The OSI model is a logical model not a physical one
OSI Model made up of 7 layers
7.|Application Layer|
6.|Presentation Layer|
5.|Session Layer|
4.|Transport Layer|
3.|Network Layer|
2.|Data Link Layer|
1.|Physical layer|
Application Layer – Provides user interface
Presentation Layer – Presents data handles processing such as encryption
Session Layer – Keeps data separate
Transport Layer – Provides reliable or unreliable delivery
Network Layer – Provides logical address which routers use for path determination
Data Link Layer – Provides access to media using MAC address
Physical Layer – Moves bits between devices
