solid,magnetic and optical memory
what is solid memory?
An all-electronic storage device that is an alternative to a hard disk. Employed in myriad products, including mobile devices, iPods, cameras, laptops and desktop computers,solid state drives are faster than hard disks because there is zero latency
what is magnetic memory?
magnetic storage. A system of storing information through the alignment of small grains in a magnetic material. Once the grains have been aligned by an external magnetic field, the information remains stored for long periods of time.
Magnetism: Data Storage
what is optical memory?
A computer memory that uses optical techniques which generally involve an addressable laser beam, a storage medium which responds to the beam for writing and sometimes for erasing, and a detector which reacts to the altered character of the medium when it uses the beam to read out stored data.
