under contsruction

PRIMARY STORAGE	FUNCTION
RAM	o RAM is volatile, which means the program and data will be lost when the computer is turned off. o Data from RAM can be read or retrieved and written or stored during processing
ROM	o ROM is non-volatile which means is holds the programs and data event when computer is turned off. o data from ROM can just be read only.

Secondary storage is an alternative storage.

It is very useful to store programs and data for future use

TYPE	DESCRIPTION	EXAMPLE
Magnetic Medium	Magnetic Medium is a non-volatile storage medium. It can be any type of storage medium that utilizes magnetic patterns to represent information. The devices use disks that are coated with magnetically sensitive material.	Magnetic disk: floppy disk, hard disk, magnetic tape; video cassette, audio storage reel-to-reel tape
Optical Medium	Optical Medium is a non-volatile storage media that holds content in digital form that are written and read by a laser. These media include various types of CDs and DVDs.	CD, CD-ROM, and DVD CD-R: CD-RW, DVD-RW, and DVD-RAM
Flash Memory	Flash Memory is a solid-state, non-volatile, rewritable memory that functions like RAM and a hard disk drive combined. Flash memory store bits of electronic data in memory cells just like DRAM (Dynamic RAM), but it also works like a hard disk drive that when the power is turned off, the data remains in the memory.	Memory card, Flash drive
