The OSI presentation layer...

• Segments and delivers data, correcting transmission errors

• Opens and maintains comm's channels, authenticating data comm's.

• Converts data, encrypts data, and translates data

• Manages the user interface and processes data before handing it off to the user

The OSI application layer...

• Segments and delivers data, correcting transmission errors

• Opens and maintains comm's channels, authenticating data comm's.

• Converts data, encrypts data, and translates data

• Manages the user interface and processes data before handing it off to the user

The OSI network layer...

• Segments and delivers data, correcting transmission errors.

• Manages electrical, optical, and radio transmission of data bits

• Routes data frames locally and manages local physical addressing

• Routes data packets between networks and manages global logical addressing

The OSI transport layer...

• Segments and delivers data, correcting transmission errors

• Opens and maintains comm's channels, authenticating data comm's.

• Converts data, encrypts data, and translates data

• Manages the user interface and processes data before handing it off to the user
