Will the data stored in RAM be lost after a power outage?

The data stored in ram will be completely lost after a power outage. Random access memory (RAM) can both store information into and read out information from designated units; any information stored in RAM will be lost after a power outage, so RAM is a volatile memory.

The data stored in RAM will be completely lost after a power outage.

The computer's memory is divided into: internal memory and external memory. Internal memory is an integral part of the computer host, and it directly exchanges information with the CPU. The internal memory is composed of two parts: read-only memory and random access memory. The characteristics of read-only memory (ROM): the stored information can only be read out, not written, and the information will not be lost even if the power is turned off. The characteristic of random access memory (RAM) is that the accessed information can be read or written, and all information is lost after a power outage.

Random Access Memory (English: Random Access Memory, abbreviation: RAM), also called main memory, is an internal memory that directly exchanges data with the CPU. It can be read and written at any time (except when refreshing), is very fast, and is often used as a temporary data storage medium for the operating system or other running programs. When RAM is working, information can be written (stored) or read (retrieved) from any specified address at any time.

The biggest difference between RAM and ROM is the volatility of data, that is, the stored data will be lost once the power is turned off. RAM is used in computers and digital systems to temporarily store programs, data, and intermediate results.
