+Please read:
+Chapter 3 Classes, Objects, and Variables
+p.86-90 Strings (Strings section in Chapter 6 Standard Types)
+
+1. What is an object? - An object is an instance of a class.  For example: “Back in Black”  could be an object of the class “albums”
+
+2. What is a variable?  A variable is a reference to an object and holds values.
+
+3. What is the difference between an object and a class?  An object is an individual instance of a class.  Objects are the data members of classes.  Objects are also referred to as class instances.
+
+4. What is a String? Strings are sequence of characters stored in a variable.  Strings can be printable characters or binary data.
+
+5. What are three messages that I can send to a string object? Hint: think methods:  split, chomp and swapcase.
+
+6. What are two ways of defining a String literal? Bonus: What is the difference between them?
+You can define them using single or double quotes.  Double quotes gives you a lot more options for using escape sequences

 1. What is the difference between a Hash and an Array?
+A hashes are more flexible as you can index them using symbols, strings and regular expressions as opposed to just integers.
+
+
 
 2. When would you use an Array over a Hash and vice versa?
+   I would use a hash if i needed to store the list using a key word or string for each variable.  An array is simpler to set up and 
+simply uses an integer as it's key value pair based on the order that the variables are in the array.  Arrays are easier to manipulate using integers.
+
+
+
+3. What is a module? Enumerable is a built in Ruby module, what is it?  A module is a collection of methods, constants and classes.  
+Ennumberable is a built in mixin which provides various capabilities of sorting data.
+
+
+
+4. Can you inherit more than one thing in Ruby? How could you get around this problem?  Ruby is a single inheritance language.  
+Mixins can be used within ruby  classes to get around this limitation.

+5. What is the difference between a Module and a Class? A module can't have instances.  A module is a chunk of reusable 
+code in it's own ruby program that i can call from another program using "requires".  Modules can contain functions and/or variables.  
+Classes are like modules with the exception that you can use them to create new instances of each other without them interfering with each other.
