Take a look at the section: The Basic Types.

2 - What is the use of “puts” in Ruby and what is diffrence between
“puts” and “print” ?

As Josh says it’s easy to try and see:

puts “a”
puts “b”
print “a”
print “b”

Or also, you can read the explanation here:

puts: http://ruby-doc.org/core/classes/IO.html#M002252
print: http://ruby-doc.org/core/classes/Kernel.html#M005952

There for a RUBY literal String is as follows:

“this is a string, literally”
