Answer: Web Development is the process of building and maintaining websites. It includes everything from building simple static pages to complex web applications. Web development typically involves front-end development (user interface) and back-end development (server-side logic and databases).

Answer: Front-end development focuses on the visual part of a website or application that users interact with. It includes languages like HTML, CSS, and JavaScript. Back-end development, on the other hand, deals with the server-side logic and databases, using technologies like Node.js, Python, Ruby, and databases like MySQL or MongoDB.

Answer: Full-stack development refers to the development of both the front-end and back-end parts of a web application. A full-stack developer works on the client-side (HTML, CSS, JavaScript) as well as the server-side (databases, back-end programming languages) of the project.

Answer: HTML (HyperText Markup Language) is the standard language for creating webpages. It structures content on the web by using tags like <h1> for headings, <p> for paragraphs, and <a> for links. HTML provides the backbone of web pages and serves as the foundation for all web development.

Answer: CSS (Cascading Style Sheets) is used to style and layout web pages. It controls the presentation, formatting, and layout of HTML elements, such as colors, fonts, and positioning. CSS is crucial for making websites visually appealing and ensuring they are responsive across different screen sizes.

Answer: JavaScript is a programming language that enables interactive features on web pages, such as form validation, dynamic content updates, and animations. It is used alongside HTML and CSS to build responsive, dynamic websites. JavaScript runs on the browser and can also be used on the server-side with Node.js.

Answer: Responsive web design is an approach to web design that ensures web pages look and function well on a variety of devices and screen sizes. It uses flexible grids, layouts, and media queries to adapt the content and design to different resolutions, ensuring a seamless user experience across desktop, tablet, and mobile devices.

Answer: A static website consists of fixed content, usually built using HTML and CSS. It doesn't change unless manually updated. A dynamic website, on the other hand, can change content based on user interaction or real-time data from a server. Dynamic sites are often powered by server-side scripting languages like PHP, Node.js, or Python.

Answer: APIs (Application Programming Interfaces) are sets of protocols and tools that allow different software applications to communicate with each other. In web development, APIs are often used to connect the front-end of a website with back-end services or third-party services, such as databases, payment gateways, or social media platforms.
