16Convert the following units. Your answer should be a whole number with no text in the answer field:
3 KiB = _____ bytes- A3072
- B3084
17How long does it take to send a 14 MiB file from Host A to Host B over a circuit-switched network, assuming:
Total link transmission rate = 64.2 Gbps.
Network is TDM, with 19 permitted users, each with an equal time slot size.
A link connection requires a setup time of 68.3 ms.
Your answer should be in miliseconds (ms) with one decimal place, and without the unit (e.g. "140.6" without the quotes)- A103.1000
- B45242
18Suppose there are 4 routers in sequence between Host A and Host B, all of which use store-and-forward routing. What is the total end-to-end delay for a packet originating from Host A with destination Host B, under the following conditions.
Each of the link transmission rates are 7.1 Mbps
The total distance from Host A to Host B along its path of transmisison is 114.9 km
The speed of propagation through the transmission medium is is 2.7 x 108 m/s
The packet size is 3 KiB
Remember that you must also uplink from Host A to the first router. Give answer in milliseconds, rounded to 1 decimal place, without units (e.g. for 0.12345 seconds you would enter "123.5" without the quotes).- A19.4
- B17.8
19Suppose there are 4 routers in sequence between Host A and Host B, all of which use store-and-forward routing. What is the total end-to-end delay for a packet originating from Host A with destination Host B, under the following conditions.
Each of the link transmission rates are 3 Mbps
The total distance from Host A to Host B along its path of transmisison is 185 km
The speed of propagation through the transmission medium is is 2.7 x 108 m/s
The packet size is 3 KiB
Remember that you must also uplink from Host A to the first router. Give answer in milliseconds, rounded to 1 decimal place, without units (e.g. for 0.12345 seconds you would enter "123.5" without the quotes).- A44.400
- B41.7
20Use the Image
- A24.66
- B24.69
21How long does it take to send a 16 MiB file from Host A to Host B over a circuit-switched network, assuming:
Total link transmission rate = 60 Gbps.
Network is FDM, with 3 permitted users, each with an equal bandwidth share.
A link connection requires a setup time of 52 ms.
Your answer should be in miliseconds (ms) with one decimal place, and without the unit (e.g. "140.6" without the quotes)- A58.700
- B58.65
22What is the total utilization of a circuit-switched network, accommodating five users with equal bandwidth share, and the following properties:
Two users each using 68% of their bandwidth share
Two users each using 41% of their bandwidth share
One user using 8% of their bandwidth share
Give answer in percent, with one decimal place (normal rounding) and no percentage sign (e.g. for 49.15% you would enter "49.2" without the quotes).- A45.20
- B45.54
23What devices reside in the network core?
- ASmart Tvs
- BDesktop
- CTablet
- DPrinter
