It has 7 levels, each level has its own operational functionality. All operations performed on the network work on any of these layers. Before going into further details, consider the diagram below, which represents the 7 levels along with the description of the task they actually perform. All readers are advised to learn the names of layers along with their function in detail as it is important from interview point of view. All operations performed by network components or any type of operation that includes network protocols work on any of these layers. For example, let's consider a File Transfer Protocol (FTP) based network application, which will operate on the first layer of the OSI.
