The document discusses computer networks and the OSI model. It describes the layers of the OSI model from physical to application layer and their functions. It also compares the OSI model to the TCP/IP model. The key points are: - The OSI model has 7 layers from physical layer dealing with signals to application layer dealing with network access for applications. Each layer has specific functions and examples are given. - Data moves down the layers on one side and is encapsulated into frames, packets and segments before being transmitted across networks. At the receiving side, the data is de-encapsulated as it moves up the layers. - The TCP/IP model is similar but combines some layers and focuses on internetworking
