Explain the application software and utility software in detail

Vikentia [17]

Utility software is software designed to help analyze, configure, optimize or maintain a computer. It is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users.

In information technology, an application (app), application program or application software is a computer program designed to help people perform an activity. Depending on the activity for which it was designed, an application can manipulate text, numbers, audio, graphics, and a combination of these elements.

Create a Flash Card class. Flash Cards have a Question and an Answer, each of which are Strings. Your class should include a con

xeze [42]

Answer:

<u> FlashCard.java</u>

public class FlashCard {
String Question;
String Answer;
public FlashCard(String q, String a){
this.Question = q;
this.Answer = a;
}
public String toString(){
String output = "";
output += "Question: " + this.Question + "\n";
output += "Answer: " + this.Answer;
return output;
}
public boolean equals(String response){
if(this.Answer.equals(response)){
return true;
}
else{
return false;
}
}
}

public class Main {
public static void main(String[] args) {
FlashCard card1 = new FlashCard("What is highest mountain?", "Everest");
FlashCard card2 = new FlashCard("What is natural satelite of earth?", "Moon");
FlashCard card3 = new FlashCard("Who is the first president of US?", "George Washington");
FlashCard cards [] = {card1, card2, card3};
for(int i=0; i < cards.length; i++){
System.out.println(cards[i]);
}
}
}

Explanation:

In FlashCard.java, we create a FlashCard class with two instance variable, Question and Answer (Line 2 - 3). There is a constructor that takes two input strings to initialize the Question and Answer instance variables (Line 5-8). There is also a toString method that will return the predefined output string of question answer (Line 10 - 15). And also another equals method that will take an input string and check against with the Answer using string equals method. If matched, return True (Line 17 -24).

In Main.java, create three FlashCard object (Line 3-5) and then put them into an array (Line 6). Use a for loop to print the object (Line 8-10). The sample output is as follows:

Question: What is highest mountain?

Answer: Everest

Question: What is natural satelite of earth?

Answer: Moon

Question: Who is the first president of US?

Answer: George Washington

A web application that is designed as a single piece of software with multiple features that are fully integrated into the main

Nookie1986 [14]

Answer:

c. Service oriented architecture (SOA)

Explanation:

In a service oriented architecture (SOA), a component of an application provides services to other components of the application or other applications majorly via a communications protocol over a network. In other words, SOA is a programming or software development technique in which services communicate with each other across different platforms.

One key principle of SOA is to design an application (which in itself is a piece of software with multiple features) that is independent of any product, service, vendor or technology but can be integrated into other applications. SOA makes use of loose coupling - a technique in which a client service remains independent of another service that requires it.

In contrast, a monolithic architecture aims at developing a software that is self-contained, independent and not to be integrated into other applications.

On another hand, Software as a service (SaaS), though a bit similar to SOA, is a model in which an application is made available to customers basically through a network. Users basically access the application via a browser.

Therefore, the best option is

C. Service oriented architecture.

Which of the following is the safest authentication method?

myrzilka [38]

The safest authentication method is authentication using a smart card.

Smart Card Authentication uses a physical card along with a smart card reader and software on the workstation to validate users into enterprise resources like workstations and applications. Although smart card authentication offers a terrible user experience and is expensive to deploy and maintain, it is very secure.

Because smart card authentication requires a physical credential, a hardware card reader, and software, it is expensive and difficult to administer. Smart cards are only used in the most secure workplaces, such as three-letter agencies of the federal government or privileged access at a financial institution, as these environments frequently forbid employees from carrying smartphones to and from work.

1.What is a project methodology?

blagie [28]

Explanation:

1. Let’s suppose that we want to test a scientific hypothesis. What we need to do first is to come up with steps and techniques for testing this hypothesis. This, in a similar way explains what project methodologies are. A project methodology gives us a properly organized way of planning and executing a substantial amount of work that needs to be completed in a given amount of time. Think of it as a game plan that you need to up with to develop a product or an IS.

2. Following a particular methodology comes with its own advantages.

1. It gets you focused on the product you are trying to come up with.
2. So many lessons will be learnt and will be documented as experiences and will be integrated as best practice. In the event that the project is a success, the same methodology can be used once again in the future.
3. Saves time since the same prescription of tools, phases, and techniques used for a particular project can be reused once more to come up with another project.

3. It maps out the existence of a project from start to finish. It is defined within a given methodology. Projects, like humans, have defined life-cycles. The same way we come out of wombs, grow, mature, decline, and then die is the same way a project has a beginning, mid, and end.

4. It does not matter whether a project one is working on is huge or not, they have to be organized into a sequence of phases for manageability. These phases include phase exits, stage gates, and kill points. Having these phases aligned together will give an organization a clear indication of how to evaluate the project’s performance and be able to mitigate problems that arise.

5. Starting the next phase just before the current one ends can sometimes be a good thing since it can reduce the schedule of the project. This is what is known as fast tracking. It is a good idea but introducing one phase before another one ends can cause an overlap and as a result can pose as a risk. Do it if the risks are within scope and can be accepted.

6. An idea that someone comes up with to build a new information system or product can be counted as one of the initiation processes of a PLC. However, the first process is to define the goal of the project. Organizations have put amounts of time and investments into coming up with a project. Therefore, every little aspect of the project should be properly envisioned to meet the business's value. This is phase where we should ask ourselves questions like whether the project is going to be successful and how we will identify its success in correlation to the investments raised by the stakeholders. It is the phase upon which every detail is looked into carefully and goals defined before the project is flagged off.

7. This phase provides the direction and planning for the project. Once the project has been flagged off and is ready to move forward, the team needs to define what the objectives will be, when and what time the project will be completed, and the amount of money that will be required to finish. In addition, things like how many people are we looking at to complete the project and the technology that will be used to build the project are highly considered and looked into in this phase.

8. At this point, the project must be approved first before moving on to this phase. The teams put all efforts of design, development, and delivery of the final product. Whoever has invested on the product will now start to have a clear picture of everything that is going on from the first phase of planning to the actual implementation based on time it has taken to the budget that has been so far.

9. Every beginning must always have an end and this is the phase that ensures a well-defined end. It ensures that the amount of effort and work that the teams have put in developing and implementing the product is complete. This phase also sees the team and stakeholders have meetings to try and consolidate and come into terms of whether or not the goals of the planning phase have been achieved.

10. Because every single project has its own goals and achievements that it wants to meet. Every product is unique in terms of what it wants to achieve and the principles and practices might not work for every project. It is the processes used to come up with the particular project that will play an integral part in the life cycle
