Detailed explanation-1: -optical storage, electronic storage medium that uses low-power laser beams to record and retrieve digital (binary) data. In optical-storage technology, a laser beam encodes digital data onto an optical, or laser, disk in the form of tiny pits arranged in a spiral track on the disk’s surface.
Detailed explanation-2: -RAM, commonly called “memory, ‘’ is considered primary storage, since it stores data that is directly accessible by the computer’s CPU.
Detailed explanation-3: -Optical disks rely on a red or blue laser to record and read data. Most of today’s optical disks are flat, circular and 12 centimeters in diameter. Data is stored on the disk in the form of microscopic data pits and lands. The pits are etched into a reflective layer of recording material.
