Ferrite or cobaltite crystals are within a hard disk.
It doesn't stand for anything. It's a component/s inside your Hard Disk Drive (HDD). When you save data or install programs on your computer, the information is typically written to your Hard Disk. The Hard Disk is a spindle of magnetic disks called platters. The Hard Disk is housed inside the Hard Drive, which reads and writes data to the disk.
A computer hard disk or hard drive (fixed disk) is hardware.
Its called your hard drive.
Hard Disk
The main thing that rotates inside a computer is the hard drive. The hard drive is a disk that stores all your computer's information. The information is stored magnetically, this is why a magnet can be so damaging to a computer. Also, there are fans inside a computer that help cool the components.
a hard disk is a disk inside the hard drive that stores information. A computer's hard disk, or hard drive, is not a part of or mounted on the motherboard, or any of the computer's circuit boards. The drive is installed into some part of the frame within the computer. Its location is not important, because the user does not have to physically access the drive. The hard drive does, however, have a data connection to the motherboard, over which information is transferred to and from the drive.
The computer's hard disk is hardware.
Simply connect your external hard disk to your computer. Then select the songs you want to play later, copy them and paste to your computer hard drive. And after disconnecting your external hard disk you can now play the selected songs from your computer hard drive.
The best way, I think to answer that is to define what a computer (or in this case the motherboard of the computer) needs to find or identify a hard disk. A hard disk needs a power source, a connector to attach it to the motherboard, and a controller to talk to the microprocessor of the computer. If any of these things fail the hard disk will not function and the computer will not recognize it. In general when you see the message "hard disk not found" its because the computer can't recognize the hard disk. This can be from a bad cable (that connects the hard disk to the motherboard), no power to the hard disk, or a failed controller. In my experience, its usually a bad cable but there are times when the hard disk itself will fail. Generally, hard disk cables are far more fragile than hard disks.
The OS is stored in the Hard Disk of the computer.
a hard drive is built into the computer whereas a hard disk is seperate
to make the computer function
