Yes both are secondary storage devices.
Primary storage devices include RAM & ROM.
Secondary storage devices include magnetic disks like hard disks and cds(optical disks)
The computer storage industry manufactures tape, magnetic, and optical storage and retrieval devices for computer systems.
CD's and DVD's are not magnetic. They are optical storage devices that are read with LASER beams.
Harddrive is magnetic. Optical storage devices examples are CDs, DVDs etc. Source: IGCSE TCI student :)
two
Neither. They are removable magnetic storage. Optical storage consist of CDs, DVDs, etc.
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.
Magnetic storage optical storage solid-state storage storage capacity
The purpose of secondary memory is storage of data that is not immediately needed for processing by the CPU. Examples of secondary devices are hard drives and optical drives.
One storage device is RAM. Also Magnetic Media, Flash Media, and Optical media. Your welcome :)
Optical storage devices are coded with areas that reflect and absorb laser light.
magnetic storage device
A cassette is a magnetic storage device. It uses magnetic tape to store audio or video recordings, allowing data to be recorded and played back using magnetic heads. Unlike optical storage devices, which use lasers to read and write data on discs, cassettes rely on magnetic fields to encode information.
