Explain Cdrom Access Is Random Or Semi Random Or Sequential?

Answer»

CDROM access is sequential.
Magnetic sequential access MEMORY is typically used for secondary storage in general-purpose COMPUTERS due to their higher density at lower cost compared to RAM, as well as resistance to wear and non-volatility. Examples of SAM devices still in use include hard DISKS, CD-ROMs and magnetic tapes. HISTORICALLY, drum memory has also been used.
