Data prices go haywire

Sorry I meant 1024 megs not bytes

Too late to correct it now

hi, it's either wikipedia is wrong or you all think you know when you dont.

go to http://en.wikipedia.org/wiki/Gigabyte and see how they say :

GB has 1000 MB.

Come to think of it common logic would say:

8 bits = 1 byte
8000 bits = 1000 bytes

kilo in english (perhaps derived from Latin??) usually means 1000

Therefore 1000 bytes = 1 Kilobyte = 8000 bits
Therefore 1000 kilobytes = 1 Megabyte = 8 000 000 bits
Therefore 1000 Megabytes = 1 Gigabyte = 8 000 000 000 bits

This seems to be how wiki describes it. So who can unravel how 1 Megabyte included an extra 24 Kilobytes or 192 000 Bits?
Taking it back a step --- How did 1 Kilobyte suddenly include an extra 24 Bytes or 192 Bits??

Its the Hard Drive vs Memory thing... 1000 vs 1024 - Trying to explain it to customers is not an easy task

"2 to the 10", can't get proper formatting on here, is 1024 and computers are based on binary so that's why.

Exactly

 

[Jonny Two Shoes]

OK then if its based on Binary it still doesnt make sense.

Binary are 1's and 0's.

A 1 or a 0 is a bit.

8 bits to one byte. And so on and so forth --- Follow my calculation in my previous post.

Sorry if Im being dumb but with all this in mind where did "2 to the ten" come from??

If you have N address lines, the most memory you can address (without wasting lines) is 2 to the N. This is why memory chips, etc, generally have sizes that are powers of 2, or sums of, e.g. 2 powers of 2 (have a look at the count of system RAM bytes/kbytes given by your BIOS - it's not a nice round base-10 number).

Hard drive manufacturers probably tried to play the numbers game by using 1 GB = 1000 MB at some stage (giving inflated gigabyte specs), although I don't know if this is generally accepted.

1 kilobyte has been equal to 1024 bytes for many, many years.

 

[Jonny Two Shoes]

thanks.

So the confusion was caused by an attempt from the hard drive manufacturers to mislead the public it seems. Eish!!

Yes I have just accepted the fact that it was 1024 bytes all along until I saw this thread and suddenly started thinking about it.
