Both bus and tree topologies are characterized by the use of multipoint (1).For the bus, all stations attach, through appropriate hardware (2) known as a tap, directly to a linear transmission medium, or bus. Full-duplex operation between the station and the tap allows data to be transmitted onto the bus and received from the(3). A transmission from any station propagates the length of the medium in both directions and can be received by all other (4). At each end of the bus is a (5) , which absorbs any signal, removing it from the bus. 空白（1）处应选择（）

第9题：
Which two statements describe the operation of the CSMA/CD access method, which is in use on the Ezonexam network? (Choose two)
A. After a collision, the station that detected the collision has first priority to resend the lost data.
B. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
C. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
D. The use of hubs to enlarge the size of collision domains is one way to improve the operation of the CSMA/CD access method.
E. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
F. After a collision, all stations involved run an identical backoff algorithm and then synchronize with each other prior to transmitting data.
