Ruby is an Object-oriented language which it very like Python language. It has a great number of libraries where you can easily extend. It is also open source so there is a lot of resources out there for it.

Rails is a Software library that extends the ruby language, Ruby is a framework for building web applications/websites it combines ruby and html, css and javascript and runs on a browser. Rails is considered Backend. It is great for for smaller projects but can also do larger projects. It uses gems for more complex libraries using Ruby Gems. (see below)

Ruby Gems a package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries (in a self-contained format called a "gem"), a tool designed to easily manage the installation of gems, and a server for distributing them.
