AJAX involves web development techniques that engage web technologies on the client side so as to create asynchronous web applications. Web applications engage it in sending and retrieving data from a server.

Questions and Answers

1.

Using the AJAX, web applications can receive and send date asynchronously from a
- A.
  
  Database
- B.
  
  Server
- C.
  
  Control
- D.
  
  Store
Correct Answer
D. Store

Explanation
AJAX (Asynchronous JavaScript and XML) is a technique that allows web applications to send and receive data asynchronously, without the need to refresh the entire page. It enables the application to communicate with a server in the background, without interrupting the user's interaction with the page. In this context, the term "store" refers to a data storage location, such as a database or a server, where the web application can retrieve and store data. Therefore, the correct answer is "Store" as it encompasses both the database and server, which are common storage options for web applications using AJAX.

The technologies incorporated in AJAX are these except
- A.
  
  HTML and CSS
- B.
  
  Document object model
- C.
  
  JavaScript
- D.
  
  Product applications
Correct Answer
D. Product applications

Explanation
AJAX (Asynchronous JavaScript and XML) is a web development technique that combines HTML, CSS, JavaScript, and the Document Object Model (DOM) to create interactive and dynamic web applications. The technologies incorporated in AJAX are HTML, CSS, and JavaScript, as they are the essential components for building AJAX applications. However, "Product applications" is not a technology or component used in AJAX, making it the correct answer.

3.

With Ajax, which of these is no longer required for data manipulation?
- A.
  
  XML
- B.
  
  XSLT
- C.
  
  JSON
- D.
  
  HTML
Correct Answer
B. XSLT

Explanation
With Ajax, XSLT is no longer required for data manipulation. Ajax allows for asynchronous communication between the client and server, enabling the retrieval and manipulation of data without the need for a full page reload. JSON (JavaScript Object Notation) is commonly used as the data format in Ajax requests, as it is lightweight and easily readable by JavaScript. XML and XSLT, on the other hand, are not necessary for data manipulation with Ajax as JSON can handle the task more efficiently.

With Ajax, which of these is no longer required for data exchange ?
- A.
  
  XML
- B.
  
  XSLT
- C.
  
  HTML
- D.
  
  JSON
Correct Answer
A. XML

Explanation
With Ajax, XML is no longer required for data exchange. Ajax allows for asynchronous communication between the client and server, enabling data to be exchanged without requiring a full page reload. XML was commonly used for data exchange before Ajax, but with the advent of Ajax, other lightweight data formats like JSON have become more popular due to their simplicity and ease of use. JSON is now commonly used for data exchange in Ajax applications.

Correct Answer
B. JavaScript

Explanation
JavaScript brings AJAX technologies together. AJAX (Asynchronous JavaScript and XML) is a set of web development techniques that allows for the asynchronous exchange of data between a web browser and a web server. JavaScript is the primary language used to implement AJAX functionality on the client-side. It provides the ability to make asynchronous requests to the server, handle the response, and update the webpage dynamically without requiring a full page reload.

- A.
  
  Change content
- B.
  
  Reload at times
- C.

- D.
  
  Control other pages
Correct Answer
A. Change content

Explanation
AJAX stands for Asynchronous JavaScript and XML. It is a technology that allows web pages to update content dynamically without reloading the entire page. With AJAX, developers can send and receive data from a server in the background, enabling them to change the content of a web page without requiring a full page reload. This makes the user experience smoother and more interactive as it allows for real-time updates without interrupting the user's workflow. Therefore, the correct answer is "change content".

HTML is used to structure the content and provide meaning to the different elements on a webpage, while CSS is used to style and format those elements, making them visually appealing and organized. Together, HTML and CSS play a crucial role in creating visually appealing and well-structured web pages.
