Beginner RoR student with a question regarding “rails server” and WEBrick [ in reference to railstutorial.org]

Hello everyone!
I am a brand new to rails and I have been working through the tutorial found at railstutorial.org. I have gotten caught up on step 1.2.5 where we run our first rails server on a local host.
I have updated my gemfile to the specifications which are specified in step 1.2.4, and ran bundle update & bundle install. Everything on that end appears to be correct...
Now when I run 'rails server', much more appears in my command prompt than is listed on the tutorial.

Tutorial shows this when 'rails server' is executed:
$ rails server

=> Booting WEBrick

=> Rails application starting on http://0.0.0.0:3000

=> Call with -d to detach

=> Ctrl-C to shutdown server

When I run 'rails server', I get this:
C:\Sites\rails_projects\first_app>rails server

=> Booting WEBrick

=> Rails 4.0.5 application starting in development on http://0.0.0.0:3000

=> Run `rails server -h` for more startup options

=> Ctrl-C to shutdown server

Exiting
