How can we understand ruby on rails generate call in layman's term?

Disclaimer : I am a total novice to programming itself , I have done some C++ stuff only . I had an idea and wanted to code the preliminary part of the website myself. Hence , I looked around and decided to jump on to the Ruby on Rails bandwagon. But I am not quite getting the grip of the generate command and how is it being very different from scaffold. Again , please pardon me , I am starting out and thought if anyone over here can guide me to good tutorials or easy way of making it understand . Any answers, small or big are appreciated !

I am following The Intro to RoR ( Berkeley events youtube ) set but it seems outdated , so I have been trying to follow random youtube videos .

The official Rails Guides are a great place to learn all things Rails. In this case, there is a A Guide to the Rails Command Line which spells out the difference. Essentially, a Rails scaffold "is a full set of model, database migration for that model, controller to manipulate it, views to view and manipulate the data, and a test suite for each of the above." generate, on the other hand, is used to create models and controllers separately.

The obvious thing I should say here is: do both and look at the differences. If you're new and you find Rails and/or the command line daunting, play with it and figure it out. Create some new project (rails new foo) that you can throw away later. Change into the foo directory, then type rails generate scaffold Bar, take note of the files created and what's in those files, then go back to the command line and type rails destroy scaffold Post. Then do the same with rails generate controller and rails generate model. The best way to understand is by experimenting yourself.
