The OSI Layer Model<\/strong> comprises seven layers, each representing an abstract concept used in network communication. Each layer is served by the layer below it. Through traversing the OSI model, data is divided into segments, then packets, then frames, and then finally into individual bits. The data travels from the top of the model to the bottom and then back to the top at the other end of the connection.<\/p>\r\n

It is very important to be familiar with the OSI Model. Both for certifications, such as Network+<\/strong> or CCNA<\/strong> and for the real world. Network engineers will often say they see a ‘Layer 2 problem’ or an issue on the ‘Network Layer’. You will look awfully silly if you do not know what they mean when they make such references. You should know and understand the different layers and which protocols live on which layer.<\/p>\r\n

Place the seven layers of the OSI Model into their correct order by clicking on a layer’s name and then clicking on an empty box.<\/p>\r\n \r\n
