梦老,不准嘲笑我们化学WSN。 This is a very common question, and it is due to the use of different definitions of the prefixes kilo-, mega-, and giga -. The true meanings of these are thousands, millions, and billions. However, in binary arithmetic 1000 is not an integer power, but 1024 is. Because this is close to 1000, early computer scientists started calling it a kilo also, and it continues to this day. So, we now have the two sets of definitions for these prefixes; decimal notation and binary notation. The number of bits in each is: kilo = 1000 (decimal), 1024 (binary) mega = 1000000 (decimal), 1048576 (binary) giga = 1000000000 (decimal), 1073742824 (binary) The disk manufacturer specifies the size in decimal notation, and says you have 160 (decimal) gigabytes, or 160 billion bytes. ''My Computer'' uses the binary notation and says you have 149 (binary) gigabytes, which is 149 times 1073742824, or 160 billion bytes. Both the manufacturer and ''My Computer'' are reporting the same actual size, just in two different number systems.
