How floppy discus drives work?
A floppy track record is an obsolete storage format that was used on ad hominem computers. Each disc, typically 3.5 inches in height, held 1.44 megabytes of info.
Inside the overweight tensile case of the floppy disk is a magnetic stuff used to store entropy. It is a similar material to the arrangement material in a cassette tape recording. When inserted into a drive, the magnetic tape (which is in the shape of a circle) is spun around rapidly, much standardized a CD.
While spinning, the read/write head of the disk stops at the empty track on the disk. The computer, forrader sending any information to the disk, quickly checks for things like schema stability and whether or not the necessary space is forfeit on the disk.
The write head of the disk sends data to the disk by magnetizing certain parts of the magnetic recording tape. This suffice is similar in theory to the way the magnetic miscue on a credit card works. Once the data is on the floppy, an exact copy has been made--one is on the disk, one is on your computer. You can now take the floppy disk to any computer with a floppy drive and access your files.

How hard disk works?




A hard disk stores data in much the same way as a floppy drive, magnetic pulses atomic number 18 imprinted onto the surface of the disk by a read/write head which can to a fault then read the data back. Hard disks differ from floppies in that the data can be stored in much higher(prenominal) densities and accessed at much higher speeds by using a non-removable disk which is sealed from contaminants. Modern hard disks usually halt several disks within them (platters) and dedicated read/write heads for twain sides of each. The platters themselves are usually made of some aluminum devalue coated with a thin layer of iron oxide and are very rigid.If you want to get a full essay, line of battle it on our website: Orderessay
