Question 9

Why was OSI developed?

Answer 9

Earlier networks could only communicate with like networks. IBM could only communicate with IBM. OSI was developed to open up that communication between manufacturers

Question 10

How do different vendor network devices allow for cross communication?

Answer 10

They use interoperable network devices and software in the form of protocols, standards so each device is compatible across the spectrum.

What does the OSI architectural model for networks describe?

Answer 11

How data and network information are communicated from an application on one computer through the network media to an application on another computer

Question 12

In the Layered approach, what is a reference model?

Answer 12

A blueprint on how communications should take place.

Question 13

In a layered approach reference model, it divides the processes required for communication into what?

Answer 13

logical groupings called Layers.

Question 14

When a communication system is designed using layers what is it referred to as?

Answer 14

Layer architecture

Question 15

What is a good metaphor for the layers in the communication system ?

Answer 15

The unique, duty specific departs of a business (service , inventory, shipping)

Question 16

What is the greatest function of OSI?
