Answer:
Each object of this class has its own copy of GREETING
Explanation:
option c: Each object of this class has it’s own copy of GREETING
This is the only false statement. When a variable is preceded by the Static key word only one copy of that variable is created, no matter the amount of object created from the instance of that class.
option a: Each object of this class can access GREETING, this is true.
option b: The value of GREETING can’t be changed in any methods, this is true because GREETING is preceded by the keyword final.
option d: GREETING.length() = 2, this is true because the method length() is use to get the length of the string "Hi" which is 2.
option e: GREETING.toUpperCase() = "HI", this is also true because the method toUpperCase() convert all the character of "Hi" to uppercase.
Note: All these are peculiar to java programming language.
Final answer:
Explanation of the incorrect statements regarding the static field declaration in a Java class.
Explanation:
b) The value of greeting can’t be changed in any method: This statement is not true because even though the field is declared as 'final', it can still be accessed and modified using reflection.
c) Each object of this class has its copy of GREETING: This statement is not true. Static fields in Java are shared among all instances of a class, so all objects of the class will have the same value for a static field.
d) GREETING.length() = 2: This is true since the length of the string 'Hi' is 2.

If Windows does not automatically detect a newly added device, to get the device recognized and the drivers installed, you should _________.
Answer:
Update the device driver
Explanation:
Devices drivers are softwares used to link a component of the computer to the operating system functionality.
It normally comes with the installed operating system, but most plug and play devices , come with a little built-in OS that runs once it is plugged in.
If a device is not recognized, update the driver software and restart the system.
To get Windows to recognize a newly added device, manually run the Add Hardware Wizard from the Control Panel, use Device Manager to install drivers, or download drivers from the manufacturer's website.
If Windows does not automatically detect a newly added device, to get the device recognized and the drivers installed, you should manually run the Add Hardware Wizard in Windows. Access the wizard from the Control Panel under Hardware and Sound, or search for it in the Start menu.
Follow the prompts to install the device drivers which can also be found through the Device Manager. It may be necessary to download and install drivers from the manufacturer's website if Windows does not have the appropriate drivers.
You're responsible for technical support at a High School. You're concerned about students with some technical knowledge reconfiguring machines, either maliciously or not. You have already made sure Windows is secure and the students' login has the minimum necessary privileges. What else should you do to prevent students from re-configuring the school lab computers?
Answer:
setup a password for the BIOS
Explanation:
The BIOS refers to Basic Input/Output System. When a BIOS password is set, it will enforce autentication whenever an attempt is made to login at startup. Remember that the computer's microprocessor uses the BIOS to bootup, and it is also responsible for managing information flow between the OS and other devices, therefore very sensitive settings are maintained here, setting up a password will further ensure that that students do not intentionally recomfigure the computers in the school laboratory.
A company has a network address of 192.168.1.64 with a subnet mask of 255.255.255.192. The company wants to create two subnetworks that would contain 10 hosts and 18 hosts respectively. Which two networks would achieve that?
Answer:
192.168.1.96/28 and 192.168.1.64 /27
Explanation:
In computer networking, subnetting is a way of sharing up a network into several more networks. It's importance includes improving routing effectiveness, enhancing security on the network and better managment control. subnetting is acheived by slicing IP address, in the case given in the question, Subnet 192.168.1.64 /27 with 5 bits allocated for the host and will only be able to hold 32 addresses, Subnet 192.168.1.96/28 on the other hand has 4 bits for the host addresses and as such will be able to hold 16 addresses.
"Select the computing device that uses a limited version of an operating system and uses a web browser with an integrated media player.
1. tablet
2. notebook
3. netbook
4. web-based "
Answer:
Web based
Explanation:
Write a method called consecutive that accepts three integers as parameters and returns true if they are three consecutive numbers—that is, if the numbers can be arranged into an order such that, assuming some integer k, the parameters’ values are k, k 1, and k 2. Your method should return false if the integers are not consecutive. Note that order is not significant; your method should return the same result for the same three integers passed in any order. For example, the calls consecutive(1, 2, 3), consecutive(3, 2, 4), and consecutive(–10, –8, –9) would return true. The calls consecutive(3, 5, 7), consecutive(1, 2, 2), and consecutive(7, 7, 9) would return false.
Answer:
#include <iostream>
using namespace std;
void swap(int *a,int *b)
{
int temp;
temp=*a;
*a=*b;
*b=temp;
}
bool consecutive(int k1,int k2,int k3)
{
int arr[]={k1,k2,k3}; //storing these variables into an array
int i,j;
for(i=0;i<3;i++)
{
for(j=i;j<3;j++)
{
if(arr[i]>arr[j])
{
swap(arr[i],arr[j]); //swapping to sort these numbers
}
}
}
if((arr[1]==arr[0]+1)&&(arr[2]==arr[0]+2)) //checks if consecutive
return true;
else
return false;
}
int main()
{
int result=consecutive(6,4,5); //storing in a result variable
if(result==0)
cout<<"false";
else
cout<<"true";
return 0;
}
OUTPUT :
true
Explanation:
In the above code, it stores three elements into an array and then sorts the array in which it calls a method swap() which is also defined and interchanges values of 2 variables. Then after sorting these numbers in ascending order , it checks if numbers are consecutive or not, if it is true, it returns true otherwise it return false.
Laura manages DLP for a large company where some employees have COPE and some have BYOD. What DLP issue could these devices present?
Answer:
For the COPE device, there won't be a lot of risks, because this type of model is very secure and trustworthy. The device belongs to the company and only the corporative use is allowed. The company owns maximum control on the information managed by the device. Some Blackberry devices were only COPE designed.
For the BYOD device, is the opposite, because this type of model is very unsecure since it doesn't count with the security barriers like the COPE model does, leading to the user losing critical information or getting hacked by installing malware. Even though it is a cheaper alternative for a lot of companies, it's far away from beign the most recommendable in terms of security, productivity and privacy.

When using the Insert Function button or the AutoSum list arrow, it is necessary to type the equal sign. True or False?
Answer:
False
Explanation:
It is a general rule for all formulas in Excel and other spreadsheet programs like OpenOffice Calc to begin with the equality (=) sign. However in MS-Excel, when using a function like the AutoSum and Insert as stated in this question scenario, clicking on any of of this functions' button automatically writes out the equality sign. So it will not be necessary to type the equality sign
It is false that typing the equal sign is necessary when using the Insert Function button or the AutoSum list arrow in Excel, as Excel automatically includes the equal sign for these functions.
Insert Function and AutoSum in Excel
It is false that typing the equal sign is necessary when using the Insert Function button or the AutoSum list arrow in Excel. Typically, when you initiate a function through these tools, Excel automatically includes the equal sign at the beginning of the expression. For instance, using the AutoSum feature, Excel will generate a formula (usually a SUM function) that already starts with an equal sign, which precedes the function and its arguments.
Excel formulas are indeed expressions that start with an equal sign and they can be used in calculations and produce results that may include numbers, text, operators, and/or functions. To insert a function quickly, you can also use the keyboard shortcut "Alt" + "=" without typing the equal sign manually.
Entering a formula directly in a cell will also require beginning the input with an equal sign, and in some cases, such as when you're typing the formula manually or editing an existing formula, including the equal sign is essential to let Excel know that what follows is an expression to be evaluated.
In computer science, what are two names that are used to describe data structures organized by association
Answer:
Answer to the following question are,
Association list TablesExplanation:
Because these are the two associations data structures.
Association List: are referred to that data type which contains the pair of the key and item in the Java Programming Language and Python Programming Language, it is called a dictionary data type.Tables or Hash Tables: are referred to that data type which converts the keys into the integer value.Final answer:
In computer science, 'associative arrays' and 'maps' are two data structures organized by key-value associations, which enable efficient retrieval of data.
Explanation:
In computer science, two names that are often used to describe data structures organized by association are associative arrays and maps. An associative array (also known as a dictionary or a map) is a data structure that pairs unique keys with corresponding values.
This allows for efficient data retrieval based on those keys. Similarly, a map is a collection of key-value pairs where each key is unique and is used to store and retrieve data. Both associative arrays and maps are highly useful for situations where quick lookups of associated data are necessary.
Write a static method named printTwoDigit that accepts an integer n as a parameter and that prints a series of n randomly generated numbers. The method should use Math.random() to select numbers in the range of 10 to 19 inclusive where each number is equally likely to be chosen. After displaying each number that was produced, the method should indicate whether the number 13 was ever selected ("we saw a 13!") or not ("no 13 was seen."). You may assume that the value of n passed is at least 0.
Answer: Following code is in java language :-
import java.lang.Math;
public class
{
public static void main(String args[])
{
printTwoDigit(6); //6 is the number of random numbers to be generated
}
public static void printTwoDigit(int n)
{
int i = 0;
int arr[]=new int[n]; //will declare a array of n size
int flag=0;
while(i<n)
{
arr[i] = 10 + (int)(Math.random()*10); //produce random number each time
System.out.println(arr[i]+" "); //print all random numbers
i++;
}
for(i=0;i<n;i++)
{
if(arr[i]==13) //to check if 13 was generated
{
flag=1;
break;
}
}
if(flag==1)
System.out.println("we saw a 13"); //this line is mentioned in question
else
System.out.println("no 13 was seen"); //this line is mentioned in question
}
}
OUTPUT :

we saw a 13
Explanation:
In the above code, an array is declared with size n(which is passed as an argument to the function) to store the list of all random number produced.Random() is multiplied by 10 so that it can produce a number 10 numbers starting from 0 and then 10 is added to the generated number so that minimum value generated would be 10.All numbers generated are printed to console n times and stored in arr.After that arr is checked for value 13 so it can print whether 13 was produced or not.Final answer:
The printTwoDigit method generates n random numbers between 10 and 19 using Math.random(), checks if the number 13 appears, and prints a corresponding message.
Explanation:
The method printTwoDigit generates and prints a series of random numbers between 10 and 19, using the Math.random() function. To generate numbers specifically in the range of 10 to 19, we can multiply the result of Math.random() by 10 and then add 10 to shift the range. After generating each number, the method checks if the number 13 was generated and prints a message accordingly. If at least one instance of the number 13 appears during the sequence, the message "we saw a 13!" is displayed; otherwise, the message "no 13 was seen." is shown.
Here is an example implementation of the method:
public static void printTwoDigit(int n) {
boolean saw13 = false;
for(int i = 0; i < n; i++) {
int randomNum = (int)(Math.random() * 10) + 10;
System.out.print(randomNum + " ");
if(randomNum == 13) {
saw13 = true;
}
}
System.out.println();
if(saw13) {
System.out.println("we saw a 13!");
} else {
System.out.println("no 13 was seen.");
}
}

Users feedbackManaging coursesTrack student attendanceWhich routing protocol does an exterior router use to collect data to build its routing tables?
A. OSPFB. IPC. RIPv2D. BGP
Answer:
D. BGP
Explanation:
In order to exchange routing information with another AS (Autonomous Systems) only, exterior routers use an exterior routing protocol, like BGP (Border Gateway Protocol) or EGP (Exterior Routing Protocol).
BGP is an application-layer protocol in the TCP/IP suite, that uses a well-known TCP port (179) in order to deliver information reliably.
It is important to note that in order to exchange routing data within his own AS, the router uses an interior routing protocol, like OSPF.
