Referencial Integrity Contraint

Explanation:

The referential integrity constraint states that the customer ID i.e (CustID) in the Order table must match a valid CustID in the Customer table. Most relational databases have declarative referential integrity. That is to say, when the tables are created the referential integrity constraints are set up so as to maintain the quality of information.

B) machine-to-machine (M2M) communications

Explanation:

Manufacturing technology refers to the technological advancement that enables the production of the tools that further helps in the manufacturing of the other goods. The quality, quantity, and production are enhanced with these manufacturing technologies. Machine-to-machine communications are designed for manufacturing technologies. In this technology, the information and data can be easily transferred from one device to another either by the help of wires or without wires.

The technology designed for use in manufacturing among the options listed is machine-to-machine (M2M) communications.

Machine-to-machine (M2M) communications involve the exchange of data or information between devices or machines without human intervention.

In the context of manufacturing, M2M technology can be used to connect and communicate between various machines, equipment, sensors, and systems involved in the manufacturing process.

This allows for automation, real-time monitoring, data collection, and coordination, ultimately improving efficiency and productivity in manufacturing operations.

D. Network tap

Explanation:

A network tap is a hardware device that provides a way to access the data flow across a computer network.

A sniffer is either hardware or software that provides a way to access the data flow across a computer network.

Hence, these two IDS components are very similar.

Cheers.

A network tap is the same as a sniffer in that it runs in conjunction with a network card in promiscuous mode. Therefore, option D is correct.

What is network tap?

A network tap can be described as a system that monitors events on a local network. A tap is a dedicated hardware device, which offers a way to access the data flowing across a network.

The network tap has three ports which are an A port, a B port, and a monitor port. A tap inserted between A and B passes all traffic via unimpeded in real-time, but copies that same data to its monitor port, enabling a third party.

Network taps are generally used for network intrusion detection systems, network probes, packet sniffers, RMON probes, and other monitoring and collection devices and software that need access to a network segment.

Taps are utilized in security applications because they are non-obtrusive, are not detectable on the network, and will pass through or bypass traffic even if the tap stops working.

Answer:

Goals help provide our everyday lives with structure, and operate similarly at the institutional level, offering organizations a low cost method of encouraging motivation, communication and accountability. In short, goals help organizations to achieve a variety of ends—including the reduction of energy waste.

Energy efficiency improvement goals, also known as energy efficiency targets, are intended reductions in energy over a specified time frame that have been defined in a SMART manner. Targets are useful because they can encourage decision makers to improve the use of energy in their communities and operations. Moreover, energy efficiency targets can have short or long term timeframes and can be implemented on various scales, ranging from the national level down to individual buildings. Cities should explore both mandatory public sector targets and voluntary private sector targets to forge energy-efficient communities.

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.

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.

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
