Networking ISO 7 layer model
- Application - e.g. NFS, NIS
- Presentation - e.g. XDR, structures the data
- Session - e.g. RPC, executes procedure calls remotely
Presentation and Session together control the creation and lifetime of connections
and data format
- Transport - e.g. TCP, UDP, ensures data is suitable size for network and
provides transmission control. TCP monitors transmission and lost packets are resent.
UDP doesn't monitor and it is up to the receiving app to request the resending of lost
packets
- Network - e.g. IP, responsible for getting packets from A to B
- Datalink - how data is put into chunks
- Physical - gets packets to or from network
Datalink and Physical together define the network interface, e.g. ethernet
