Ruby is a programming language that was created in 1995 by Yukihiro “Matz” Matsumoto. It is an interpreted, object-oriented language that is used to create dynamic web applications. Ruby on Rails is an open-source web application framework written in Ruby. It is designed to make the development process easier by providing a structure for all the code written in the application.
For example, if you wanted to create a web application that allowed users to log in and create their own profiles, you would need to write a lot of code in Ruby to make it happen. Ruby on Rails simplifies this process by providing a framework that already contains a lot of the code needed to create such an application. All you need to do is write the code that is specific to your application.
