that's true! ...and NON-volative, by contrast, does lose its contest when the power is removed from the computer.
yes, and nonvolatile does not
RAM, or random access memory.
Assuming you mean 'volatile' - RAM is volatile... When you turn the power off - RAM loses its contents. Non-volatile RAM is able to retain its contents even when the machine is turned off.
No, cache memory is a volatile type of memory, meaning the data stored in cache memory is lost when the power is turned off. Non-volatile memory, on the other hand, retains data even when the power is turned off.
Registers are considered volatile memory because they store data temporarily and lose their contents when the power is turned off or the system is reset. They are used by the CPU for quick access to data and instructions during processing. In contrast, non-volatile memory retains data even when not powered, such as hard drives or flash storage.
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.
Volatile is RAM and non-volatile is like a hard drive. More specifically, "Volatile" storage will erase its contents when power is removed, while "Non-volatile" storage will have permanently stored the data (until specifically told to erase it), even after power is removed.
DRAM is volatile.
RAM Memory is "Random Access Memory", meaning that any word of memory can be accessed randomly, in any order; that is, without starting at the beginning and reading the memory like a tape. RAM memory is usually volatile, meaning that its contents are lost when the power is turned off.
Main computer memory is called volatile memory. It holds data only as long as it is provided power. When you turn off the computer, you remove power from the memory chips and they loose the ability to hold data. If you want to keep your information, ensure you save it to the computer hard drive before you switch off the computer.
The primary difference if the permanence of the data held in the memory. When talking about volatile and nonvolatile memory in the context of computers, we're usually referring to RAM(volatile) and the hard drive(nonvolatile). Volatile means that the memory must be receiving power in order to hold its contents. RAM must be fed power or the data on the RAM will be lost. A hard drive is nonvolatile, meaning it does not need power to keep data stored on it. This is why you install programs and photos etc to the hard drive. If you put them on RAM, it would disappear every time you turned off the PC!
Storage can be both volatile and non-volatile. Volatile storage, like RAM, loses its contents when the power is turned off, while non-volatile storage, such as hard drives and SSDs, retains data even without power. Therefore, whether data is lost depends on the type of storage being used.
