Why doesn't the computer have a and B disks?

What is the computer A and B disks?

Speaking of why the computer does not have a and B disk, it will be involved in the beginning of the development of computer, the computer has just developed, or a no hard disk era, in that era we store data through a A, B floppy disk storage, and this a disk and the floppy disk storage space is very small, A disk storage size is 1.44MB, the shape size is 3.5 inch floppy disk, mainly in order to store operating system files. The storage size of the B-disk is 360K. The shape size is 5.2 inch floppy disk, is used to store the general file, basically is the random preservation several documents to be full.

With the gradual development of the computer, and then the hard disk C.D.E disk, these hard disk hundreds of MB hard disk capacity has been far more than 1.44MB of a and 360K B-disk. Later, more storage devices, such as a USB flash drive, a variety of hard disk drive letter. These mobile hard drives, SD cards, with the development of technology, storage devices are easy to use and the capacity is getting bigger. For the floppy disk, a disk, there is no need to exist, can be said to be replaced can also be said to be eliminated.

Second, a disk is the oldest disk, although it is a floppy disk, then why the computer has not been found?

Because it is a floppy disk, a, b two drive letter is the system assigned to the floppy drive, storage space is very small, the speed of data transmission is very slow, and from the start of the C drive is the storage of the hard disk back and forth, and your computer if you do not have the floppy drive installed, in My computer is no A, a, Because now the computer does not need a mandatory installation floppy disk, if you installed the floppy drive will appear a floppy disk drive a disk, no words will not show.

For the contact with the computer later, we have been unable to find a disk and B disk traces, has no one to care about whether the two of the disk still exists. Maybe you can only find them at the Junkyard and the museum! Maybe the C and D drives will be eliminated and forgotten by others in the future, so who can expect the future?

A and B disks in the computer are floppy drives that were traditionally left behind. A netizen said is a disk into my document, B disk became a network neighborhood, do not know how you look, we can also understand it.
