What are the three storage technoclogies?
Magnetic
Hard Drive
Cache
Solid State
RAM
ROM
Optical
Registers
A magnetic hard disk stores data using magnetism on the platter, which spins and an actautor moves the drive head to the correct track with the data on it.
North and South magnetuic fields on the platter are able to store the data in binary.
Label the magnetic storage process device:
A laser beam burns a pit onto the surface of the disk, and if a pit is present this can represent binary, as 1, and if it's not present it could be a 0.
Label the optical disk storage process:
Solid State storage is the faste of the three types of storage. It is used in more expensive hard disk drives, USB and memory cards.
Information can be accessed fast as the SS doesnt need to wait for a disk to move to access it.
Solid State storage devices hold data using electronic manual automatic( electronic, manual, automatic ) switches. Switch open broken produce( open, broken, produce ) = 1, and switch closed = 0. This technology is called 'Flash Secondary Independant Switch( Flash, Secondary, Independant, Switch ) Memory'.
