1.physical layer
2.dataq link
3.network
4.transport
session

application

There are 7 OSI layer:
*physical layer
*data link
*network
*tranport
*session
*presention
*application

There are 7 layers in OSI, the short cut for this "APSTNDP"

- Application Layer
- Presentation Layer
- Session Layer
- Transport Layer
- Network Layer
- Data Link Layer
- Physical Layer

There are seven layers in OSI,they r,
                    1)Physical layer
                    2)Datalink layer
                    3)Network layer
                    4)Transport layer
                    5)Session layer
                    6)Presentataion layer
                    7)Application layer

there are seven layers

1. application layer
2. presentations layer
3. session layer
4. transport layer
5. network layer
6. data link layer
7. physical layer

There are 7 layers in the osi model;
-Application layer 
-presentation layer
-session layer
-transport layer
-network layer
-data link layer
-physical layer

NB:Always the physical layer is considered the first layer.
