B JSP and servlets.
C Active Server Pages (ASP).
D Practical Extraction and Report Language (PERL).
Answer:
B JSP and servlets.
Explanation:
Server Side Includes (SSI) is a simple interpreted server-side scripting language used almost exclusively for the web.JSP and servlets; A servlet is a server-side program and written purely on Java. JSP is an interface on top of Servlets.Active Server Pages (also known as ASP) is Microsoft's first server-side script engine that enabled dynamically-generated web pages. Practical Extraction and Report Language (Perl) is a language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information.All formulas that begin with =IF will
A. change the formatting of a cell in a specific way if certain conditions are met.
B. return a specific value, calculation, or message if certain conditions are met.
C. always copy the contents of the adjecent cells if they contain data.
D. remove contents from a cell if they will likely cause an error during calculations.
Answer:
return a specific value, calculation or message if certain condition met
Explanation:
"if" is used for conditional statements that means, do some work if the condition is met against that logic.
e.g.
If (a > 5)
{
Show "a is greater than 5"
}
so if we put a= 6 than condition met and given statement will be shown on out put as "a is greater than 5".

Because many of the online shoppers has unable to inspect that items which they are buying from online and they considered same as they see on the stores' template but sometimes these outlets are cheaper in pricing but also cheap in quality also because they don't know what type of quality they are buying.
Assume that input file references a Scanner object that was used to open a file. Which of the following while loops shows the correct way to read data from the file until the end of the file is reached?
a) while (inputFile != null)
b) while (!inputFile.EOF)
c) while (inputFile.hasnextInt())
d) while (inputFile.nextLine == " ")
Answer:
The correct answer to the following question is an option c) while (inputFile.hasnextInt()).
Explanation:
hasnextint() is the function of the scanner class which is "java.util.Scanner".
This method returns the boolean value so the data type of this method is boolean.
Integer values of radix are assumed only when a next token is in the Scanner input and it returns output True.
The other options are false because the input file can be null and the end of file is not equal to the input file and the next line is equal to the space and also the other options are not the object of the scanner class.
Assume you have the following array: int[] values = new int[15]; What will happen if the following code is executed? int[15] = 20;
a. The value will be added to the array.
b. You will get an ArrayIndexOutOfBoundsException
c. Nothing will happen
d. The array will grow in size by one and the value will be added to the array.
Answer:
You are creating an array "values" which stores 15 integers. And if we will write int[15]=20, we are not following correct syntax. Hence, nothing will happen, and it might however, throw an error that the syntax is wrong.
Explanation:
int[15]=20 is a wrong syntax, and hence nothing will happen or computer might throw an error like that not correct syntax is being used. And if we write values[15]=20, It will certainly throw ArrayIndexOutOfBoundsException as the maximum length is fixed to 15 and values[14] and not more than that.
Assume the existence of an interface, Account, with the following methods: deposit: accepts an integer parameter and returns an integer withdraw: accepts an integer parameter and return a boolean Define a class, BankAccount, that implements the above interface and has the following members: an instance variable named balance a constructor that accepts an integer that is used to initialize the instance variable an implementation of the deposit method that adds its parameter to the balance variable. The new balance is returned as the value of the method. an implementation of the withdraw method that checks whether its parameter is less than or equal to the balance and if so, decreases the balance by the value of the parameter and returns true; otherwise, it leaves the balance unchanged and returns false.
Answer:
The code to this question can be given as:
Code:
public class BankAccount implements Account //define class that inherit interface Account.
{
private int balance; //define integer variable.
public BankAccount(int x) //define parameterized constructor.
{
balance = x;
}
public int deposit(int x) //define function deposit.
{
balance =balance+ x;
return balance;
}
public boolean withdraw(int x) //define function withdraw.
{
//conditional statements
if (x <= balance) //if block
{
balance = balance - x; //calculate value.
return true; //return value.
}
else //else block
{
return false; //return value
}
}
}
Explanation:
The description of the above code can be given as:
In this code we define a class that is "BankAccount" this class inherits the interface that is "Account". for inheriting the class to the interface we use implements keyword to inherit class to interface. In this class we also define an integer variable that is balance. Then we define a parameterized constructor. In this constructor, we pass an integer variable that is "x" as a parameter. In this constructor, we use the balance variable to hold the constructor parameter value.Then we define a function that is a deposit() and withdraw(). In both functions, we pass an integer variable that is "x". In the deposit() function we use a balance variable for calculating value and return its value.and in the withdraw() function we use conditional statement. In this, we check if function parameter value that is x is less then equal to balance so we calculate the balance and return true. else we return false.A ________ is a person or organization that seeks to obtain or alter data or other IS assets illegally, without the owners' permission.

Linda installed a special pool for the hydrotherapeutic treatment of severe arthritis, as prescribed by her doctor. The cost of installing the pool was $22,400, and her insurance company paid $5,600 toward its cost. The pool increased the value of Linda's house by $7,840, and it has a useful life of 10 years. How much of a deduction (before any AGI limitations) is Linda entitled to in the year of installation of the pool?
Answer:
Linda is entitled to deduction (before any AGI limitations) of $896 in one year of installation of the pool.
Explanation:
Following is explained calculation for deduction (before any AGI limitations) that is Linda entitled to in the year of installation of the pool.
Given that:
Cost of Installing the pool = $22,400
Paid by insurance company = $5,600
So by deducting the price paid by insurance company from total cost the balance becomes:
Balance = $22,400 - $5,600 = $ 16,800
As the pool increased the value of house by $7,840 so we will deduct this amount from balance:
Balance = $ 16,800 - $7,840 = $8,960
As the useful life given for pool is 10 years so we will divide the balance with 10 to obtain the deduction amount for 1 year:
Deduction amount for one year = $8,960/10 = $8,96
Hence $8,96 will be deducted in one year installation.
i hope it will help you!
The advent of mobile systems run by Android and other operating systems opens a wide range of new system management and security concerns for systems administrators, including the _____ paradigm in which an organization’s members connect their personal devices directly to a secured network.
Answer:
bring your own devices
Explanation:
"bring your own devices" paradigm is getting popular since organizations are increasingly allowing users to perform work tasks on their own personal devices, It is preferred because of the benefits and ease for the user. On the other hand, this paradigm opens several security risks.
For example processing sensitive data on personal devices creates risks in case of data recovery or if the device is stolen or lost.
Additionally, control and monitoring of organizational data is harder when users allowed to work on their personal devices. Thus data leakage and public exposure can happen more easily.
What occurs when you call a method on a reference variable that contains null? Select one: a. An ArrayIndexOutOfBoundsException error b. An ArithmeticException error c. A NullPointerException error d. A ClassCastException error
Answer:
Option(c) i.e "A NullPointerException error " is the correct answer for the given question.
Explanation:
Exception are the run time error in the program.A NullPointerException is the runtime error when the pointer containing the NULL value .This type of exception occur when we call that function on the pointer variable which contains the NULL.
ArrayIndexOutOfBoundsException error occur when we accessing the element which is out of the index or bound so this option is incorrect.An ArithmeticException error occur in the arithmetic operation. Suppose a number is divided by zero then the ArithmeticException error is occured .ClassCastException error occur in the typecasting of a specific object.So this option is incorrect.In the process view of business, which of the following should be identified when defining the system?

B. drains water directly into the ocean. C. is an interconnected group of streams that collects water over a large area. D. is a trunk stream that cuts across a resistant ridge.
Final answer:
A trellis drainage network forms in folded topography where main channels and tributary streams resemble a garden trellis, typically seen in regions like the Appalachian Mountains. It is distinct from other patterns, such as dendritic or radial, which are influenced by different geographical and geological factors.
Explanation:
A drainage network is considered a trellis network, which is answer A, when rivers flow over a folded topography, such as that found in the Appalachian Mountains. In a trellis drainage pattern, the main streams and tributaries resemble a garden trellis, where down-turned folds known as synclines create valleys that host the main channel. Tributary streams enter these channels at sharp angles, following the ridges known as anticlines. This contrast to dendritic patterns, radial patterns, and other types of drainage networks that form in different conditions, such as over homogeneous material or around central elevated points like volcanoes. Comparing a trellis drainage pattern to other drainage patterns provides insight into the local topography and subsurface geology that dictate the drainage network. Over time, streams within these networks develop gradients, where the inclination reduces from the headwaters to the mouth. Geologic events, such as folding and faulting, can greatly influence the development of these patterns, as can the type of rock present in the region.

a. active array sequencing
b. buffer overrun protection
c. array bounds checking
d. scope resolution binding
Answer:
The correct option to the following question is an option (c) array bounds checking
Explanation:
Array bound checking is the checking is the checking of the elements of an array, when the number of the array goes beyond the number of array that is given at the time of declaration of the array.
This time if the programmer executes the program than an error arises that is 'IndexOutOfBoundsException'.
For Example:
//import packages
public class A { //define class
//define main function
public static void main(String args[]) {
int[] ar = {8, 6, 7, 0, 2, 23, 7}; //set integer array type variable
System.out.println("Array are:: "); //print message
System.out.println(Arrays.toString(ar)); //convert array into string
Scanner s = new Scanner(System.in); //creating object of Scanner
System.out.println("Elements enter ::"); //print message
int e = s.nextInt();
System.out.println("Elements are :: "+ar[e]); //print array
}
}
Output:
Array are::
[8, 6, 7, 0, 2, 23, 7]
Elements enters ::

A small business named Widgets, Inc. has hired you to evaluate their wireless network security practices. As you analyze their facility, you note the following using a wireless network locator device:
a) They use an 802.11n wireless
b) The wireless network is broadcasting an SSID of Linksys.
c) The wireless network uses WPA2 with AES security.
d) Directional access points are positioned around the periphery of the building.
Based on this information what should you recommend your client do to increase their wireless network security?
Answer:
disable SSID broadcast and change the network name
Explanation:
Based on my experience with information technology and wireless networks my recommendation would be to disable SSID broadcast and change the network name. Disabling SSID will prevent the network name from appearing on devices that are searching for a network to connect to, and by changing the name it will also prevent anyone who knows the previous name from connecting unless they know the new name. Both of which will drastically increase security.
Final answer:
To enhance Widgets, Inc.'s wireless network security, it is recommended to change the SSID, disable SSID broadcast, and implement MAC Address Filtering.
Explanation:
To increase the wireless network security for Widgets, Inc., I would recommend the following steps:
Change the SSID: Broadcasting the manufacturer's default SSID makes it easier for attackers to identify the network. Changing it to a unique name enhances security.Disable SSID Broadcast: Disabling SSID broadcasting adds an extra layer of security as the network won't be openly visible to unauthorized users.Implement MAC Address Filtering: By configuring the wireless access point to only allow specific MAC addresses, you restrict unauthorized devices from connecting to the network.You are designing a wireless network for a client. Your client needs the network to support a data rate of at least 54Mbps. In addition, the client already has a wireless telephone system installed that operates 2.4GHz. Which 802.11 stand will work best in this situation?
Answer:
The best choice is 802.11a.
Explanation:
The most common option, that is widely used in home internet is 802.11b, however, this only supports a max speed of 11Mbps.
802.11a supports up to 54Mbps and it has regulated frequencies that prevent interference from other devices, such as the wireless system that your client already has. This option is more expensive, and its signal has issues going through walls and rooms but still, it is the one that fits him the most.
A variable declared to be of one class can later reference an extended class of that class. This variable is known as_________.
a. public
b. derivable
c. cloneable
d. polymorphic
e. none of the above, a variable declared to be of one class can never reference any other type of class, even an extended class
Answer:
Option (D) i.e., polymorphic is the correct answer to the following.
Explanation:
Because polymorphism is the concept of the Object-Oriented Programming in which an object or method having same in name.
Polymorphism is one of the essential features of the OOPs in which the method having the same name but different in their argument or the parameter list, in other words, the items having the same names but different in their working.
The variables declared.
A variable is a symbol and a placeholder for a quantity that may be changed. It may also include a number of vectors and a matrix and a function. They also refer to the set of elements of a function. They can be declared in one class and can be later used for reference to an extended class of the class.
Thus answer is the polymorphic variable. Can be declared in one class and never in another type of class.
The polymorphic includes one or more variants of the specific DNA sequence. the variables Polymorphisms can be sued to explain the strength and with variables and these are much larger in size.
