Which factor is NOT considered in measuring network reliability?

Time it takes a link to recover from a failure

Frequency of failure

Network's robustness in a catastrophe

Network's performance speed (correct)

In a point-to-point connection, what is true about the link?

Devices must take turns using the link

The capacity of the link is reserved for transmission between two devices (correct)

It is shared among multiple devices

Multiple devices use the link simultaneously

What is the main difference between spatially and temporally shared channels in a multipoint connection?

Spatially shared channels are more secure than temporally shared channels.

Spatially shared channels have reserved capacity, while temporally shared channels are open for all devices simultaneously.

Spatially shared channels require devices to take turns, while temporally shared channels allow simultaneous use. (correct)

Spatially shared channels are dedicated links, while temporally shared channels involve sharing capacity among devices.
