The throughput of the telephone line is 8 kb / s, the special optical channel is 40 mb / s. How many telephone lines

The throughput of the telephone line is 8 kb / s, the special optical channel is 40 mb / s. How many telephone lines do you need to use to create a communication channel equivalent to optical bandwidth?

In order to make a correct calculation, it is necessary to use values in comparable units.

Let’s choose such Kb / s in our case.

Let us determine what speed the optical channel speed will correspond to if it is not expressed in Kb / s, when from the condition of our task we know that it is equal to 40 Mb / s:

1 MB is the same as 1024 Kb / s;

40 * 1024 = 40960.

Now let’s determine how many phone lines to use:

40960: 8 = 5120.

Answer: 5120.
