Web development is the practice of building and maintaining websites. It involves a range of activities, including web design, front-end development, and back-end development.

Back-end development, also known as server-side development, involves building and maintaining the systems that power the front end of a website or web application. This includes working with server-side languages, such as PHP or Ruby, and databases, such as MySQL or MongoDB.
Overall, web development is a broad field that involves a range of activities related to building and maintaining websites and web applications. It is an important part of the online world, as it allows businesses and organizations to have a presence on the web and reach a global audience.
