What is difference between memory device and storage device?

Answer 1

Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a central processing unit (CPU, a processor), implements the basic computer model used since the 1940s.

A device capable of storing data. The term usually refers to mass storage devices, such as disk and tape drives.

Answer 2

Memory (also known as "RAM", random access memory is "short term", faster access, and more pricey than storage devices. Because it costs more, it is not made to hold as much as storage. Storage devices are slower access, but cheaper and do not wipe out when they lose power. An example of a storage device is your computer's internal hard drive, or a USB thumb drive/USB stick/pen drive.

Answer 3

A storage device is used to hold data for an extended period. Hard drives, optical discs, thumb drives, and SD cards can be used in this fashion. Memory device, however, is not a term that I have often heard used. Most frequently when I have heard it, it was by someone who didn't know what to call a stick of RAM. So, presuming that you are referring to such usage of the term, I will say that RAM is the part of the computer in which data is held while in use, whether it be a school paper that the user is writing, a picture that a photographer is editing, or an answer that an Expert is transcribing to Answers.com The difference between them is that RAM is only temporary storage and must be kept energized to keep from losing what is stored. As such, if there is a power outage, what is in RAM will be lost but what is on the hard drive or other storage device will remain and be accessible once the power is restored and the computer restarted.

I hope this answers your question. If not, let me know in more detail what you are trying to ask and I will gladly assist you.
