Remember 3.5” disks, and their capacity of 1.44 MB (two sides, HD, PC) But what did that MB stand for? How many bytes? a) 1.44 x 1000² = 1,440,000 b) 1.44 x 1024² = 1,509,949
Answer: neither. It was 1.44 x 1000 x 1024 = 1,474,560 bytes.
The standard density single sided 3.5” disk took 360 KB, back when KB usually meant 1024 bytes. This doubled to 720 KB when used double sided, and doubled again to 1440 KB when HD. And then 1440 KB was turned into 1.44 MB, thus mixing the 1000 and the 1024.
