Drives and operating system

Drives and operating system
The drive must be assigned a drive letter. That is a task for the operating system, which must be able to recognize the CD-ROM
drive. That is usually no problem in Windows 95. However, the alphabet can be quite messy, if there are many different drives
attached. Each drive must have its own letter. They are assigned on a first come first-serve-basis.
The CD-ROM drive usually gets the first vacant letter after other existing drives, typically D, E, or F. But the letter can be changed.
Once the CD-ROM spins and the operating system (DOS or Windows) has "found" the CD-ROM drive, data can be read for
processing. Now the CD-ROM works like any other drives. Only, it is Read Only Memory!
