Question Answer
Applicationprovides support for end users and for programs using network resources
Presentationbasic function is to convert the data intended for or received from the application layer into another format. Such conversion is necessary because of how data is formatted so that it can be transported across the network. JPEG, MP3
Session establishes, manages, and terminates connections between applications on different nodes
TransportProtocols at this layer perform functions such as segmenting data so that it can be sent over the network and then reassembling the segmented data on the receiving end. Also deals with some of the errors that can occur in a stream of data, such as dropped and duplicated packets. TCP, UDP
Networkrouting based on node addresses (IP addresses)
Data Linkresponsible for getting data to the physical layer so that it can transmit over the network. Is responsible for error detection, error correction, and hardware addressing. The term frame describes the logical grouping of data. MAC addressing, Logical Link Control (LLC)
Physicalidentifies the network’s physical characteristics, including the following specifications: Hardware, topology
