Total questions: 9
Worksheet time: 5mins
What is the OSI reference model?
A cabling standard for networking
A computer architecture blueprint
A network architecture blueprint
A network device architecture blueprint
How does the OSI reference model ensure independence of layer functionality?
By encapsulating data at each layer and defining interfaces between layers
By allowing device manufacturers to implement proprietary layers
By allowing communication between computer hosts over a network
By optimising the network route between hosts
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 session layer...

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
