Hi Guys,

I was trying to figure out what 3gb actually means. So how fast can I theoretically burn through that on a Telkom best offer 512k account?

As I (who sucks at maths) work it :

3 gigabytes =

gigabits 24
megabytes 3072
megabits 24576
kilobytes 3145728
kilobits 25165824

So I can (Theoretically) Transfer 25165824 kilobits in a month. At 512 kilobits a second this would take me 49152 seconds to accomplish. (819.2 minutes, 13.65 hours).

So if I use the Telkom ADSL to it's rated capacity, I will be capped in half a day.

So we buy half a days worth of Internet which we have to spread it out over 30 days? More than this is considered abuse? Hell, I'd rather be the seller than the buyer in this transaction.

But thats not all.

I also get 256k upstream. If that was going flat out, it would reduce the time by a third. So that reduces it to 9.14 hours. Ok, still call it half a day.

Of course these are theoretical numbers. In the real worls you probably won't be able to blow your 30 days allowance in less than a day (but only just). And these are at the rated speeds, which are very slow in comparison to, well almost everyone else.

Please feel free to point out the almost inevitable flaws in my calculations

Im no bit guru, but if you use your 512/256 adsl connectrion, to its full potential, you can chew through your 3 gig's of allocated bandwitdh in under 24 hours.
Telkom reckon though that 3 gigs is more than enough for everyone for a whole month.
Go figure
 
Hiya ,

I've got a spreadsheet where I just enter a data amount, and a speed in kbps and it returns some info...and your results match mine

3.0GB Downloads

512.0kbps line speed
57.6KB/s download speed
3456.0KB/min
3.4MB/min
207360.0KB/hr
202.5MB/hr
0.2GB/hr
4976640.0KB/day
4860.0MB/day
4.7GB/day

54613.3 - Time to download in SECONDS
910.2 - Time to download in MINUTES
15.2 - Time to download in HOURS
0.6 - Time to download in DAYS
 
Your maths is correct.

512Kbits/second = 65536 bytes per second, assuming 1024bytes = 1Kbyte.

You have 3GB, which is 3*1024 megabytes, a megabyte = 1024*1024 bytes.

So at 65536 bytes a second you 3GB will last 49152 seconds which is 13 hours 39 minutes.

Doing over 4Gig in a single day has been done before, usually by people going mad on P2P stuff.
