The children asked me why the 8 inch floppy disk has a smaller capacity than the 1 44 inch floppy di

The 8-inch floppy disk, its capacity is small, because the technology it uses is relatively backward, and the inch floppy disk has a large capacity, because his scientific and technological means are more superb, now things are getting smaller and smaller, but the capacity is getting larger and larger, you can send him the hard disk or USB disk example.

8-inch floppy disk, to 5-inch floppy disk, to inch floppy disk, to inch floppy disk, to 32M flash memory (U disk), to hundreds of U disks, until now dozens of hundreds of G U disks, technology is getting more and more advanced, so the volume is getting smaller and smaller and the capacity is getting larger and larger.

The times are developing, 8 inches out early, out late, is an upgraded product, just like now mobile phone photography is better than the previous card machine, a truth.

The first time I was invited, I was very uneasy.

I don't know if the U.S. nuclear forces use 8-inch disks, but the earliest software I've seen is the Apple II, which seems to be an 8-inch disk with a capacity of 180K. It is said that the CPU used on the American Space Shuttle is 8088, and it has been maintained until retirement. Therefore, from this point of view, it should not be said that the high-level does not pay attention to electronic informatization, but more because although the most advanced technology was used in the development at that time, due to security, compatibility and other reasons, it is really difficult to replace or the cost of replacement is too great.

After all, for this kind of thing, reliability is much more important than advancement.

Because the floppy disk in Bayan has a larger capacity than inches, it stores more things.

The child asked me why the capacity of an eight-inch floppy disk is smaller than that of an inch, and how can I play it safely? But of course, I have to tell him that if it's this hard drive, the larger the value, the smaller the storage space it will be.

I'll just tell him, anyway, he won't ask if he understands, and if he doesn't understand, he feels that he understands, that is, he just asks you a question, not necessarily to understand the question.

In a floppy disk, you need to consider not only its size, but also its thickness, which may have two or three layers.

The 8-inch manufacturing process is backward than that.

Science and technology are advancing, and what is concentrated is the essence.

Due to the development of technology, the capacity of floppy disks has increased.

I think I want this question, it's simple. It's the essence that is concentrated. Don't look at my small size, but my capacity is super large.

You said that's what you did, because of the processing problem, so at that time it could only be stored in this size, for example, now the U disk has eight G, there are 32 G.

You can him, because the density is different, the storage method is different, so this phenomenon occurs.

The child asked me why I thought that the floppy disk in inches was smaller than the old disk with a capacity of 14 inches.

Eight-inch floppy disks, five-inch and inch floppy disks, which have a smaller capacity than an inch floppy disk, are due to the low disk storage density.

We didn't learn this part, and we really don't know very well.
