You enter ruby code in irb. name.rb is not valid ruby code (well, it could be 
if there's an object name with a method rb, but in this case there isn't) - 
it's a file name. You could either write valid ruby code containing this 
filename (like  require "name.rb"  which would load the file and run the code 
inside it) or execute name.rb from the shell (by typing "./name.rb" or "ruby 
name.rb", not by typing in ruby code). Assuming of course that the file 
exists and contains valid ruby code.

You have not previously defined Name (at least not in the current irb 
session).
