Risk management is the process of identifying, assessing and controlling threats to an organization's capital and earnings. Non-volatile memory also stores your computer's time and system settings even when the power is off. However, the data in RAM stays there only while the computer is running; when the computer is shut off, RAM loses its data. The most common example of volatile memory is RAM. Examples of nonvolatile memory include ROM, flash memory, and CMOS. RAM is considerably faster than the permanent storage devices a computer has, so it works well for its purpose. With the likes of external disks, you can store files on them and the files will remain stored on them even when you … A prime example of volatile memory is RAM. https://www.difference.wiki/volatile-memory-vs-non-volatile-memory SRAM is commonplace in small embedded systems, which might only need tens of kilobytes or less. This post tries to explain this statement in more details along with Java volatile examples. Example: RAM is an example of Volatile Memory. It’s much slower than main memory, but it stores more data. Unlike volatile memory, it does not require an electric charge to maintain the storage state. Volatile memory is a semiconductor technology that requires a continuous power supply to maintain stored data.
