Question 1. 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 2. Which of the following device is used to connect two systems, especially if the systems use different protocols?

Hub

Bridge

GateWay

Question 3. Which of the following refers to the terms "residual error rate"?

the number of bit errors per twenty four hours of continuous operation on an asynchronous line

the probability that one or more errors will be detected when an error detection mechanism is used

signal to noise ratio divided by the ratio of energy per bit to noise per hertz

Question 4. Which of the following technique is used for fragment?

a technique used in best-effort delivery systems to avoid endlessly looping packets

a technique used by protocols in which a lower level protocol accepts a message from a higher level protocol and places it in the data portion of the low level frame

one of the pieces that results when an IP gateway divides an IP datagram into smaller pieces for transmission across a network that cannot handle the original datagram size
