Cybercriminals Focusing on Mobile Platforms

If I were to tell you four years ago that cybercriminals were going to focus on mobile phones instead of computers would you believe me?

The OSI Layer

It is the foundation that makes understanding networks possible the wonderful OSI layer. While studying for the CCENT exam I had a basic understanding of the OSI Model but when reviewing the material I found myself saying over and over, "Oh ya I remember that"! meaning I totally forgot about a certain protocol or how and what services where in each layer. So I wrote down the basics on the  ITS forum and decided why not post it here as well.
