Some are, not many however.
Floppy disks are rarely used today, mainly due to the fact that they are obsolete. Flash drives, hard disk drives, and memory cards all take the role of floppy disks in a more simple fashion.
normally for backup purpouses and boot disks
Yes. Windows Vista still supports both legacy floppy controllers and modern USB floppy drives.
The A: and B: drives on a desktop computer are reserved in the BIOS for floppy disk drives. As most computers only come with one floppy disk drive only the A: drive will be visible in file explorer. If a second floppy disk drive is fitted then both A: and B: drives will be visible. Computers used to have a B: drive. It was the second floppy drive. Since people no longer copy from one floppy to another, the B: drive (and on some newer models the A: drive) has become obsolete.
Mainly lack of capacity. A floppy disk is usually 1.44 MB. Modern flash drives, hard drives, etc. are in the gigabytes and terabytes ! You can still use a floppy drive (I have a USB external floppy drive), but it will become more difficult to get new floppy disks as manufacturers abandon a rather antiquated media.
A pile of other floppy drives because they are completely redundant these days, but still have their uses from time to time, usually for boot based repairs.
There are still rear wheel drives being made.There are still rear wheel drives being made.
In Windows, Drive C: is the first hard drive.On the PC compatibles (DOS then Windows, which was a program running under DOS), drive A: was reserved for the first floppy disk drive and B: for the second floppy disk drive. Drive C: was reserved for the first hard drive.Many computers don't even have floppy drives anymore, but the first hard drive is still labeled C:
With the use of flash drives becoming standard the floppy drive is becomming obsolete just like the cassette deck or VCR. Most consumers are looking to get a good computer for a cheap price thus removing unessesary part like a floppy drive that most do no use anymore is a good way to make the computer more affordable. I believe that with Dell you can still have one added but its just not a standard feature anymore. Flash drives have many advantages over floppy drives and they continue to hold more info and become less expensive. Not to mention in a world where the internet is loaded with all types of media, a floppy disk would not hold very much as far as video or audio files.
Because they are actually floppy disks of magnetic film. They don't seem floppy when you handle them because they're housed in a rigid plastic case that lets you slide them into your computer. That is if you still have a floppy drive on your computer.
Computers have changed a LOT over time. The first computers were the size of a warehouse and to input data you had to punch holes in cards and insert them into the reader. Then the first computer for getneral public came out in the late 70's. It was completely text based, and to input or save datta you used a 5.5" floppy disk. These computers didn't have a hard drive. To use them you needed to know some programming. Now we have computers that have hard drives, use CD-ROM/DVD drives, and have an operating system.We have portable computers in the form of laptops and tablets. Even more we have phones that are minature computers themselves.
The flash drive replaced floppy disks and cd-roms as storage devices. Flash drives are still in popular usage for file storage. Some even use flash drives as back up storage for their whole computer files in the event of a crash.
