A compact disk (CD) is an optical storage device.
Magnetic storage optical storage solid-state storage storage capacity
It is not an optical device. C D ROM or DVD are optical devices. Whereas a digital memory card is solid state device.
Hybrid drive
Magnetic. Opical and Solid state
Memory (RAM) usually What holds program variables during execution, but any storage medium can be used to store variables, including magnetic, optical and solid state drive.
Optical activity in a substance depends on its symmetry and chirality. Chiral molecules exhibit optical activity, where they rotate the plane of polarized light. The state of the substance, such as solid, liquid, or gas, does not significantly affect its optical activity as long as the molecular structure and chirality remain the same.
A magnet is a solid state of matter. It is typically made of materials such as iron, cobalt, or nickel that have magnetic properties.
Blu-ray is optical storage, not solid state storage.Solid state storage is electronic storage (e.g. Flash drive, SSD, DRAM, SRAM, ROM).
A magnetic drive stores data on a rotating platter using magnetism. A solid state drive is all electronic and uses neither magnetism nor moving parts.The primary advantages are that solid state drives can be faster, use less power and survive physical shocks, like dropping it on the floor, that would kill a magnetic drive.
Non-magnetic storage media include: CDs, DVDs, Laserdiscs, and Blu-Ray (optical) NAND, Flash, and SD devices (thumb drives, SD cards, and Solid State drives) RAM drives and SRAM (Static RAM) RFID and similar radio-cards (typically read-only) EEPROM and other reprogrammable data, such as Firmware (electronic) If we want to get oldschool, it can also include Punch Cards (optical)
