Drives are storage media's
A drive is the name name for several types of storage media. There are also storage media,
which are not drives (RAM, Tape Streamers), but on these pages, we will discuss the drives.
Common to drive media is:
l A file system can be assigned to them.
l They are recognized by the operating system and they are assigned a drive letter.
During start up, drives are typically recognized by the PC system software (ROM-BIOS +
operating system). Thus, the PC knows which drives are installed. At the end of this
configuration, the appropriate drive letter is identified with each drive. If a drive is not "seen"
during start up, if will not be accessible to the operating system. However, some external drives
contain special soft-ware, allowing them to be connected during operation.
Here some examples of drives:
Storage principles
Storage: Magnetic or optic. Data on any drive are digitized. That means that they are
expressed as myriad's of 0's and 1's. However, the storage of these bits is done in any of three
principles:
Interface
Individual drives are connected to other PC components through an interface. The hard disk
interface is either IDE or SCSI, which in modern PC's is connected to the PCI bus. Certain
drives can also be connected through a parallel port or the floppy controller:
