2^20 or 10^6

At times I am confused when I see

......1Mbps speed...
.....1Mb memory....
.......1Mb packet size for transmition....
.......1Mb file size in storage....
......1Mb filesize for transmition.....


Please point out correctly where I have to use
10 power 6 and 2 power 20 .........

And rules if any for doing that...

If it is a pay review, make sure it is $2^10


I always thought that Y2K should occur in another 44 years!

In the hallway, look at the doors on the left. That's where Marketing
resides. Their 1GB = 1.000.000.000 bytes
The doors on the right is where Engineering resides . Their 1GB =
1.073.741.824 bytes.

Suffice to say that you, as a customer, want Engineering's definition.
Unfortunately, what you usually get is Marketing..

Peculiarly enough, they're right, too. Just this once...

Straight ahead are the scientists, who are rather annoyed at these
computer types having pinched their prefixes and abused them!

Actually, what you want is for both of them to use the proper
prefixes, so you know what they're saying: per the IEC, one
"engineering GB" (1073741824 bytes should properly be written 1GiB
("one gibibyte") whereas one "marketing GB" is in fact a gigabyte.

You'd get rather perplexed if someone decided that 1Kg was actually
1024 grams some of the time...
