one byte = 8 bits
one kilobyte = 1024 bytes
one megabyte = 1024 kilobytes
one kilobit = 1024 bits
one megabit = 1024 kilobits

Do the math.

On nearby friendly planet Earth, 2,048,000 bits / 8 bits per byte = 256,000 bytes or 256 KB. :)

No.

Your calculations don't account for overhead.

2Mbit includes overhead bits.

256kB typically is bytes of meaningful data, which doesn't include overhead.

Overhead would include start, stop, and parity bits, error correction, etc.

So I'd say, YES.

well. that's cuz they upped the download cap to 1.7Mbps..

he didn't ask what the application was. it could be hard drive space.

Assuming he's talking about network traffic.

Not in units of speed, it coudn't be!

Besides, when hard drive space is measured, now we get into "decimal gigabytes" versus "binary gigabytes" and filesystem overhead.

And chill.... I was just pointing out something that might not have been considered. From a strictly mathematical point of view, yes the two are equal.
