I hope this helps!

To modify a program is to rewrite the program in another way.

In order to make the program an interactive program, we have to remove the following program statement:

final int QUARTS_IN_GALLON=4;

The above program statement assigns 4 to the variable QUARTS_IN_GALLON.

This means that:

Each time the program is run, the value of QUARTS_IN_GALLON is always 4.

Next, we replace the statement with:

Scanner input = new Scanner(System.in)

int QUARTS_IN_GALLON;

QUARTS_IN_GALLON = input.nextInt();

So, the complete modified program is:

class QuartsToGallonsInteractive{

public static void main(String[] args){

Scanner input = new Scanner(System.in)

int QUARTS_IN_GALLON;

QUARTS_IN_GALLON = input.nextInt();

int quartsNeeded=18;

int gallonsNeeded; int extraQuartsNeeded; gallonsNeeded=quartsNeeded/QUARTS_IN_GALLON; extraQuartsNeeded=quartsNeeded%QUARTS_IN_GALLON;

System.out.println("A job that needs " + quartsNeeded + " quarts requires " + gallonsNeeded + " gallons plus " + extraQuartsNeeded + " quarts");

}

ISA stands for International Standards on Auditing. These standards are a set of globally recognized audit guidelines developed by the International Auditing and Assurance Standards Board (IAASB).

These standards aid in the achievement of international consistency and quality in auditing practices and provide for an objective methodology that auditors can use to measure the effectiveness of the audit process. It is relevant for both internal and external auditing.Internal auditors are in charge of verifying a company's accounts, processes, and systems. An internal auditor's function is to ensure that a company's financial data is correct, secure, and that all procedures are followed. Internal auditors should be familiar with ISA and use it to help guide their work.External auditors, on the other hand, are auditors who are not employed by the company they are auditing. External auditors must follow all ISA principles and guidelines to perform a fair and objective audit of a company's financial statements. External auditors are obliged to follow the auditing regulations and procedures of any regulatory body in addition to following ISA guidelines, as the auditing process is overseen by a number of regulatory bodies.In conclusion, the ISA provides guidelines that both internal and external auditors must follow. External auditors are required to comply with all ISA principles, regulations, and procedures in addition to the auditing guidelines of regulatory bodies.

Virtualization: It is a strategy of creating several instances of operating systems or applications that execute on a single computer or server. Virtualization employs software to reproduce physical hardware and create virtual versions of computers, servers, storage, and network devices. As a result, these virtual resources can operate independently or concurrently.

Type 2 Hypervisors: Type 2 hypervisors are hosted hypervisors that are installed on top of a pre-existing host operating system. Because of their operation, Type 2 hypervisors are often referred to as "hosted" hypervisors. Type 2 hypervisors offer a simple method of getting started with virtualization. However, Type 2 hypervisors have some limitations, like the fact that they are entirely reliant on the host operating system's performance.

"Hosted" Approach: The hosted approach entails installing a hypervisor on top of a host operating system. This hypervisor uses hardware emulation to create a completely functional computer environment on which several operating systems and applications can run concurrently. In general, the hosted approach is used for client-side virtualization. This method is easy to use and is especially useful for the creation of virtual desktops or the ability to run many operating systems on a single computer.

A hypervisor is software that creates and runs VM instances: A hypervisor, also known as a virtual machine manager, is software that creates and manages virtual machines (VMs). The hypervisor allows several VMs to execute on a single physical computer, which means that the computer's hardware can be utilized more efficiently. The hypervisor's role is to manage VM access to physical resources such as CPU, memory, and I/O devices, as well as to provide VM isolation.

def update_data():

   rec = {}

   fin = open("record.dat", "rb")

   fout = open("updated_record.dat", "wb")  # Statement 2

   found = False

   sid = int(input("Enter student id to update his marks :: "))

   while True:

       try:

       print("The marks of studentid ", sid, " has been updated.")

   else:

       print("No student with such id is found")

   fin.close()

   fout.close()

The explanation of the changes:

Statement 1: Added an import statement for the pickle module, which is required to read and write Python objects to binary files.

Statement 2: Opened a new file "updated_record.dat" in write binary mode to write the updated records to it.

Statement 3: Loaded the next record from the input file using pickle.load() method and stored it in the rec variable. This will read the binary data from the input file and convert it to a Python object.

Statement 4: Dumped the updated record to the output file using the pickle.dump() method. This will convert the Python object to binary data and write it to the output file.

Note that I also added a try-except block to catch the EOFError exception, which is raised by pickle.load() when there are no more objects to read from the file. Finally, I changed the output message in the last else block to indicate that no student with the given ID was found.

The idea that the whole address space can be considered as one single block, with each range of addresses as a sub-block, is referred to as "supernetting" or "classless inter-domain routing" (CIDR). If we accept this concept, sub-netting becomes more flexible and efficient as it allows for the allocation of variable-sized address blocks, enabling better address space utilization.

In traditional subnetting, IP addresses were divided into fixed-sized blocks, such as Class A, Class B, and Class C networks. This led to inefficient utilization of address space as organizations were assigned blocks larger than what they actually needed, resulting in address wastage.

With supernetting or CIDR, the address space is viewed as a single block, and addresses are allocated based on the actual requirements of each organization. Subnets can be created with varying sizes, allowing for more efficient utilization of addresses. This flexibility in address allocation leads to better management of IP addresses and helps address the issue of address exhaustion.

In summary, accepting the concept of considering the entire address space as one single block allows for supernetting or CIDR, which enhances the flexibility and efficiency of address allocation. It leads to better address space utilization and helps mitigate the problem of address exhaustion.
