linux - Concept of Virtual Environments -

-

hope question belongs here.

as linux noob, sure question sounds confusing , heavily non-technical, please me understand this.

  • anaconda python distribution comes concept of creating environments can maintain variety of python versions , specific packages based on need. without disturbing other versions , modules!
  • rbenv same thing ruby.
  • i guess nvm nodejs.
  • in fact, simplest examples python's virtualenv , virtualenvwrapper

i need or resource read , understand how these things work exactly. learning whole concept of virtualization way?

i sure has (everything?) os, esp. linux. make these things clearer in head, best try things @ os level. there resource can find such help/tutorial/etc.?

you might find these links useful.
