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.
