Differentiate between volatile memory and non-volatile?

Answer 1

Non-volatile memory, nonvolatile memory, NVM or non-volatile storage, is computer memory that can retain the stored information even when not powered. Examples of non-volatile memory include read-only memory, flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy disk drives, and magnetic tape), optical disc drives, and early computer storage methods such as paper tape and punch cards.

Non-volatile memory is typically used for the task of secondary storage, or long-term persistent storage. The most widely used form of primary storage today is a volatile form of random access memory (RAM), meaning that when the computer is shut down, anything contained in RAM is lost. Unfortunately, most forms of non-volatile memory have limitations that make them unsuitable for use as primary storage. Typically, non-volatile memory either costs more or performs worse than volatile random access memory.

'''Volatile memory''', also known as '''volatile storage or primary storage device''', is [[computer memory]] that requires power to maintain the stored information, unlike [[non-volatile memory]] which does not require a maintained power supply.

Most forms of modern [[random access memory]] are volatile storage, including [[dynamic random access memory]] and [[static random access memory]]. [[Content addressable memory]] and [[dual-ported RAM]] are usually implemented using volatile storage. Early volatile storage technologies include [[delay line memory]] and [[Williams tube]].

Answer 3

If you computer has volitile memory, the RAM gets erased every time you turn off your computer. If it had non-volitile memory, it would save information in it. You can get similar effects by 'hybernating' your computer rather than shutting it down completely. It keeps about 10 watts of electricity going to the memory to save the info. Traditionally, devices such as PDA's primarily use non-volitile, while PC's use volitle. New developments in quantum spintronics may make non-volitile memory standard in home computers and laptops fairly soon.

Answer 4

Non volatile retains its information even if the power is disconnected. ..Volatile loses the stored information/settings if power is lost.

Think of it this way...if you remove the battery in your car you may lose the radio station settings and will have to reset the radio stations. That is an example of volatile memory.

Non Volatile does not require a maintained power supply.

Answer 5

Whatever information is stored in RAM (random access memory) is lost when the computer is turned off, because RAM chips need a continuous supply of electrical power to hold data or software stored in them. this kind of memory is called volatile because it is temporary in nature. By contrast another kind of memory holds data permanently, even when the power is turned off. this kind of memory is nonvolatile and is called ROM

( read-only memory).

Answer 6

Volatile memory is erased when the power flow to the memory stops. This is the sort of memory your computer uses. When the computer is shut down, the memory is deleted. RAM is the most common example for this type of memory. Nonvolatile memory is not erased when the power flow stops. Flash drives, hard drives, CDs, etc.

Answer 7

volatile means when there is a power failure,the data that you have stored in RAM is deleted if it has not been saved. whereas non-volatile means that when you have saved the data,it is permanently saved.it cannot be deleted unless you have deleted it.

Answer 8

Relating to people, a volatile memory is inconsistent, variable. Able to change without apparent motive thus making a non volatile memory stable, well ordered and consistent
