How long does it take to transfer this file from the time that you start sending the first bit of your file till the time the last bit of your file arrives at the destination. Give your answer in milli-seconds.

Firstly we need to know some data to calculate this transfer

Explanation:

1) If we want to know a transfer by bus:

We need to know file size in kilobytes, megabytes or gigabytes. Also, we need to know bus bandwidth in megabytes or gigabytes.

For example:

In this case, we use a formula:

We represent file size 1 MB = 2^20 or 1 GB = 2^30.

We represent bus bandwidth 1 MB = 10^6 or 1 GB = 10^9.

File size / bus bandwidth = 100x2^20 / 133.33x10^6 = 0.786 seconds

0.786 seconds = 786 milliseconds.

2) If we want to know a transfer via internet:

We need to know file size in kilobytes, megabytes or gigabytes. Also, we need to know internet bandwidth in kilobits or megabits.

For example:

file size / internet bandwidth = 500 megabytes / 90 megabits per seconds = 46 seconds

46 seconds = 46,000 milliseconds.
