Question 6. The Fiber Distributed Data Interface (FDDI) standard calls for nodes to be:

attached to a data bus in the form of a transmissive star coupler.

attached to a pair of fiber rings carrying signals in opposite directions.

attached to a network of star couplers that detect collisions and transmit only one signal to the next level.

attached to fibers by passive T couplers.

Question 7. The communication mode that supports two-way traffic but only one direction at a time is

simplex

duplex

multiplex

half-duplex

Question 8. The Internet Control Message Protocol (ICMP)

allows gateways to send error a control messages to other gateways or hosts

provides communication between the Internet Protocol Software on one machine and the Internet Protocol Software on another

POS terminal

data collection terminal

batch processing terminal

intelligent terminal

Question 10. What makes optical fibers immune to EMI?

They transmit signals in as light rather than electric current.

They are too small for magnetic fields to introduce current in them.

Magnetic fields cannot penetrate the glass of the fiber.

They are readily sheilded by outer conductors in cable.
