Heroes, please advise, it s still a hard disk problem!!

The hard disk is the same because the carry of the computer is calculated to the power of 2, so the calculation of the thousand digits is not 1000 but 1024, and the normal thousand digit calculation is 1000, and the 160GB marked by the manufacturer is calculated by the normal thousand digits is 160000000kb, and the minimum storage unit of the hard disk is kb, so it is counted here.

Then with the thousand-digit calculation of computer 1024, it is about a little more.

In addition, the size of the hard disk made by the general manufacturer will be a little larger than the mark, so the conclusion will be 153G.

The problem of hard disk size has been calculated from n years to thousands, but the hard disks at that time were not large, so it was not obvious.

In terms of memory, it is divided into 64 to make video memory for the integrated graphics card, generally speaking, a little will be lost when the video memory is divided, so as not to mess up the data, so the balance of 447 is still memory.

It's normal to calculate differently.

One is 1G 1024MB

The other is 1G 1000MB

It's because there are so many. LZ don't pay too much attention to it, the actual capacity is always smaller than it says. 160g and 153g are only 7g different, no need to make a fuss. And it has something to do with the file system. FAT and NTFS are a bit different.

Our conventional algorithm is 1G 1024M

However, the algorithm of the hard disk manufacturer is 1G 1000M

Do you understand?

Did you add 153g? The hard disk is less as a buffer area, or the calculation method is different, the calculation method on our general computer is 1024 for 1 trillion, 1024 trillion for 1g, but the algorithm of the hard disk may be 1g = 1000m, because the operating system identification and hardware manufacturers are different in the capacity calculation formula, so there are errors, and there is the error of the space occupied by the preset application software and the buffer swap area, etc. You look at your USB flash drive, if it's 1G, it's definitely not 1G at most more than 900 megabytes!

Your memory may be allocated to the graphics card.,I think it should be 448M.,It shouldn't be 447M.,It's reasonable to divide 64M to the graphics card!

I'm stupid to see your 160g hard drive showing 153g, and the 160g hard drive should be showing 149g.

512's memory only shows 447, I'm more stupid, 512-64=448, memory, like hard disks, has different calculation methods.

I was dizzy to see a bunch of people upstairs who didn't know how to pretend to understand, in addition to the 1st floor, the 2nd and 4th floors had to add a 1m=1000k

On the third floor, I imagined that it had something to do with the file system

On the 5th floor, which one is it that says "the hard disk is missing as a buffer area, or the calculation method is different"? Who has ever seen something with 7G cache? But the algorithm of the hard disk may be 1g = 1000m" as if you discovered this new world.

The hard disk is normal. The calculation method is not the same.

The memory is because there is still 64MB of integrated graphics card used as video memory.
