Layer 1 - Physical -jay (15-04-2002 09:42):
router -> network
Physical layer defines the cable or physical medium itself, e.g., thinnet, thicknet, unshielded twisted pairs (UTP).
Layer 2 - Data Link - switches routers
Data Link layer defines the format of data on the network. A network data frame, aka packet, includes checksum, source and destination address, and data.
Layer 3 - Network
NFS uses Internetwork Protocol (IP) as its network layer interface.
Layer 4 - Transport
Transport layer subdivides user-buffer into network-buffer sized datagrams and enforces desired transmission control.
Layer 5 - Session
The session protocol defines the format of the data sent over the connections.
Layer 6 - Presentation
External Data Representation (XDR) sits at the presentation level.
Layer 7 - Application
Provides network services to the end-users. Mail, ftp, telnet, DNS, NIS, NFS are examples of network applications.
