calculate download speed

[juanb]

Hi !

I want to download a file of 10 mb, I have an ADSL line which is 75
kilo bites per second. what is the process of calculating the time i
takes to download this file from the net ?

thanks very much

This is a very rough approximation:
Your DSL line operates at 750 kilo BITS per second.
1 BYTE = 8 BITS
Your DSL line operates at a MAXIMUM of 93 Kilo BYTES per second
Assume 12% throughput loss for overhead and error transmits
Your DSL line operates at an average of 82 Kilo Bytes per second
Under IDEAL conditions your DSL line is gonna deliver 5MB per minute

Hi,
Curious if you know what a Broadband ISP [Cable] maximum line operates at..

The typical MAXIMUM of your cable connection will be 10Mb per second. That's
ten megabits per second. Few, if any, cable companies offer this speed as
part of their normal offerings. That's cause they're saving it for later
offering at a much higher price. But basically, the current offerings from
your cable company are limited by the modem constraints of 10Mb/second.

Typical offerings from your cable company range from 256Kb to 3.0Mb per
second in a tiered pricing structure. That ranges from less than DSL speeds
to a whole helluva lot better than DSL.

My current connection, Adelphia cable, ranges between 300 KB (that's 300
KiloBytes) and 916 KB per second.

That means that under poor conditions I can download a 25 megabyte file in
slightly under a minute and a half. Under optimum conditions I can download
the same file in less than forty seconds.

Where I come from, Cable is MUCH faster than DSL.

In addition to the excelent response from CT please know that the
bandwidth on "your" cable segment is shared by all the cable modems on
that segment so the number of customers and their usage patterns can
affect your bandwidth at any given instant.
