1. What's the difference between a cookie and a session?
Maybe cookies are more complicated. A session starts when a user logs in, and maybe you don't need a logged-in state for a cookie?

2. What's serialization and how does it come into play with cookies?
I have no idea.

3. Can a cookie be shared by more than one user? How/why?
I don't think so... a cookie is stored on a machine, isn't it? Or in the browser? Maybe if you have two people using the same machine, but it'd still be a different cookie if they had different browsers and stuff...

4. What would it mean to store a shopping cart in a cookie?

What are database tables, column, and rows? What's the purpose of each?

  Table is a collection of data organized into columns and rows.

  Rows are usually one record. Usually horizontal.
  
  Columns are usually vertical, and contain similar information about multiple records.


How's a database similar and different from a spreadsheet?

def add(*numbers)
  numbers.sum
end

def subtract(number, *more_numbers)
  more_numbers.each do |i|
    number -= i
  end
  number
end
