OSI Model

OSI Model
OSI Model was born 1970
It means to help vender (hardware company) create interoperable network devices and software in the form
of protocol so that different vender network could work with each other
There are 7 Layer of ISO Model

Application
Presentation
Session
Transport
Network
Data Link
Physical

Application Layer
 Provides a user interface.
Ex File, Message, Data encrypt, Data Compress
Presentation Layer
 Present data
 Handle processing such as encryption
Session Layer
 Keep different applications’ data
Transport Layer
 Provides reliable or unreliable delivery
 Perform error correction
Network Layer
 Provides logical addressing, which routes used for best path determine
Ex Router
Data Link
 Combine packet into bytes and bytes into frame
 Provide access to media using MAC
Physical
 Moves bits between devices
Ex Wire Speed, Pin out and Cable
