Computer Science 2.1.1
  1. The Nature and Need for Abstraction
    1. Abstraction is essentially filtering out and ignoring characteristics we don't need to concentrate on those we do.
      1. Abstraction allows us to create a general idea of what a problem is and how to solve it.
        1. If we do not abstract, then we may end up with the wrong solution to a problem.
        2. The Difference between Abstraction and Reality
          1. Abstraction differs from reality as it removes all unnecessary details in order to focus on the general idea.
          2. Abstraction in Programming Languages
            1. Generation 1 - Machine Code - Hard to read and easy to make mistakes.

                1. Generation 2 - Mnemonic Codes - Fairly difficult at first but you can kind of see what it is doing.
