Consider the following class, which uses the instance variable balance to represent a bank account balance.
public class BankAccount {
private double balance;
public double deposit(double amount) {
/* missing code */
}
}
The deposit method is intended to increase the account balance by the deposit amount and then return the updated balance. Which of the following code segments should replace /* missing code */ so that the deposit method will work as intended?
a.
amount = balance + amount;
return amount;
b.
balance = amount;
return amount;
c.
balance = amount;
return balance;
d.
balance = amount;, , return balance;,
balance = balance + amount;
return amount;
e.
balance = balance + amount;
return balance;
Answer:
e.
balance = balance + amount;
return balance;
Explanation:
Required
Code to update account balance and return the updated balance
The code that does this task is (e).
Assume the following:
[tex]balance = 5000; amount = 2000;[/tex]
So, code (e) is as follows:
balance = balance + amount; [tex]\to[/tex]
[tex]balance = 5000 + 2000[/tex] [tex]\to[/tex]
[tex]balance = 7000[/tex]
Here, the updated value of balance is 7000
So: return balance

Discuss at least 1 Microsoft Windows security features that could protect data?
Answer:
Virus & threat protection.
Explanation:
Monitor threats to your device, run scans, and get updates to help detect the latest threats.
One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.
BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.
By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.
BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.
Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

A group of computer scientists wants to create a fixed-length compression algorithm. The simplest way to achieve compression is to use a fixed-length code generator. The idea behind this type of code generator is to assign a fixed-length bit sequence to each symbol of the alphabet. As part of this group of computer scientists, your goal is to write a program to determine the alphabet used by the message to be compressed (set of different characters in the input message), and the frequency of each symbol in the alphabet, using conditionals, loops, and arrays.
Answer:
Here the code is given as follows,

4. Interaction between seller and buyer is called___.
A. Demanding
B. Marketing
C. Transactions
D. Oppurtunity
Answer:
C. Transactions.
Explanation:
A transaction can be defined as a business process which typically involves the interchange of goods, financial assets, services and money between a seller and a buyer.
This ultimately implies that, any interaction between a seller and a buyer is called transactions.
For example, when a buyer (consumer) pays $5000 to purchase a brand new automobile from XYZ automobile and retail stores, this is referred to as a transaction.
Hence, a transaction is considered to have happened when it's measurable in terms of an amount of money (price) set by the seller.
Price can be defined as the amount of money that is required to be paid by a buyer (customer) to a seller (producer) in order to acquire goods and services. Thus, it refers to the amount of money a customer or consumer buying goods and services are willing to pay for the goods and services being offered. Also, the price of goods and services are primarily being set by the seller or service provider.

You are designing an application at work that transmits data records to another building in the same city. The data records are 500 bytes in length, and your application will send one record every 0.5 seconds
Is it more efficient to use a synchronous connection or an asynchronous connection? What speed transmission line is necessary to support either type of connection? Show all your work.
Solution :
It is given that an application is used to transmit a data record form one building to another building in the same city, The length of the data records is 500 bytes. and the speed is 0.5 second for each record.
a). So for this application, it is recommended to use a synchronous connection between the two building for data transfer as the rate data transfer is high and it will require a master configuration between the two.
b). In a synchronous connection, 500 bytes of data can be sent in a time of 0.5 sec for each data transfer. So for this the line of transmission can be either wired or wireless.

The program in python is as follows:
n = int(input("n: "))
sum = 0
for i in range(2,n+1):
if i%2 == 0:
sum+=i
print(sum)
Explanation:
This gets input n
n = int(input("n: "))
This initializes sum to 0
sum = 0
This iterates through n
for i in range(2,n+1):
This checks if current digit is even
if i%2 == 0:
If yes, take the sum of the digit

Write a program Ticket.py that will allow the user to enter actual speed
limit, the speed limit at which the offender was travelling, and the number
of previous tickets that person has received. The application should
calculate and display how many miles over the speed limit the offender
was travelling, the cost of the speeding ticket, and court cost. Use $10.00
as the amount to be charged for each mile per hour over the speed limit.
The court cost should be $50.00
Answer:
Following are the code to the given question:
def speedlimit():#defining a method speedlimit
a= int(input("Enter the offender's speed in mph: "))#defining a variable for input value
lim = int(input("Enter the speed limit in mph: "))#defining a variable for input value
n = int(input("The number of previous tickets that person has received: "))#defining a variable for input value
if (lim >= 20) and (lim < 70):#defining if block to check speed is between 20 to 70
if a > lim:#use if to check lim value greater than a
print("Driver was going", a-lim, "mph over the limit.")#print calculated value with message
print("The cost of the speeding ticket $",10*(a-lim))#print calculated value with message
else:
print( "Driver was going at a legal speed.")#print message
else:
print('Invalid speed limit.')#print calculated value with message
print("Court cost $",(50 + n*20))#print calculated value with message
speedlimit()
Output:
Please find the attached file.
Explanation:
In this code, a method "speedlimit" is declared that defines three variables that are "a, lim, and n" in which we input value from the user-end.
Inside the method, a nested conditional statement is used that checks the speed value is between 20 to 70 if it is true it will go to the next condition in which it checks lim value greater than a. It will use a print message that will print the calculated value with the message.
Suppose that in a 00-11 knapsack problem, the order of the items when sorted by increasing weight is the same as their order when sorted by decreasing value. Give an efficient algorithm to find an optimal solution to this variant of the knapsack problem, and argue that your algorithm is correct.
Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.
