The RubyGems software allows you to easily download, install, and use ruby software packages on your system. The software package is called a “gem” and contains a package Ruby application or library.
Gems can be used to extend or modify functionality in Ruby applications. Commonly they’re used to distribute reusable functionality that is shared with other Rubyists for use in their applications and libraries. Some gems provide command line utilities to help automate tasks and speed up your work.
Platforms are based on the CPU architecture, operating system type and sometimes the operating system version. Examples include “x86-mingw32” or “java”. The platform indicates the gem only works with a ruby built for the same platform. RubyGems will automatically download the correct version for your platform. See gem help platform for full details.
Inside a gems are the following components:
Each gem follows the same standard structure of code organization:

STRUCTURE OF A GEM
Each gem has a name, version, and platform. For example, the rake gem has a 0.8.7 version (from May, 2009). Rake’s platform is ruby, which means it works on any platform Ruby runs on.Platforms are based on the CPU architecture, operating system type and sometimes the operating system version. Examples include “x86-mingw32” or “java”. The platform indicates the gem only works with a ruby built for the same platform. RubyGems will automatically download the correct version for your platform. See gem help platform for full details.
Inside a gems are the following components:
- Code (including tests and supporting utilities)
- Documentation
- gemspec
