  • B. FALSE

  • Correct Answer
  • FALSE 

    Explanation

    "CD-ROM is a semiconductor memory" is a FALSE statement.


     


    Compact Disc-Read-Only Memory, a type of optical disk capable of storing large amounts of data -- up to 1GB, although the most common size is 650MB (megabytes). A single CD-ROM has the storage capacity of 700 floppy disks, enough memory to store about 300,000 textpages.


     


    Semiconductor memory is a type of semiconductor device tasked with storing data. There are two electronic data storage mediums that we can utilize, magnetic or optical.


     


    Magnetic storage:


    * Stores data in magnetic form.


    * Affected by magnetic fields.


    * Has high storage capacity.


    * Doesn't use a laser to read/write data.


    * Magnetic storage devices are; Hard disk , Floppy disk, Magnetic tape etc.


     


    Optical storage:


    * Stores data optically, uses laser to read/write.


    * Not affected by magnetic fields.


    * Has less storage than a hard disk.


    * Data accessing is high, compared to a floppy disc.


    * Optical storage devices are; CD-ROM,CD-R, CD-RW, DVD etc.


     


    There is also volatile memory. This is memory that loses its data once power is cut off, while non-volatile memory retains data even without power.
