Risk assessment is the identification of hazards that could negatively impact an organization's ability to conduct business. However, the data in RAM stays there only while the computer is running; when the computer is shut off, RAM loses its data. A hard drive is an example of non-volatile memory. Thus, volatile memory is temporary and nonvolatile memory is permanent. Volatile memory is often contrasted with non-volatile memory, which does not require power to maintain the data storage state. What is the difference between memory and storage? SRAM is commonplace in small embedded systems, which might only need tens of kilobytes or less. Most RAM (random access memory) used for primary storage in personal computers is volatile memory. Non-volatile memory (NVM) is a type of computer memory that has the capability to hold saved data even if the power is turned off. In contrast, volatile memory needs constant power in order to retain data. Data stored on a hard drive remains there regardless if the drive has power, making it the best place to store your files. Nonvolatile memory, by contrast, does not lose its contents when power is removed from the computer. It allows the user to randomly access any part of the data regardless of its position in roughly the same time. Originally it had nothing to do with volatility. All RAM except the CMOS RAM used for the BIOS is volatile. One example of nonvolatile storage devices is, ROM(Read Only Memory). RAM is considerably faster than the permanent storage devices a computer has, so it works well for its purpose. RAM is much faster to read from and write to than the other kinds of storage in a computer, such as the hard disk or removable media.
