A small company with 100 computers has hired you to install a local area network. All fo the users perform functions like email, browsing and Office software. In addition, 25 of them also do a large number of client/server requests into a database system. Which local area network operating system would you recommend?

Explanation:

Concurrency Control in Database Management System is a procedure of managing simultaneous operations without conflicting with each other. It ensures that Database transactions are performed concurrently and accurately to produce correct results without violating data integrity of the respective Database.And The ACID properties, in totality, provide a mechanism to ensure correctness and consistency of a database in a way such that each transaction is a group of operations that acts a single unit, produces consistent results, acts in isolation from other operations and updates that it makes are durably stored.

Answer:

The answer is "False"

Explanation:

It is put to use Six Sigma had 3.4 defects per million opportunities (DPMO) from the start, allowing for a 1.5-sigma process shift. However, the definition of zero faults is a little hazy. Perhaps the area beyond 3.4 DPMO is referred to by the term "zero faults.", that's why Before being released, large computer programs, such as operating systems, must have no faults the wrong choice.

A Java program that reads a list of integers and outputs them in reverse is written as,

import java.util.Scanner;

public class ReverseList {

   public static void main(String[] args) {

       Scanner scnr = new Scanner(System.in);

       // Read the number of integers

       int numIntegers = scnr.nextInt();

       // Create an array to store the integers

       int[] integers = new int[numIntegers];

       // Read the integers into the array

       for (int i = 0; i < numIntegers; i++) {

           integers[i] = scnr.nextInt();

       }

       // Output the integers in reverse order

       for (int i = numIntegers - 1; i >= 0; i--) {

           System.out.print(integers[i]);

           // Add comma unless it's the last integer

           if (i > 0) {

               System.out.print(",");

           }

       }

       System.out.println(); // Add a new line at the end

   }

}

Given that,

Write a Java program that reads a list of integers and outputs those integers in reverse.

Here, The input begins with an integer indicating the number of integers that follow.

For coding simplicity, follow each output integer by a comma, including the last one.

So, A Java program that reads a list of integers and outputs them in reverse:

import java.util.Scanner;

public class ReverseList {

   public static void main(String[] args) {

       Scanner scnr = new Scanner(System.in);

       // Read the number of integers

       int numIntegers = scnr.nextInt();

       // Create an array to store the integers

       int[] integers = new int[numIntegers];

       // Read the integers into the array

       for (int i = 0; i < numIntegers; i++) {

           integers[i] = scnr.nextInt();

       }

       // Output the integers in reverse order

       for (int i = numIntegers - 1; i >= 0; i--) {

           System.out.print(integers[i]);

           // Add comma unless it's the last integer

           if (i > 0) {

               System.out.print(",");

           }

       }

       System.out.println(); // Add a new line at the end

   }

}

Answer:

b. The constructor for the parent class is called.

Explanation:

In this case this specific piece of code is calling the constructor for the parent class. Since a MountainBike object is being created. This creation uses the MountainBike class constructor but since this is a subclass of the Bicycle class, the super() method is calling the parent class constructor and passing the variables startCadence, startSpeed, startGear to that constructor. The Bicycle constructor is the one being called by super() and it will handle what to do with the variables inputs being passed.

Answer:

When implementing a 1:1 relationship, the foreign key should be placed on the optional side if one side is mandatory and one side is optional.  

When this is implemented, the foreign key should be made mandatory.

Explanation:

A foreign key (FK) is a primary key (PK) in relational databases.  It is used to establish a relationship with a table that has the same attribute with another table in the database.  A mandatory relationship exists when the foreign key depends on the parent (primary key) and cannot exist without the parent.  A one-to-one relationship exists when one row in a data table may be linked with only one row in another data table.

Answer:

Unification may be a process by which two logical individual atomic expressions, identical by replacing with a correct substitution. within the unification process, two literals are taken as input and made identical using the substitution process. There are some rules of substitution that has got to be kept in mind:

The predicate symbol must be an equivalent for substitution to require place.

The number of arguments that are present in both expressions must be equivalent.

Two similar variables can't be present within the same expression

Explanation:

a. American (Bob), American (y):-

In this scenario, Unification is feasible consistent with the principle. The substitution list is going to be [y/Bob].

b. Enemy (Nono, America), Enemy(x,y):-

In this scenario, the Unification is feasible consistent with the principles. The substitution list is going to be [x/Nono, y/America].

c. Weapon (Missile), soldTo (Missile, y), Weapon (x), soldTo (x, Nono):-

In this scenario, the Unification isn't possible because the predicate is different i.e. Weapon and soldTo.

d. L(x, y), (L(y, x) ^ L(A, B)):-

In this scenario, Unification isn't possible because the number of arguments is different within the given expression

The following is written in Java. It uses File input, to get the file and read every line in the file. It adds all the lines into a variable called fullString. Then it uses regex to split the string into separate words. Finally, it maps the words into an array that counts all the words and how many times they appear. A test case has been created and the output can be seen in the attached image below. Due to technical difficulties I have added the code as a txt file below.

Answer:

D. MAN

Explanation:

A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a switch, a router, printer, etc.

On the other hand, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.

Basically, a metropolitan area network (MAN) spans across a geographic area such as a city and it's larger than a local area network (LAN) but significantly smaller than a wide area network (WAN).

In conclusion, the network type that the patrol services of a city's police department would most likely use is a metropolitan area network (MAN).

Answer:

The correct answer is D. Man.

Answer:

C. Spoofing.

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.

Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.

Basically, the computer of an attacker or a hacker assumes false internet address during a spoofing attack so as to gain an unauthorized access to a network.

Filmmaking involves a number of complex and discrete stages including an initial story, idea, or commission, through screenwriting, casting, shooting, sound recording and pre-production, editing, and screening the finished product before an audience that may result in a film release and an exhibition.

Answer:

The answer is "MPLS".

Explanation:

The MPLS stands for Multiprotocol Label Switching. This packet switching method facilitates the generation of easier personal backbones using a less physical channel, which sends information from one source to its destination with labels rather than IP addresses. Many of these WAN services are sold through huge companies. It is also a technology for data transfer that boosts speed and regulates network traffic flow. The information is directed with this technology via a label rather than needing complicated surveys at every stop in a route cache.

The answer is "Developing the custom control for the user interface"

Explanation:

The major difference between customized control & user control would be that it inherit throughout the inheritance tree at different levels. Usually, a custom power comes from the system. Windows. UserControl is a system inheritance.

Using accuracy up is the major reason for designing a custom UI control. Developers must know how to use the API alone without reading the code for your component. All public methods and features of a custom control will be included in your API.

Answer:

Hence the answer is given as follows,

Explanation:

Base Case:-  

If (num == 0) //This is the base case for the given recursive method  

return 1;  

If(num % 2!=0) checks whether num is odd.  

The above condition is true for all odd numbers and false for even numbers.  

if the remainder is not equal to zero when we divide the number with 2 then it is odd.  

The method:-  

The above recursive method calculates the product of odd numbers up to the given range(that is num)  

For num=5   => 15(5*3*1).  

For num=7   => 105(7*5*3*1).  

For num=10 => 945(9*7*5*3*1).

Answer:

a. Determine your needs

b. make the Assessments of  the resources available to you,

c. do a ranking of the resources in order of their usefulness to you,

d. create or allow the time to make use of the resources.

Explanation:

technology strategy is a concept that gives the important elements of a department and how these elements can interact with each other in order to get the continuous value.

The correct order is to first determine what your needs are, then you carry out an assessment of all the resources that you have at your disposal, then you rank these resources from the most useful to the least and the last is for you to create the time that you would have to use these resources.

Explanation:

The UML scheme is a UML-based diagram intended to depict the system visually, together with its key actors, roles, activities, objects, and classes, to gather information the about system, change that, or maintain it.

Every complex process is better understood via sketches or pictures. These diagrams have a higher understanding effect. By glancing about, we notice that diagrams are not a new idea but are widely used in various business types. To enhance understanding of the system, we prepare UML diagrams. There is not enough of a single diagram to represent all aspects of the system. You can also create customized diagrams to satisfy your needs. Iterative and incremental diagrams are usually done.

There are two broad diagram categories and that they are broken into subclasses again:

The function strpos() is a function in php that returns the position of the first occurrence of a particular substring in a string. Positions are counted from 0. The function receives two arguments. The first argument is the string from which the occurrence is to be checked. The second argument is the substring to be checked.

In this case, the string is "Get Well Soon!" while the substring is "Well"

Starting from 0, the substring "Well" can be found to begin at position 4 of the string "Get Well Soon!".

Therefore, the function strpos("Get Well Soon!", "Well") will return 4.

Then, with the echo statement, which is used for printing, value 4 will be printed as output of the code.
