i dont know In case of magnetic storage, randomly distribuited tiny magnets present in the magnetic coating gets aligned according to the frequency and voltage levels of the information/data to be stored, thus leaving a magnetic signature of the information fed in electrical form. In case of optical storage bumps and pits are created on the medium to distinguish the variations in the signal to be stored with the help of laser beam. Depth and length of the pits corresponds to the change in information.
CD-R
A magnetic disk is a disk which stores information magnetically, and is read/written with a small magnetic head (e.g. a hard disk)An optical disk is a disk which stores information optically, usually as a series of pits and peaks, and is read/writMagnetic Storagea) Stores data in magnetic form & it doesn't use laser to read/write datab) It is affected by magnetic field.c) It has high storage capacity.d) Data accessing is high as compared to CD's and DVD's.e) Magnetic storage devices are ; Hard disk , Floppydisk, Magnetic tape etc.Optical Storagea) Stores data optically & uses laser to read/write.b) It is not affected by magnetic field.c) It has less storage than hard disk.d) Data accessing is high as compared to floppy.e) Optical storage devices are ; CD-ROM,CD-R,CD-RW, DVD etc.

there is no difference!
Some devices do not contain storage devices, or do not have enough storage space needed by a particular user. Extra storage devices such as an external hard drive can be utilized.
write detail note on secondary storage devices
THER ARE TWO TYPES OF STORAGE DEVICES: RAM(RANDOM ACCESS MEMORY DEVICE) CD WRITERAND ROM(READ ONLY MEMORY)e.g DVD ROM.Uhh no that's completely wrong there are many examples of storage devices. There is magnetic storage devices, optical storage devices, silicon storage devices, and others i cant think of.~Dawn~
No, they are permanent storage devices, only RAM is volatile storage device.
name 3 types of permanent storage devices
Explain various storage devices and their characteristics?
It's a storage that is attached internally in the device's box.
Input = Keyboard Input = scanner Output = printer Storage Devices = Hard Drive Storage Devices = Thumb Drive
