Presentation Formats the data/syntax negotiation: agree on a common language Encryption: Scrambles the data to be unreadable File compression: data is replaced by symbols/characters
Session sets up session, maintains communication, terminates the session
Transport Segments: segments(src) and reassembles(dest) the data using sequence numbers Connection oriented(TCP): three way handshake(Syn, Syn/Ack, Ack) Connectionless(UDP): no retransmissions or ACKs, thus unreliable Reliability/error recovery Flow Control
Network Handles logical addressing(i.e. IP Addressing) Routing: best path determination
Data Link LAN 2 sublayers(ethernet) Logical Link Control: upper layer helps identify the layer 3 portal Media Access Control: provides access to the media(broadcast/contention based, token passing) Provides a physical address(Ethernet(LAN):MAC address, Frame
