The document discusses front-end and back-end web development. It defines front-end development as focusing on how the website looks to users, involving HTML, CSS, and JavaScript. Back-end development focuses on how the website works behind the scenes, using languages like Ruby, PHP, C++, and Java to handle business logic and data. The development process can separate these responsibilities, with front-end developers focusing on content, structure, and design, while back-end developers focus on functionality.
