Answer: B
NEW QUESTION # 34
How many seconds it takes for a computer to read a 10 GB file over a 2 Gbit/s link?
Answer:
Explanation:
To calculate the time it takes to transfer a 10 GB file over a 2 Gbit/s link, you first need to convert the file size and link speed to the same unit of measurement, such as bits.
1 GB = 1,000,000,000 bytes (1 Gigabyte = 10^9 bytes)
1 byte = 8 bits
10 GB = 10 * 1,000,000,000 bytes = 10 * 8 * 1,000,000,000 bits = 80,000,000,000 bits Next, divide the file size in bits by the link speed:
2 Gbit/s = 2,000,000,000 bits/s
Time (seconds) = (File size in bits) / (Link speed in bits/s) Time (seconds) = 80,000,000,000 bits /
2,000,000,000 bits/s = 40 seconds So, it would take 40 seconds for a computer to read a 10 GB file over a 2 Gbit/s link. Note that this calculation assumes ideal conditions with no network overhead, latency, or other factors affecting the transfer speed.
