What is the name of the storagr device that does not allow the data on it to be erased or re written
Normally Volatile memory or storage is the real memory in the computer. It is volatile because if the power fails or is turned off the memory (RAM) is erased or reset.
It is nonvolatile, if you turn off the computer, the disc is not erased. (if you have a dvd bluray or cd and you turn off the cd, dvd, or bluray player the songs or movie on the disc is not erased). It does not use electrons to store data, it uses grooves and bumps in the disc and is read with a laser
Main memory in a computer is storage that will be erased when a computer is turned off. Backing storage is memory that will save information when the computer shuts down.
If you are talking about internal storage, the SCSI drive was the first. However, tape drives were used long before that. Many early computers didn't even have a hard drive, instead the data was simply stored in RAM, and erased after the computer was turned off.
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
Non volatile means can store data in a way that electricity flow does not matter or whether has it been plugged on or off the computer will not affect the contents or reserved data or information the device has.Examples are all secondary storage devices like (flash disks ,USB memory sticksData is stored permanentlyon the other hand VOLATILE storage like RAM temporarily store data once the computer is off all its contents/(stored data) are erased.
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
When you shut down your computer, everything in RAM is erased, but the hard disk has long-term storage for the computer.
RAM stands for Random Access Memory. It is a temporary computer storage device, i.e. all data stored in RAM will be erased after the computer is switched off. All data to be processed is first copied into RAM. For example, when you start an application it is copied into the RAM from your harddisk. Similarly, if you enter any data into the computer it is sent to the RAM.
Memory cards are flash storage, where data is stored in discrete transistor cells that can normally be erased or changed several thousand times.
In computer science ROM, stands for Read-Only Memory. A type of fixed data storage device that is manufactured with fixed contents. ROM is a non-volatile storage. It keeps its contents even when the power is switched off. It is mainly used in part as fixed storage of the lowest level bootstrap software (firmware) in a computer. Horse Isle Answer: Read Only Memory - Emma Rom stands for Read only memory. ROM has the memory the computer uses to boot up. ROM won't delete unless manually erased.
