Answer: Procedure division

Explanation:

 The SORT statement is basically used in the procedure division for placing the various records in the sort file. The SORT statement easily accept the records from the different files and then sorting them accordingly to the specific file key in the database.

The SORT statements are used in the procedure division but it does not used in the declarative portion in the sorting file. The SORT statement is basically coded in the form of independent and fixed segment.

Answer: (C) Unicast

Explanation:

 According to the question, if we sending an email to someone individually then, uni-cast addressing type is used. The unit addressing is basically used to represent the single local area network interface.

The unit-cast frame sent only to the specific devices not to the group of the devices. The unitcast basically use between the one source to the one destination.

On the other hand, multicast and broadcast are incorrect because the frame sent to the group of the devices not the specific devices. Therefore, Option (C) is correct.

Note. Consider changing the cell in yellow, does not make sense, it could be 10100 instead of 1010

Hi, to design this sheet, I also used the and(...) function of MS excel, in which you declate that in order to select a certain answer, 2 or more conditions must be true, in our case, if a purchase is up to 1000, the price would be $1010 (consider changing this value, maybe to 10100), if the purchase is more than 1000 and less than 5000, the price is $9,509.50, and if is more than 5000 units, the price would be $5,5005.50.

Please check the formula for further clarifications.

Best of luck.

Final answer:

To calculate unit prices and total cost in Excel with VLOOKUP for quantity discounts, create a lookup table with quantity thresholds and prices, then use the VLOOKUP formula to find the unit price for any order quantity, and multiply this price by the order quantity to find the total cost.

Explanation:

To develop an Excel template that calculates the unit price using quantity discounts with the VLOOKUP function, you'll first need to set up a table with the quantity thresholds and the corresponding unit prices. This table will act as a lookup table for the VLOOKUP function. You will then create a formula that takes an order quantity as input and returns the appropriate unit price based on the quantity thresholds specified.

Here’s an example of how you might structure your table (note that the actual table should be placed in the Excel sheet):

To use the VLOOKUP function, you’ll enter a formula like the following in the cell where you want to display the unit price:

After finding the unit price, you can compute the total cost of the order by multiplying the quantity by the unit price derived from the VLOOKUP result:

Answer:

The answer to this question is "false".

Explanation:

In this question, the answer is wrong because in computer science. Except for the binary language, It didn't understand any language. In computer 1 stands for true value and 0 stands for false value. In If-else statement if block executes true value is that is 1. and else block execute false value that is 0. In this question, if the value is 1 then the answer is true. But the answer to this question is false.

Answer:

// here is code in c++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main() {

// variable

int num;

int tot_sum=0;

cout<<"enter a number: ";

// read the value of n

cin>>num;

// check the multiple of 2 or 5 from 1 to n

for(int x=1;x<=num;x++)

{

// if multiple of 2 or 5 then add them

   if(x%2==0 ||x%5==0)

   {

       tot_sum=tot_sum+x;

   }

}

// print the sum

cout<<"sum of multiple of 2 or 5 is:"<<tot_sum<<endl;

return 0;

}

Explanation:

Read the number "n" from user.Check every number from 1 to n, if it is a multiple of 2 or 5 then add them to "tot_sum".When the for loop end, "tot_sum" will have sum of all the number which are either multiple of 2 or 5.Print the sum.

Output:

enter a number:11

sum of multiple of 2 or 5 is:35

Answer: Perform calculations on entire columns of data

Explanation:

 Data aggregate is the process that gather the information and express into the form of summary. It basically used in the statistical analysis for calculating the entire column of the data.

The main purpose pf the data aggregate is that it collect more data or information about the specific variable of the given data. The data is basically available in the form of aggregate.

The data aggregate function easily produced the summarized data in the database.

int main()

{

// variables

   int a,b,c;

   //ask to enter semester hours

   cout<<"Enter the number of hours in the semester:";

   // read the semester hours

  cin>>a;

  //print the semester hours

  cout<<"You have taken "<<a<<" hours in semester."<<endl;

  // find the time spend outside of the class

  b=a*2;

  c=a*3;

  // print the time outside class

  cout<<"you should spend "<<b<<"-"<<c<<" hours outside of class"<<endl;

return 0;

}

Explanation:

Read the hours taken in the semester from user and assign it to "a".

Then find its 2 and 3 time.This will be the time user should spend outside

of the class.

Output:

Enter the number of hours in the semester:15

You have taken 15 hours in semester.

you should spend 30-45 hours outside of class

Explanation:

The precision in double values is twice as compared to float values.Hence double have smaller rounding errors as compared to float variables .A double is of 64 bits and float is of 32 bits usually hence floats have more rounding errors and on more number than doubles.Double has 15 decimal digits of precision and float has only 7 decimal digits for precision.

Answer:

 Parallel processing is the type of the processing in the computer program instruction by divide into the multiple processors unit. The parallel processing basically allow the interleaved execution the given program together.  

The parallel processing basically uses the multiple element for processing the solution of the problems simultaneously. it basically divide the problem  into independent parts so that the processing of the elements can execute simultaneously.

Its main objective of the parallel processing is that compile and run the program in short duration or time.  

Answer:

many forms

Explanation:

Polymorphism is a construct in object oriented programming which means multiple forms.For example: Suppose I have a function which performs the add operation on two integers and another function with the same name which concatenates 2 given strings:

The two functions represent polymorphic forms of the add function. The function to be invoked at runtime is determined by the runtime argument type.

For example , add (2,3) will invoke int add ( int a, int b);

Similarly, add("hello","world") will invoke string add ( string a , string b);

Answer: D)The pattern of blood vessels at the back of the eye.

Explanation: The retinal scan is the techniques which is used in the bio-metric mechanism.The scanning of the retina's blood vessel pattern is capture by the scanner is the unique technique which is used for bio-metric purpose.

Blood vessel pattern is capture because it is present in unique form for every person and will help in distinguishing a person from another person while scanning.

Other options are incorrect because light reflection or reaching near retina and light pattern are not the unique way for identification while scanning a person.Thus the correct option is option(D).

Answer: (A) SQL injection

Explanation:

 Th SQL ( Structured query language) injection is the code injection method or technique that is basically used in data driven attack various applications. The SQL injections are basically used by hackers for attacking on various websites.

The SQL injection are used by the hackers to insert the malicious structured query language statement in the input state for the execution process in the database.  

When we use the SQL injection during that process, the attacker can easily access and modify the database.

Answer:

C. Bell and LaPadula

Explanation:

The first mathematical models of multilevel security computer system was developed by Bell and Lapadula. Their full names are David Elliot Bell and Leonard J. Lapadula. Their model used to define the concept of modes of access,secure state machine and outlined the rules of access.

Answer:

Following are the program in c++ language

#include<iostream> // header file

using namespace std; // namespace

int main()  

{

int n1,i; // variable declaration

cout<<"Enter Number: ";

cin>>n1; // input number

for(i=n1;i>1;i=i-2) // check the condition  

{

n1 = n1-2; // decrement the value of number by -2  

}

if(n1==0) // check if it is 0

cout<<"number is EVEN"<<"\n"; // print even

else

cout<<"number is ODD"<<"\n"; // print odd

return 0;

}

Output:

Enter Number: 45

number is ODD

Again run the program

Enter Number:10

number is EVEN

Explanation:

In this program, we input the number by a user in variable n1. After that, we iterate the for loop and initialize the value of a variable" i" in for loop and check the condition.

In each iteration, the variable n1 is decrement by 2 and store it n1.

Finally, check if n1==0 then it print number is EVEN  otherwise it print number is ODD.

Answer:

Bootloader is the program that helps in the revitalizing the micro-controller of the operating system .It makes the operating system self programmable.It's main purpose is loading the tasks or operations to ensure the working interface between software and hardware whenever the system gets booted up.

It is also known as the bootstrap loader.It is necessary and common because it is the first mechanism that works whenever the system gets initialized or booted. Without this feature the reloading of the programs will  not be possible.

Answer:

Comparison.

Explanation:

When we have to find a largest in a list of n elements.First we have to iterate over the list so we can access all the elements of the list in one go.Then to find the largest element in the list we have to initialize a variable outside the loop with the minimum value possible and in the loop compare each element with this value,if the element is greater than the variable assign the element to the variable.Then the loop will find the largest element and it will be the variable.

Answer:C) Feedback

Explanation: System control is the controlling and managing activity of the system by commands ,regulations, management practices etc.It helps in the analyzation of the system and improving the ability of performing the tasks.Feedback is the component of the control system that is obtained as the output after the controlling  technique is applied in the system.

Other options are incorrect because environment is the surrounding of the system ,interface is the connection between the components of the system and boundary is not a technical term of control system.Thus, the correct option is option(C).

Answer:

b. join

Explanation:

Correct answer:

Join: It allow join(paste) two tables by one or more commun columns

Example in the image attached

Bad answer:

Union: it only allow paste two tables with the same structure

select: it only allow get information from 1 table if not use join

having: it only allow get filtered information with a condition

Answer:

#include <iostream>

using namespace std;

int main() {

   int n,*p;

   cin>>n;//taking input.

   *p=n;//passing the address of n to pointer.

   cout<<*p<<endl;//printing the number using the dereferncing operator.

return 0;

}

Explanation:

The above written program in in C++.This program takes input of the integer n and stores the address of the integer in the pointer p. For printing the value of the to which the pointer is pointing we need to used the dereferencing  operator * .

Answer:

#code in python.

#function that calulate 2 numbers are relatively prime or not

def fun(x,y):

   while(y):

       x,y=y,x%y

   return x

#user input

a=int(input("enter first number:"))

b=int(input("enter second number:"))

#call the function

if(fun(a,b)==1):

   print(" Both numbers are Relatively prime")

else:

   print("Both numbers are Not relatively prime")

Explanation:

Read two numbers from user.Call the function fun() with parameter "a" & "b". In the function, it will perform Euclid algorithm to find the greatest common divisor.If it is 1 then both are relatively prime else both are not relatively prime.

Output:

enter first number:5

enter second number:125

Both numbers are Not relatively prime

enter first number:8

enter second number:9

Both numbers are relatively prime

Answer:

a. 4

b. 3

c. pi

Explanation:

Generic formula of a sine wave: s(t) = Amp * sin ( 2*pi*freq*t + phase)

where, Amp => Amplitude

freq => frequency

phase => phase

Given sine wave: s(t) = 4sin(2π3t + π)

Comparing it with the generic form , we can identify that :

a. Amplitude : 4

b. Frequency : 3

c. Phase : pi

Amplitude measures peak displacement from origin, Frequency is the number of cycles per second and phase is the relative positioning of the wave with respect to the origin.

Answer:

1) Amplitude = 4

2) Frequency  =[tex]1Hz[/tex]

3) Initial phase = [tex]\pi [/tex]

Explanation:

The general equation of wave is

[tex]y(t)=Asin(\omega t+\phi )[/tex]

where

A is the amplitude of the wave

[tex]\omega [/tex] is the angular frequency of the wave

[tex]\phi [/tex] is the initial phase of the wave

The given wave function is

[tex]s(t)=4sin(2\pi t+\pi )[/tex]

Comparing with the standard function we get

1) Amplitude = 4

2) Frequency  =[tex]\frac{\omega }{2\pi }=\frac{2\pi }{2\pi }=1Hz[/tex]

3) Initial phase = [tex]\pi [/tex]

The answer is B because cyber crime is when a computer is used to commit criminal activities.

Answer:

Following are the program in c++

#include <iostream> // header file

using namespace std; // namespace

int main() // main function

{

double a,b; // variable declaration

cout<<"Enter the first number and second number : \n";

cin>>a>>b; // input the number

if(a>b) // check first number greater than second number

{

cout<<"The first number you entered is larger";

}

else

{

cout<<"The second number you entered is larger";

}

return 0;

}

Output:

Enter the first number and second number :

45.5

687.8

The second number you entered is larger

Explanation:

In this program we have declared two variable i.e a and b of double type. After that check the condition if(a>b) if this condition is true then display  the message "The first number you entered is larger " otherwise display the message  "The second number you entered is larger".

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

   // variables

double price,fee,tax;

double total;

cout<<"enter the price of car:";

// read the price of car

cin>>price;

cout<<"enter the fee:";

// read the fee

cin>>fee;

cout<<"enter the tax (in %):";

// read the tax

cin>>tax;

a

// total cost

total=price+fee+(price*tax)/100;

// print the cost

cout<<"total cost is: "<<total<<endl;

return 0;

}

Explanation:

Read the price of the car from user and assign it to variable "price",read fee and assign it to variable "fee" and tax to variable "tax".Then calculate the total cost of the car by adding the fee and tax of car to the price of car.

Output:

enter the price of car:1000

enter the fee:50

enter the tax (in %):10

total cost is: 1150

Answer: Lead time

Explanation:

 Minimizing the lead time is one of the key to maintain the competitive edge. Lead time is basically defined as the time period between production of the product to the product are get manufactured in the market. It is also known as time to market.

it basically gives competitive edge when the lead time is reduced over the other products with the high lead time.

The main advantage of the lead time is to make reduce the lead time so that the organization can provide the fastest and reliable delivery of products and services.
