Using the Internet - especially "surfing the Web" has become very easy. The process by which information arrives at your computer isn't magic - it's actually quite complex. In order to understand the core components of the Internet, we'll use the ISO/OSI (International Standards Organization/Open System Interconnection) 7-layer model.

The ISO/OSI model defines a networking framework for implementing protocols in seven layers. This ensures that each layer is functionally independent of the others. Control is passed from one layer to the next, starting at the top and proceeding to the bottom layer, over the channel to the other station and back up the layers. Although this information is not necessary to build a home network, it is a good idea to have a basic understanding of how your network works in order to troubleshoot future problems.

Each of the layers in the Model is associated with either hardware, software, or a combination of both. The specific details vary from one type of network to another.
