3. Hubs offer the ability to segment network traffic, limiting traffic to those networks where it belongs.
_________________________
ANS: F, Bridges
PTS: 1 REF: 163
4. A(n) broadcast flood is the saturation of network bandwidth by excessive transmissions from devices
attached to the network, which can result in a virtual standstill of traffic.

7. A channel bank is a large-scale multiplexer that aggregates telecommunications channels in a
centralized location such as a POP. _________________________
ANS: T PTS: 1 REF: 182
8. A(n) USB is a standard for connecting all kinds of peripherals, such as printers, modems, and tape
drives, and in many cases is replacing the use of traditional parallel and serial ports.
