What type of storage device uses spinning disks to store data?
What is a hard disk drive (HDD)?
What type of optical media is commonly used to store music or videos?
What is a CD or DVD?
What is the main advantage of solid-state drives (SSDs) over hard disk drives (HDDs)?
What is faster read/write speeds and no moving parts?
What type of storage allows data to be accessed remotely over the internet from any device?
What is cloud storage?
Which type of storage device uses electrical circuits to store data but has no moving parts?
What is a solid-state drive (SSD)?
What is the main material used in magnetic media for storing data?
What is iron oxide or cobalt alloy?
What is the technology used by optical discs to read and write data?
What is laser technology?
Why are solid-state drives (SSDs) less prone to physical damage compared to hard disk drives (HDDs)?
What is because SSDs have no moving parts, while HDDs rely on mechanical components?
What is the primary advantage of cloud storage over physical storage devices?
What is the ability to access data from anywhere with an internet connection.
Why are DVDs considered sequential access rather than random access devices when watching a movie?
What is because data is read in a set order to play video properly?
How is data read or written in a hard disk drive (HDD)?
How does the read/write head move over the spinning disk to magnetize or detect data?
What is the difference between a CD-R and a CD-RW?
What is that a CD-R is write-once, while a CD-RW is rewritable?
What type of memory is used in SSDs to store data?
What is NAND flash memory?
What technology allows for the storage of data across multiple locations or servers for redundancy in cloud storage?
What is data replication or mirroring?
In terms of speed and durability, what is one disadvantage of using magnetic tapes for backups?
What is slow data access time and risk of wear over time?
What is the primary difference between a hard disk drive (HDD) and a floppy disk?
What is the size and data storage capacity, with HDDs offering significantly more storage space and speed?
How is data organized on a Blu-ray disc compared to a DVD?
What is that Blu-ray uses a shorter wavelength laser, allowing for more data to be packed into smaller spaces, resulting in higher storage capacity?
What is the term used for the limited number of write cycles that can be performed on an SSD?
What is wear leveling?
Which futuristic storage technology involves using DNA molecules to store data?
What is DNA data storage?
n terms of speed and durability, what is one disadvantage of using magnetic tapes for backups?
What is slow data access time and risk of wear over time?
Why is data stored on magnetic media susceptible to being corrupted by magnets or external interference?
What is because magnetic fields can alter the alignment of the particles on the storage medium, causing data corruption?
What is a significant drawback of optical media when compared to magnetic storage or solid-state storage?
What is the slower read/write speeds and lower capacity?
How does the endurance of an SSD compare to the longevity of a hard disk drive in terms of data write cycles?
hat is that while HDDs may last longer in terms of write cycles, SSDs have a higher risk of failure after many write operations due to the limited number of program/erase cycles in NAND flash memory?
What is one of the main challenges of implementing quantum storage as the future of data storage?
What is the difficulty in maintaining quantum coherence and stabilizing quantum states over long periods?
What storage device is commonly used in CCTV systems and requires large capacity with frequent rewriting?
What is a hard disk drive (HDD)?
