bit signals - ANS-when the ping reaches the hub, it doesn't see the actual data in the message.
what does it see?
all of these choices - ANS-when a hub receives signals, what does it do? (it cleans up signals, it
strengthens the signals, it sends them out all connected ports)
all - ANS-in the simulation, what happens when Computers 2 and 4 receive the ping signal?
(send a reply, reassemble the bit signals into frames, check the destination address)
discard the frame, reassemble the bit signals into frames, send a reply, check the destination
address - ANS-what happens when computers 3 receives the ping?
computer 1, 2, 4 - ANS-once the reply reaches the hub, identify the computers that will receive it
true - ANS-the network is vulnerable to eavesdropping because a hub forwards bit signals out
all other connected ports. this means that an attacker could potentially capture and decode all
information passing through the hub
true - ANS-the primary purpose of a repeater is to extend the distance that network signals may
travel between computers on the network
true - ANS-the terms "hub" and "multiport repater" are synonymous
1) receives bit signals generated from a connected computer on one of its ports
2) cleans the signal by filtering out electrical noise
3) regenerates the signal to full strength
4) transmits the regenerated signal to all other parts - ANS-basic functions of a hub
_____ is the amount of data that can be transferred on a network during a specific interval -
ANS-network bandwidth
assume a network has 5 computers connected to a 10 mbps hub, and all 5 computers are trying
to send and receive frequently. what is the average effective bandwidth for each computer? -
ANS-2 mbps
although you can still find hubs in the workplace, they're slowly becoming obselete - ANS-true
the switch, unlike a hub, reads the data in the frame. what does the switch look for in particular?
in particular it reads the ___ and ____ of MAC addresses - ANS-source; destination
