When speaking of speed I use 1Kbps=1000 bps. But when I speak of ram,
storage then 1Kb = 1024bits. The problem is I don't know why !?!?

Willem,
In networking (and computing at large I think) 1Kbps is 1000bps, not
2^10 (1024) bps as it really should be. This also goes for 1000Kbps being
1Mbps, and 1000Mbps being 1Gbps, etc. This is also true for storage if I
remember correctly, and 1Gb of storage is 1 billion bits, not 2^30 bits.
It's probably just a marketing thing, or if there is some real reason I'm
sure Howard knows ;)
HTH,
