People also ask, what is advantage of storage device?
Advantage of Storage
Storage helps in keeping a record of all the past activities and transactions. It helps in reducing the burden on the human brain in remembering things. It helps in increasing efficiency and performance.
Furthermore, what are the characteristics of optical storage? Optical storage
Data is written onto the disc by a laser and is read from the disc by another laser. The discs are cheap, but they are vulnerable to scratches. They cannot store as much data as a hard drive. A CD stores up to 800 MB , a DVD holds up to 4.7 GB and a Blu-ray holds up to 50 GB.
Similarly, it is asked, what is an advantage of optical storage over magnetic storage?
Encyclopædia Britannica, Inc. Optical storage provides greater memory capacity than magnetic storage because laser beams can be controlled and focused much more precisely than can tiny magnetic heads, thereby enabling the condensation of data into a much smaller space.
What are the advantages and disadvantages of optical disk over magnetic disks?
Optical disks are physically strong than magnetic disks and cannot be damaged easily. Magnetic disks are sensitive to be touched where as optical disks are not. Magnetic fields do not cause any effect on optical disks where as they effect the magnetic disks.
