Magnetic storage:Yes magnetic tapes are permanent storage and are the best permanent storage. These are very slower storage but are very cheap storage then RAM or other kind of memory.
What is mindless behavior real. Number
No, they are permanent storage devices, only RAM is volatile storage device.
There are three types of internal storage devices mainly optical, semi conductor and magnetic storage. Compact disk is an example of magnetic storage whereas silicon chip is an example of a semi conductor storage device.
A hard drive comes with the Computer. A hard drive is considered permanent as opposed to magnetic tape. The data in tape can be accessed only serially whereas randomly in hard drive.
Magnetic storage optical storage solid-state storage storage capacity
For both the magnetic and electric (static) fields, energy is considered to be stored in the field.
the magnetic storage devices, use magnetic property of the materials to save data in bits.
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.
Most importantly to us, the earth has a permanent magnetic field.
Yes; if the storage is on magnetic media then that can be altered by magnetic and electric fields.
