engine rankings are not based solely on content accuracy, so users should use approaches like SIFT to evaluate the credibility of information found online.
Explanation:
RankBrain is Goog.le’s machine-learning artificial intelligence system that interprets people’s searches to find pages that might not have the exact words they searched for. When using search engines like Goog.le, it's important to understand that results are not solely ranked based on authority, accuracy, or relevance. Instead, factors such as paid advertisements, popularity, and web interconnectivity can influence the visibility of web pages in search results.
As a result, it is possible for websites disseminating misinformation to manipulate search engine optimization (SEO) tools to boost their ranking in the search results. Therefore, users should exercise critical judgment and employ the SIFT method, which stands for the four moves of student fact-checkers, to assess the credibility of the sources they find online.
A program is used to convert from minutes to seconds. Write the directive for defining the conversion factor called MINUTE_TO_SECOND_FACTOR as a constant that cannot be changed and define it as a string 60.
Answer:
I am writing a simple program in C++ However, let me know if you need this program to be implemented in some other programming language .
Program#include <iostream>
using namespace std;
#define MINUTE_TO_SECOND_FACTOR 60
int main()
{ int minutes;
cout<<"enter the time in minutes: ";
cin>>minutes;
int output;
output = minutes * MINUTE_TO_SECOND_FACTOR;
cout<<minutes<<" minutes = "<<output<<" seconds.";
Output:enter the time in minutes: 45
45 minutes = 2700 seconds
Explanation:I will explain every line of the code .
The first statement contains a pre-processor directive which is a library that contains input and output functions for a program.The next line namespace is used so that the computer can identify cout, cin and endl used in the program.This is a define directive #define MINUTE_TO_SECOND_FACTOR 60Here define directive is used for declaring a macro which is MINUTE_TO_SECOND_FACTOR. Here this macro is given a value 60. Now wherever in the program this macro is used, it will be replaced by 60. This macro MINUTE_TO_SECOND_FACTOR can be used as a constant and cannot be changed.Next line enters the body of the main function.variable minutes is declared which is used to store the value in minutes. variable is declared which will store the result of the conversion from minutes to seconds.output = minutes * MINUTE_TO_SECOND_FACTOR; statement works as follows:In this statement written above the value of minutes is multiplied by 60 ( value of the macro MINUTE_TO_SECOND_FACTOR) and the result of this multiplication is stored in the output variable.
As we know that 1 minute =60 secondsLet suppose the input number is 45 minutesThen output= 45 * 60
output= 2700 seconds.
Last statement displays the converted value of minutes into seconds which is stored in output variable.Print a message telling a user to press the letterToQuit key numPresses times to quit. End with newline. Ex: If letterToQuit = 'q' and numPresses = 2, print:Press the q key 2 times to quit.Sample program:#include int main(void) { char letterToQuit = '?'; int numPresses = 0; return 0;}
Final answer:
To tell a user to press a certain key a number of times to quit in C, you can use the printf function to format and print the instructions, simply adjusting the variables for the key and number of presses.
Explanation:
The student is asking for assistance in writing a C programming code that prompts a user to press a specific key a certain number of times to perform an action, such as quitting a program. In this scenario, the student needs to complete the program by adding a statement to do this. Here's how you can write the code inside the main function:
#include <stdio.h>
int main(void) {
char letterToQuit = 'q';
int numPresses = 2;
printf("Press the %c key %d times to quit.\n", letterToQuit, numPresses);
return 0;
}
This code snippet sets the letterToQuit to 'q' and numPresses to 2, then it prints the message to the user. Adjust the variables letterToQuit and numPresses as necessary for different requirements.

What is wrong with the following code fragment? int *p1, *p2; p1 = new int; p2 = new int; *p1 = 11; *p2 = 0; p2 = p1; cout << *p1 <<" " << *p2 << endl; delete p1; delete p2;
Answer:
Hi Hannahdavy! This is a good question. The problem lies in this part of the program:
p2 = p1;
Explanation:
In C/C++, memory is manually managed. When the variable p1 is assigned to variable p2, the memory allocated for p1 is left unmanaged, causing memory issues. Therefore the program will throw a “double free or corruption (fasttop)” error. What is needed to resolve the issue is to either (a) assign a null value to p1 after p1 has been assigned to p2, or (b) remove the p2 assignment of p1, depending of what the function is actually trying to do in the program.

Encapsulation means ________. 1. that data fields should be declared private2. that a class can extend another class 3. that a variable of supertype can refer to a subtype object 4. that a class can contain another class
Answer:
Option 1 is the correct answer for the above question.
Explanation:
Encapsulation means rapper the data or variable or method on some pack and denies to give direct access for any private data. The above question wants to ask about the Encapsulation. The option 1 is correct for its because this option suggests a scenario, where a class field is declared as private and we know that private data members of the class can not be accessed by outside the class. It can access only the inside of the class. So it proves both the property of encapsulation one is to rapper the data and the other is to deny the directly accessed outside. So this option is correct while the other is not because--
Option 2 states that another class is extended by the base class which is not the property of encapsulation. Option 3 states that a sub-type object can be referred by the variable of super-type which is also not the property of encapsulation. Option 4 states that a class is contained by the other class which does not hold both the property of encapsulation.QUESTION 4 A(n) _____________ is a set of rules that determine what a layer would do and provides a clearly defined set of messages that software at the layer needs to understand. a) agreement b) specification c) protocol d) regulation policy.

What is output by the following C# code segment?int temp;temp = 180;while ( temp != 80 ) {if ( temp > 90 ) {Console.Write( "This porridge is too hot! " );// cool downtemp = temp – ( temp > 150 ? 100 : 20 ); } // end ifelse {if ( temp < 70 ) {Console.Write( "This porridge is too cold! ");// warm uptemp = temp + (temp < 50 ? 30 : 20);} // end if} // end else} // end whileif ( temp == 80 )Console.WriteLine( "This porridge is just right!" );
Answer:
This porridge is too hot! This porridge is just right!
Explanation:
I am going to explain every line of the given C# code to give explanation of the output.
The first statement int temp declares a variable temp.Then the temp variable is assigned a value 180.The block of statement in while loop body will keep executing until the value in temp variable gets equal to 80. The while loop first checks if the value of temp is not equal to 80. As the value of temp=180 which is not equal to 80, this means that the condition of while loop evaluates to true so the block of code in the body of the loop is reached.There is an if condition inside while loop which checks if the value in temp variable is greater than 90. As value of temp=180 which is greater than 90 so the condition is true. As the condition in the if statement evaluates true so the block of code which is the part of this if statement will be executed:{Console.Write( "This porridge is too hot! " );
temp = temp – ( temp > 150 ? 100 : 20 ); }
The first statement is executed which displays this message: This porridge is too hot! Next temp = temp – ( temp > 150 ? 100 : 20 ); statement will change the value of temp. It has the conditional operator which works as follows:Here, temp>150 is the condition to be evaluated.
If this condition is True then 100 will be returned else 20 will be returned. The value returned is then subtracted from the value of temp and the subtraction result will become the new value of temp. As the value of temp which is 180 is greater than 150 so 100 is returned and is subtracted from the value of temp (180).temp= 180-100
temp=80
So the new value of temp is 80.The else part will not be executed because the condition in if statement was true and also we can see that temp is not less than 70. It means that the porridge is too cold part will not be executed.The while loop while(temp!=80) will again be checked. As the new value of temp is now 80, so the condition gets false which breaks the while loop and program control will leave the body of while loop. After the control comes out of the while loop, there is another if statement. This statement checks if the value of temp variable is equal to 80. It is true as the new value of temp is now 80 after that execution of while loop block of code. As the if condition evaluates to true the statementConsole.WriteLine( "This porridge is just right!" );
will be executed which displays the message:
This porridge is just right.
Hence the output of the given code is:This porridge is too hot! This porridge is just right!
You are the administrator for the CorpNet domain. The CorpDC and CorpDC3 servers are the DNS servers for the domain. You are responsible for CorpDC, which resides in Building A. Users report that they are unable to contact the CorpWeb server.
Complete the following:
1. Ping the CorpWeb server using its full name (CorpWeb.CorpNet.local). What happens?
2. Ping the CorpWeb server using its IP address (192.168.0.15). What happens?
3. Create any DNS records needed to fix the problem.
4. Use the Ping command to verify that the problem has been fixed.
Final answer:
To troubleshoot the DNS issue, first ping the CorpWeb server by name and then by IP. If only the name fails, create the correct DNS A record. Verify the solution with a final ping.
Explanation:
The inability to contact the CorpWeb server possibly indicates a DNS resolution issue. Here's how to troubleshoot and fix the problem:
Ping the CorpWeb server by its full name. If there is no response, this suggests a DNS resolution problem.
Ping the CorpWeb server by its IP address (192.168.0.15). If this is successful, it confirms that the issue lies with DNS rather than connectivity.
Create or correct the A record for CorpWeb in the DNS server. The A record should point the server's fully qualified domain name (FQDN) to its IP address.
Use the ping command again to verify that the DNS problem has been resolved and that CorpWeb.CorpNet.local now responds.
Final answer:
The issue with contacting the CorpWeb server can be addressed by checking DNS resolution through pinging the server by name and by IP address. A corrective action is to verify and create the necessary A record in DNS. Once the record is set, a successful ping by server name confirms resolution of the issue.
Explanation:
To address the issue where users are unable to contact the CorpWeb server, follow these troubleshooting steps:
Ping the CorpWeb server using its full name (CorpWeb.CorpNet.local). If the ping fails, it indicates that there may be a DNS resolution issue.
Ping the CorpWeb server using its IP address (192.168.0.15). If this ping is successful, it further confirms that there is a DNS problem, since the server is reachable by its IP address but not by its full name.
To fix the issue, log into the DNS management console on CorpDC and create or correct the A record for CorpWeb.CorpNet.local to point to the correct IP address, which is 192.168.0.15.
Finally, use the Ping command again to verify that the problem has been fixed. If the ping to CorpWeb.CorpNet.local is successful, then users should now be able to contact the CorpWeb server by its full name.
