WEB DEVELOPMENT

             Web development is the process of designing, building, and maintaining websites and web applications that are accessible through the internet. It involves creating everything from simple informational websites to complex applications such as online shopping platforms, social media sites, and banking systems.

         *Types of Web Development: 
                      1. Front-end Development ,
                            Focuses on the user interface and user experience.
                            Uses technologies such as HTML, CSS, and JavaScript.
                            Ensures websites are visually appealing, responsive, and interactive.
                     2. Back-end Development ,
                            Handles the server, database, and application logic.
                            Uses programming languages such as Python, Java, PHP, Node.js, and C#.
                            Processes user requests, stores data, and manages website functionality.
                    3. Full-stack Development ,
                             Combines both front-end and back-end development.
                             Full-stack developers can build complete web applications from the user interface to the server and database.

              *The main elements of Web development:
                   -  Front-end (client side): Everything users see and interact with — layouts, colors, buttons, forms, and animations. Common technologies:                                 HTML, CSS, JavaScript.
                  -  Back-end (server side): The logic that runs on a server — handling users, databases, payments, authentication, and APIs. Common                                                technologies: Node.js, Python, PHP, Java, Ruby
.                - Database: Stores and retrieves data such as user accounts, products, orders, and posts. Examples: MySQL, PostgreSQL, MongoDB.
