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.
