FTP is an unusual service in that it utilizes two ports, a 'data' port and a 'command' port. Traditionally these are port 21 for the command port and port 20 for the data port.

The confusion begins however, when we find that depending on the mode, the data port is not always on port 20. The File Transfer Protocol (FTP) is a standard network protocol that is used to transfer files between computers. To download or upload files, a user uses an FTP client to connect to an FTP server. In Active mode, the server assigns a port and the IP address will be the same as the FTP client making the request. In other words, Passive mode lets the client dictate the port used, and active mode lets the server set the port. 1.

Option B is correct When the application runs, a runtime error called division by zero is detected.

We may utilize exception handling to gently override such actions. Dividing an integer by zero is a mathematical mistake (not defined). If you develop a program without employing exception handling, the result of dividing by zero will be shown as infinity and cannot be processed further. When an integer is divided by 0, Python's built-in ZeroDivisionError exception is raised. The second parameter of a division or modulo operation will raise an exception if it is zero, according to this. A syntax mistake is an improper usage of the language itself that is detected by the compiler or interpreter. For instance, the Python syntax for is incorrect.

Answer:

E. Human judgment may be required for individual cases to deal with missing values in records used for building prediction models.

Explanation:

Data mining is the process of discovering patterns and trends in large data sets, typically with the goal of predicting future outcomes or identifying important relationships within the data.

There are two main types of data mining: supervised learning and unsupervised learning. In supervised learning, the data are labeled with the correct outcomes, and the algorithm is trained to predict those outcomes based on the input data. In unsupervised learning, the data are not labeled, and the algorithm must discover patterns and relationships within the data without guidance.

One common technique used in data mining is logistic regression, which is appropriate for predicting a binary outcome (e.g., yes/no, pass/fail). This technique is not appropriate for predicting continuous variables, so statement A is incorrect.

Supervised learning is not necessarily less profitable than unsupervised learning. In fact, many data mining applications use supervised learning because it allows for more accurate predictions. Therefore, statement B is incorrect.

Unsupervised learning algorithms do not predict or classify one and only one outcome variable at a time. They are capable of discovering multiple patterns and relationships within the data, so statement C is incorrect.

The more variables included in a model, the greater the risk of overfitting the data. Overfitting occurs when a model is overly complex and captures too much of the random noise in the data, leading to poor generalization to new data. Therefore, statement D is incorrect.

In data mining, it is common to encounter missing values in records. In such cases, human judgment may be required to decide how to handle the missing values in order to build accurate prediction models. Therefore, statement E is correct.

A specific place in memory is assigned to a variable when it is declared so that it can store a value. Special variables called pointers are used to store double value to other variables' memory addresses.

In C++, a pointer is a variable that holds the address (or location in memory) of another variable. In other words, a pointer directs the user to the location of a different variable. Pointers in C++ have data types just like ordinary variables do. The data type of the a pointer and the variable it points to should match.

We specify the data type of pointers so that we can determine how many bytes of data the variable it contains the address of uses. When we increase (decrease) the value of a pointer, By the size of the data type it points to, the pointer is increased (or decreased).

To use pointers in C++, we must take the following actions:

Make a pointer variable first.  Use the & operator to provide the pointer the address of another variable. Use the operator to access the value at the address.

main ()

{

 Var = 10;

       // Pointer level-1

Integer* ptr1;

// Pointer level-2

 ptr2;

// Pointer level-3

ptr3;

// Storing address of variable Var

// to pointer variable ptr1

ptr1 = &Var;

// Storing address of pointer variable

ptr2 = &ptr1;

// Storing address of level-2 pointer

ptr3 = &ptr2;

// Displaying values

print ("Value of variable "

 "Var = %d\n",

 Var);

print("Value of variable Var using"

 " Pointer ptr1 = %d\n",

 *ptr1);

print("Value of variable Var using"

 " Pointer ptr2 = %d\n",

 **ptr2);

print("Value of variable Var using"

 " Pointer ptr3 = %d\n",

Since the hypervisor, a component of virtualization, is in charge of managing all physical memory, it can make any memory pages left over in each guest virtual machine available to other virtual machines or the host computer.

A hypervisor is a class of computer software, firmware, or hardware that builds and manages virtual machines (also known as a virtual machine monitor, VMM, or virtualizer). A host machine is a computer on which a hypervisor is running one or more virtual machines, and a guest machine is a specific virtual machine. The hypervisor controls how the guest operating systems are executed and provides them with a virtual operating environment. The visitor often uses the native hardware to carry out instructions, unlike an emulator. The virtualized hardware resources may be shared by several instances of various operating systems. For instance, Linux, Windows, and macOS instances can all operate on a single real x86 computer. Contrastingly, with operating-system-level virtualization, each instance (often referred to as a container) only needs to share a single kernel, while the guest operating systems—such as various Linux distributions using the same kernel—can differ in user space.

Customers of cloud computing have been pushed to use private clouds due to the numerous legal and regulatory barriers to cloud computing, which are frequently connected to international data access and transport. It is often more costly and provides less advantages.

A private cloud can be hosted on-premises (on hardware operating in a datacenter owned by the firm) or at a datacenter owned and operated by a third party on the customer's behalf. On-premise vs. third-party data centers have highly distinct operating costs and responsibility structures, as you might expect. The emphasis is usually on how services are made available to a particular firm, providing only authorized users logical and/or physical access.
