its a hard drive
the 1 bit memory is stored in the resistor............
Yes, any data that can be stored on a hard drive can also be stored on a flash disk. A flash disk can even be configured with a boot sector and you can "boot" your computer from the flash disk.
Usually all the files are stored in the Hard Disk of your Computer.
Fragmentation. You can solve this using a disk defrag program.
Your Hard Disk is where programs and data are stored for later retrieval ( excluding virtual memory) . If a program is in execution it has to be loaded in the memory (by memory I mean the RAM), So your Java Heap has to be in the RAM and cannot reside on the Hard disk.
Some laptops provide a utility to lock a hard disk with a password. These passwords are not the same as BIOS passwords. Moving a locked hard disk to another machine will not unlock it, since the hard disk password is stored in the hard disk firmware and moves with the hard disk. Also, adding a new (unlocked) hard disk to a locked machine may cause the new hard disk to become locked. Also, note that hard disk lock passwords cannot be removed by reformatting the disk, fdisk or any other software procedure (since the disk will not allow any reads or writes to the disk, it cannot be reformatted.)You can test to determine if your hard disk is locked by attempting to access it in another laptop.
To read, there are very small electric coils that sense the magnetic polarization; these coils are mounted on arms which pivot and move across and very close to the surface of the disk. (see the image link under Sources... below) These coils read the polarization which represents the 1's and 0's of the binary information stored on the magnetic disk. The write mechanisms make use of the electricity flowing through a coil in the write head that produces a magnetic field. Electrical pulses are sent to the write head, with different patterns of positive and negative currents. The current in the coil of the write head induces a magnetic field across the gap between the head and the magnetic disk platter, which in turn magnetizes a small area on the recording medium. The Read/Write head assembly works to read and write using basically the same technology, early units used the same hardware for both, modern units can have slightly different configurations of the microscopic gaps between coils and magnets etc. for optimum performance.

Hard Disk Drive.
There are two types of Hard disk. 1:Sea gate disk 2:SATA Hard disk
1. IDE Hard Disk 2. SATA Hard Disk 3. SCSI Hard Disk 4. Ultra SCSI Hard Disk
