ISO/OSI Presentation Layer
manages the presentation of the data to be independent of the architecture
ISO/OSI Session Layer
Manages communication setup and termination
ISO/OSI Transport Layer
Ensures that messages reach the correct application
ISO/OSI Network Layer
Manages data addressing and delivery between networks, as well as fragmenting data for the Data Link layer. A router functions at this layer.
ISO/OSI Data Link Layer
Manages the delivery of data across the physical network. This layer provides error detection and packet framing. A bridge/switch functions at this layer. For example, delivery decisions can be based on the Ethernet address (MAC) address.
ISO/OSI Physical Layer
Describes the network hardware, including electrical signal characteristics, such as voltage and current. A repeater functions at this layer.
List the ISO/OSI Layers in the proper order.
