Answer

When two computers are assigned the same IP address, it creates an IP conflict on the network. This can lead to instability and disruption in communications, as data packets may be sent to the wrong device, resulting in data loss. For proper network functionality, each device must have a unique IP address to ensure data is routed to the correct recipient.

Step 2

Identify the network topology that requires a server.

Answer

To find the number of bytes transmitted in 10 seconds, we can use the expression:

extTotalBytes=extDataRate(Gbps)imesextTime(seconds)imesextConversionFactor ext{Total Bytes} = ext{Data Rate (Gbps)} imes ext{Time (seconds)} imes ext{Conversion Factor}

For this case, the expression would be:

ext{Total Bytes} = 3 ext{ Gbps} imes 10 ext{ seconds} imes 10^9 ext{ bits/Gb} imes rac{1 ext{ byte}}{8 ext{ bits}}
