Ques:- What is the use of the debugger in ABAP development
Right Answer:
The debugger in ABAP development is used to analyze and troubleshoot ABAP programs by allowing developers to pause execution, inspect variable values, step through code line by line, and identify errors or issues in the logic.
Ques:- How is error handling managed within RTE
Right Answer:
Error handling in the RTE (Runtime Environment) is managed through the use of error detection mechanisms, such as error hooks and status codes. The RTE provides interfaces for reporting errors, which can be handled by the application software components or the underlying operating system. Additionally, the RTE can log errors and trigger appropriate responses based on the severity of the error, ensuring that the system can recover or safely shut down if necessary.

It provides a graphical interface for creating graphs, configuring components, and managing metadata, enabling developers to build ETL processes efficiently.
Ques:- What is an ABAP data type and how is it declared
Right Answer:
An ABAP data type defines the kind of data a variable can hold, such as integer, string, or date. It is declared using the `DATA` statement, for example: `DATA: my_variable TYPE i.` (where `i` stands for integer).

Ques:- What is the difference between inline inline block and block elements
Right Answer:
Block elements take up the full width available and start on a new line (e.g., `<div>`, `<h1>`). Inline elements only take up as much width as necessary and do not start on a new line (e.g., `<span>`, `<a>`). Inline-block elements are similar to inline elements but can have width and height set, and they respect margins and padding (e.g., `<img>`, `<button>`).
Ques:- What is the difference between class and ID in CSS
Right Answer:
In CSS, a class is defined with a dot (.) and can be applied to multiple elements, while an ID is defined with a hash (#) and should be unique to a single element on a page.
Ques:- What is AJAX and how does it work
Right Answer:
AJAX (Asynchronous JavaScript and XML) is a web development technique that allows web pages to communicate with a server and update content asynchronously without reloading the entire page. It works by using JavaScript to send requests to the server, which can return data (often in JSON or XML format) that the browser can then use to update the webpage dynamically.
Ques:- How does a web server handle an HTTP request
Right Answer:
A web server handles an HTTP request by following these steps:

1. **Receive Request**: The server listens for incoming HTTP requests on a specific port (usually port 80 for HTTP or port 443 for HTTPS).
2. **Parse Request**: It parses the request to extract the method (GET, POST, etc.), URL, headers, and body.
3. **Process Request**: The server determines how to respond based on the request. This may involve retrieving files, querying a database, or executing server-side scripts.
4. **Generate Response**: It creates an HTTP response, which includes a status code (like 200 for success), headers, and the requested content (like HTML, JSON, etc.).
5. **Send Response**: The server sends the response back to the client (usually a web browser) over the network.
6. **Log Request**: Optionally, the server logs the request details for monitoring and analysis.
Ques:- What is the DOM and how do you manipulate it
Right Answer:
The DOM (Document Object Model) is a programming interface for web documents that represents the structure of a webpage as a tree of objects. You can manipulate the DOM using JavaScript by selecting elements (e.g., using `document.getElementById`, `document.querySelector`), modifying their properties (e.g., `element.innerHTML`, `element.style`), adding or removing elements (e.g., `element.appendChild`, `element.remove`), and responding to events (e.g., `element.addEventListener`).
