Question
A network link has a bandwidth of 1 Gbps (Gigabit per second). How long does it take to transfer a 1 MB (Megabyte) file over this link?Group of answer choices0.01 seconds0.1 seconds1 second10 seconds
Solution
To answer this question, we first need to understand the units of measurement.
1 Gbps (Gigabit per second) is the speed of the network link, and 1 MB (Megabyte) is the size of the file we want to transfer.
However, these units are not directly comparable because a Gigabit (Gb) is not the same as a Megabyte (MB). We need to convert them to the same unit.
1 Byte = 8 bits So, 1 Megabyte = 8 Megabits
Therefore, the file size is 8 Megabits.
Now, we can calculate the time it takes to transfer the file over the network link.
The speed of the link is 1 Gbps, which is 1000 Megabits per second.
So, the time it takes to transfer the file is:
File size (in Megabits) / Speed (in Megabits per second) = Time (in seconds)
8 Megabits / 1000 Megabits per second = 0.008 seconds
So, none of the provided answer choices are correct. The correct answer is 0.008 seconds.
