What type of storage stores data that Cannot be erased?
CD-ROM, DVD-ROM, and BD-ROM refer to read-only optical storage disks. The data written on them is permanent and cannot be removed or overwritten. This is why they can’t be used as a personal storage. Instead, they are typically used for software installation programs.
Can ROM data be erased?
Erasable programmable read-only memory (EPROM) can be erased by exposure to strong ultraviolet light (typically for 10 minutes or longer), then rewritten with a process that again needs higher than usual voltage applied.
What is used to store data that Cannot be changed?
ROM is memory that cannot be changed by a program or user. ROM retains its memory even after the computer is turned off. For example, ROM stores the instructions for the computer to start up when it is turned on again.
Which devices does not permanently store data?
In comparison to permanent storage, non-permanent storage, also called volatile memory, is a storage device whose data is lost when its power source is disconnected. Examples of non-permanent storage include CPU cache and RAM.
What are the non-volatile storage device?
Hard disks are nonvolatile storage devices that are used to store and retrieve data quickly. Nonvolatile storage is physical media that retains data without electrical power. This means that no data is lost when the computer is powered off, making hard disks suitable for permanent storage of information.
Which is the non-volatile storage?
Examples of non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.
