The Deep Web

The internet has changed the way information is handled and it might be scary to find out how much information is really out there about you. I was surprised for sure.
First let clear up what exactly the deep web is. For this discussion we will classify it as data that is publicly availiable but that is not necesarily indexed by google or yahoo or other search engines for one reason or another.
One reason it might not be publicly availiable is because you might have to use input on some websites to come up with data. Google or other bots are not very good at that.
For instance:
if you go to this website and input your name, this is input that google could not just automate.

Internet Net-Work Model

In this article, I will discus the 5 layers of the Internet Network Model and what they do.  This model is not the same as the OSI model from which you are probably familiar, but it has many similarities.

  1. Physical layer – This is the lowest layer. It mainly is related to transmitting data bits over the actual physical line of wire or other medium.
  2. Data Link Layer – This layer is concerned with creating and understanding those messages and data bits that are transmitted over the wire.
  3. Network Layer – This is the layer that specifies the routes or paths along which a message should travel.
  4. Transport Layer – This is the layer that keeps up the logical connection legitimate for the duration of the request.
  5. Application Layer – This is the layer at which most people see and affiliate with the most. This includes the applications on the computer most people use to carry out their internet requests.
