Bandwidth & transfer calculations

[b4u]

Hi,

I'm trying to make some calculations of how much data is transfered to/from my computer for a period of time.

Let's imagine the following, 4 people connected to my computer, each with a maximum of 2.5Kb/s of transfer.

How much is it an entire day? I belive the calculations are as follow:

2.5Kb/s * 4 = 10Kb/s
1 day = 24 hours = 24*60 minutes = 24*60*60 seconds = 86400 seconds total
86400 seconds * 10 Kb/s = 864000 Kb = 864000/1024 Mb = 843.75 Mb

Is it correct?

Now I want to do the calculations based on another figure ... let's say I have a total of 128Kbps (kilo-bit-per-second) of total bandwidth ... how can I pick this value and check the total transfered data possible?

Is 1 Kbps = 1024 bits/sec? This scale always makes me think ...


Thanks allot for help.

You got it right. It's about 864MB for the day assuming a constant rate.

As for the second question, yes 1Kbps is 1024bits per second. The same formula would apply to this to find the maximum amount of data throughput possible.

For 128K you could theoretically transfer 11GB in one day however you have to factor in overhead of 10-20% so a figure of about 9GB is more likely.
