Ruby is a general purpose programming language created by Yukihiro Matsumoto, while Rails is a web application framework built with Ruby and created by David Heinemeier Hansson. Rails uses the model-view-controller (MVC) architectural pattern, with the routing looking up the controller for a request, the controller processing the request and loading data from models, and the view handling presentation. Rails provides tools for common tasks in web development like routing, views, controllers, and connecting to databases.
