Computers made today generally do not have any floppy drives at all. PCs traditionally had 2 floppy drives (A: and B:) but might have only one of these. The original Mac had 1 floppy drive. Early microcomputers could frequently have as many as 4 floppy drives. (I had one with this capability but I never connected more than 3 floppy drives, these were 8 inch double sided double density drives).
There are tons of kinds of drives. Floppy Disk Drives, CD-ROM drives, PATA Hard drives, zip drives, flash drives, DVD drives, SATA hard drives.... The list could go on and on and on...
Because floppy drives (like CD-ROM drives) are very inexpensive. It will cost you $10 at the high end for a brand new floppy drive, just asking a technician to look at your floppy drive could cost more than that.
External floppy drives use additional hardware to connect to a computer, whereas an internal floppy drive uses a simple cable to connect to components already integrated into most motherboards until very recently. Another factor is that external USB floppy drives are a seldom-used item, whereas an internal floppy drive could be leftover stock from when they were a common commodity in every computer.
Because floppy drives are irrelevant. A high density 3.5" floppy could hold 1.44 MB of information. That's tiny compared to the amount of data that will fit on a USB memory stick costing $1 or so.

As many as needed. In laptops/notebooks there is usually only one hard disk. In a desktop or server there could be potentially any number of disk drives. If you mean a CD/DVD drive the same applies.
Last century when desktop computers were invented they stored information on floppy disks. The last of the floppy disk to be used could take 1.44Megabyte. These days we have USB drives which will take 8Gigabyte or about 7 000 times a high density diskette
The floppy disk stores data. Before the days of large hard drives, flash disks, cds, and dvds this was the primary media for transporting data.For example if you wanted to install the old Windows 3.1x it came on a bundle of floppy disks. If you wanted to take a project from work or school back home, you used a floppy disk.
The newest commonly used storage device would be the usb flashdrives because the have more space and dont break as easily( that last part could be argued with)
Yes, an allergy could potentially cause a fever as part of an allergic reaction.
No, it cannot cause one, but it could potentially cause one to rupture if you have an existing aneurism.
