WEB DEVELOPMENT

What is web development?

Web development is the process of building, creating, and maintaining websites. It involves multiple disciplines including graphic design, user experience design, front-end development, back-end development, and database management.

Front-end web development focuses on the visual and interactive aspects of a website. It involves using HTML, CSS, and JavaScript to create the look, feel, and behavior of a website. HTML provides the structure and content of a website, CSS is used to style the website, and JavaScript provides interactivity and dynamic behavior.

Back-end web development, on the other hand, deals with the server-side processing and data management. It involves using languages such as PHP, Python, Ruby, or Java and frameworks such as Laravel, Django, or Ruby on Rails to build the logic and functionality of a website. The back-end developer is responsible for ensuring the website is fast, secure, and can handle large amounts of traffic and data.

Web development also involves database management, where data is stored and organized for use on a website. A database management system (DBMS) such as MySQL, Oracle, or MongoDB is used to manage the data and make it accessible to the front-end of a website.

Web development is a complex and multi-disciplinary field that involves combining various skills and technologies to build functional and visually appealing websites. With the continuous evolution of technology and the increasing use of the internet, the demand for web development skills continues to grow.
