A computer or laptop never has an 'A' or 'B' drive. Drives are named starting with 'C'. But why?
If you are a beginner computer user, you probably know the answer to this question. But if you are a user of the current generation, then surely the question arises in your mind that why the drive name of your computer or laptop of Windows operating system starts with 'C'?
That is, the main drive of the computer always starts with 'C' and then the other drives are sequentially 'D', 'E', 'F'. And if using USB drive on computer, then it is 'G' and 'H'. So what happened to the 'A' and 'B' drives?
Anyway, now know the answer. When computers first hit the market, they didn't have internal storage. Floppy disk drives were initially used as storage in computers. Floppy disk was initially used as 'A' drive in computers. Floppy disks came in two sizes, 5 1/4 inches and 3 1/2 inches. As a result, when both floppy disks were used in computers, they were named 'A' and 'B' drives.
Then around 1980, when the hard disk came as the internal storage of computers, it was consistently called the 'C' drive. Because computers still had 'A' and 'B' drives as external storage. A computer's operating system is usually installed on the hard disk. Gradually, over time, the use of floppy disks with very small storage capacity in computers is decreasing. And later on as the floppy disk became completely redundant, the floppy disk and the two names 'A' and 'B' departed from the computer. But since the hard disk is still intact, the main drive remains as hard disk 'C'.
However, the hard disk drive of your computer or laptop is not fixed as 'C' for life. You can change the drive name to 'A' from the computer's administrative options.
