Jupiter Interview Questions and Answers
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 are event bubbling and event delegation in JavaScript
Right Answer:
Event bubbling is a JavaScript event propagation method where an event starts from the target element and bubbles up to its ancestors in the DOM hierarchy. Event delegation is a technique that involves attaching a single event listener to a parent element to manage events for multiple child elements, leveraging event bubbling to handle events efficiently.
Ques:- How does flexbox work in CSS
Right Answer:
Flexbox, or the Flexible Box Layout, is a CSS layout model that allows items in a container to be arranged and aligned efficiently. It works by defining a container as a flex container using `display: flex;`, which enables its direct children (flex items) to be laid out along a main axis (horizontal or vertical). You can control the alignment, direction, spacing, and size of these items using properties like `flex-direction`, `justify-content`, `align-items`, and `flex-wrap`. This makes it easier to create responsive layouts without using floats or positioning.
Ques:- What are cookies sessions and local storage in web development
Right Answer:
Cookies are small pieces of data stored on the user's computer by the web browser while browsing a website, used for tracking and remembering information about the user. Sessions are temporary storage on the server that keeps track of user data across multiple requests during a single visit, typically expiring when the user closes the browser. Local storage is a web storage feature that allows websites to store data in the user's browser persistently, even after the browser is closed, with no expiration time.
Ques:- What is the difference between frontend and backend development
Right Answer:
Frontend development refers to the part of a website or application that users interact with directly, including the layout, design, and user interface. Backend development involves the server-side, focusing on databases, server logic, and application functionality that users do not see.

Ques:- How do you prioritize tasks when everything seems urgent and subject to change
Right Answer:

I focus on completing tasks in the first two categories first. I also stay flexible and regularly reassess priorities as new information comes in or situations change.
Ques:- What is your hobby and how you deal with work pressure in target timing?
