The most pressing security risk in this scenario is (d) Confidentiality.

USB- A USB, or universal serial bus, is a type of hardware interface used to connect devices to computers. USB technology simplifies the process of connecting peripherals to computers by replacing a range of incompatible connectors with a single standardized plug and socket.

Security- Security is a procedure or system that is put in place to safeguard an organization, business, or individual from theft, destruction, or unauthorized access. Security is a set of measures and protocols that are designed to protect and secure an individual, organization, or business from harm, damage, or loss, as well as to provide a safe and secure environment for workers and customers. Security involves the use of technology, software, and hardware to secure digital and physical assets. Confidentiality, integrity, and availability are three principles of security.

Confidentiality- Confidentiality is the practice of keeping sensitive data, information, or communications private and secure. Confidentiality is critical in any business or organization, particularly when it comes to sensitive financial or personnel information. Confidentiality is one of the three cornerstones of security, and it helps to ensure that private information remains private.

In the scenario provided, a user copies files from her desktop computer to a USB flash drive and puts the drive in her pocket. The most pressing security risk is Confidentiality. Since the USB device is portable, it's simple for it to be lost, misplaced, or stolen, allowing any confidential data on it to be viewed by anyone who finds it. As a result, keeping sensitive information safe is critical.

Therefore, the correct answer is (d) confidentiality

Often, programmers list the constructor first because it is the first method used when an object is created.

A constructor is a unique method of the class that is executed when an instance of a class is created. It has the same name as the class and is created as a separate method. The constructor is also used to assign values to variables when the object is created. You can define constructors with or without parameters. The object's properties and variables can be initialized with the help of a constructor. Here's an example of how to create a constructor:

class Car {

String name;

int model_number;

For this question, you need to implement a simple linear regression from scratch without using a library. The linear equation that you need to use for this exercise is y=50x+22, which you will use to generate some synthetic data with random variation to make the problem interesting.

Lets discuss more in detail.

To begin, you need to randomly select 20 x values between 0 and 100 using a uniform distribution. To do this, you can use a for loop to iterate through the range of 0 to 100 and randomly select 20 x values.

Once you have your x values, you can then use the linear equation of y=50x+22 to calculate the corresponding y values. Finally, you can use these x and y values to create a linear regression and check if it rounds to the original equation.

Grading criteria: The result of your linear regression should round to the original equation. It is not expected to be perfect.
