B、Hosts use a logical bus topology
C、Hosts must wait for an electronic signal to transfer data.
D、Hosts are directly connected to a wiring concentrator called a MSAU.
E、None of the above
答案
B
解析
Explanation:
LAN topologies define the manner in which network devices are organized. Four common LAN topologies exist: bus, ring, star, and tree. These topologies are logical architectures, but the actual devices need not be physically organized in these configurations. Logical bus and ring topologies, for example, are commonly organized physically as a star. A bus topology is a linear LAN architecture in which transmissions from network stations propagate the length of the medium and are received by all other stations. Of the three most widely used LAN implementations, Ethernet/IEEE 802.3 networks, including 100BaseT, implement a bus topology, which is illustrated in Figure 2-3.
Some networks implement a local bus topology.
