Explanation:

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

On the other hand, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.

Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.

Hence, in cybersecurity the use of encryption and authentication protocols is the standard method of countering attempts to alter or insert transmissions.

Explanation:

Write a program that contains the following two methods:

/** Convert from feet to meters */

public static double footToMeter(double foot)

/** Convert from meters to feet */

public static double meterToFoot(double meter)

The formula for the conversion is: meter = 0.305 * foot and foot = 3.279 * meter Write a test program that invokes these methods. PLEASE WRITE IN JAVA.

//Declare the class

public class Converter{

    //method footToMeter that receives the foot as parameter

    public static double footToMeter(double foot){

        //declare a double variable called meter,

        //to hold the result of the conversion

        double meter;

        //using the given formula, conver the foot to meter and

        //store the result in the meter variable

        meter = 0.305 * foot;

        //return the result stored in meter

        return meter;

    }

    //method meterToFoot that receives the meter as parameter

    public static double meterToFoot(double meter){

        //declare a double variable called foot,

        //to hold the result of the conversion

        double foot;

        //using the given formula, convert the meter to foot and

        //store the result in the foot variable.

        foot = 3.279 * meter;

        //return the result stored in foot.

        return foot;

    }

    //Test program to invoke those methods

    public static void main(String []args){

           //Convert 120 feet to meter

           System.out.println("120 feet to meter is " + footToMeter(120));

           //Convert 36 meters to foot

           System.out.println("36 meters to feet is " + meterToFoot(36));

    }

}  //End of class declaration

120 feet to meter is 36.6

36 meters to feet is 118.044

Goal-based decision making is goal generation together with goal-based planning

This decomposition of decision making in goal generation and planning raises several

questions, such as:

– How to represent beliefs? How to represent obligations? In this paper we represent

beliefs and obligations by rules, following the dominant tradition in deontic logic

(see e.g. [26,27]).

– How to develop a normative decision theory based on belief and obligation rules?

In this paper we introduce a qualitative decision theory, based on belief (B) and

obligation (O) rules.

c. Using public member functions to access and manipulate the data members

Explanation:

In object oriented programming, abstraction is used in order to lessen the complexity and hiding non essential details about how a program is actually working in the background. In order to achieve abstraction, classes are defined in such a way that the data members are hidden and the member functions form public interface. The public member functions here are used to access and manipulate these hidden or private data members. So the use of public member functions shows the abstraction here. These members functions are public so they can be directly accessed and the hidden or private data members can be accessed indirectly with the help of these member functions. So internal details of the classes and its data members are hidden from the outside world. Thus abstraction used here ensures security of data members of two classes and protects them from any accidental alterations by other parts of program.
