So, you want to learn about Computers, Networks and the Internet? Feeling a little overwhelmed by how complicated they are?
All of these technologies are built out of small pieces. That is, each piece was developed all by itself, and the pieces where then put together to make the more complicated systems. To make learning about computers and especially networking or the Internet a little easier, you can start with the OSI Model. If you understand the concepts that go into the OSI Model, you can use the OSI Model as a framework for helping you understand how the pieces that go into networking fit together and how they rely on each other to create the web surfing experience.
