This can improve performance and stability by preventing unexpected plan changes that could lead to slower query execution.

Web Development

Ques:- What are promises and async await in JavaScript

Asked In :- Unyscape Infocom Pvt. Ltd., Medvarsity Online, Ziffity Solutions, LiteBreeze Infotech, CakeSoft Technologies, Sun Technology Integrators, Happiest Minds Technologies Pvt., Ray Business Technologies, XIPHIAS Software Technologies, Spark Infosys,

Right Answer:
Promises in JavaScript are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value. They allow you to handle asynchronous code more easily by providing methods like `.then()` for success and `.catch()` for errors.

`async` and `await` are syntactic sugar built on top of promises. An `async` function always returns a promise, and within an `async` function, you can use `await` to pause execution until a promise is resolved, making the code easier to read and write as if it were synchronous.

Web Development

Ques:- What is the difference between HTML and HTML5

Asked In :- Vinove Software & Services Pvt Ltd, Hummingbird Web Solutions, Aakit Technologies, Namecheap Web Services, TNQ Technologies, Adnate IT Solutions, Spark Infosys, Keyideas Infotech, SysTrack Solution, CodeClouds IT Solutions,

Right Answer:
HTML5 is the latest version of HTML, which includes new features such as native support for audio and video, new semantic elements (like `<article>`, `<section>`, and `<header>`), improved parsing rules, and better support for web applications with APIs like local storage and canvas. HTML, on the other hand, refers to earlier versions that lack these enhancements.

Web Development

Ques:- How does a web server handle an HTTP request

Asked In :- Medvarsity Online, Queppelin Technology Solutions, Ziffity Solutions, Trigent Software, Itobuz Technologies, Namecheap Web Services, CakeSoft Technologies, QuickXpert Infotech, Webvillee Technology, Recodem,

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.

Web Development

Ques:- How does flexbox work in CSS

Asked In :- Trigent Software, Fortunesoft IT Innovations, Dhruvsoft Services, LiteBreeze Infotech, TRICON INFOTECH PVT, QuickXpert Infotech, Spectra Medix India, Webvillee Technology, Fission Infotech, Ray Business Technologies,

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.

Web Development

Ques:- What is the difference between inline inline block and block elements

Asked In :- Vinove Software & Services Pvt Ltd, Queppelin Technology Solutions, Walkover Web Solutions, CakeSoft Technologies, Recodem, Energytech Global, Incise Infotech, First Zen, Angular Minds, CIGNEX Datamatics Technologies,

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>`).
