What is meant here?

In the "Head First Rails" book, it mentions the following:

If the matching route contains symbols, then the Routing system will create "matching parameters" in the request parameters table params[. .. ].....

I want to ask about matching parameters. Does that mean that if we have the following symbols:

:id :controller :action

So, does "create "matching parameters" in the request parameters table params[. .. ]" mean the following:

params[:id, :controller, :action]

And, one final thing. What is the "Routing system"? Is it routes.rb?

Thanks.

I think params[...] should NOT be written as I wrote it in my question like this: params[:id, :controller, :action]?

It should be written as follows instead?

params[:id] params[:controller] params[:action]

?

Or, both are the same?

It's a bit more than that - routes.rb is the means by which you configure the routing system, which could be broadly described as the part of rails that dispatches incoming requests to individual controller actions.
