What content will be lost after shutting down?

After the computer is powered off or shut down, the data in the random access memory will be lost.

Random access memory (random access memory , RAM), also known as "random access memory", is an internal memory that directly exchanges data with the CPU, also called main memory (memory). It can be read and written at any time, is very fast, and is often used as a temporary data storage medium for the operating system or other running programs.

The contents of the storage unit can be taken out or stored at will as needed, and the access speed has nothing to do with the location of the storage unit. This kind of memory will lose its storage content when the power is turned off, so it is mainly used to store programs that are used for a short period of time. According to the working principle of the storage unit, random access memory is divided into static random access memory (English: Static RAM, SRAM) and dynamic random access memory (English: Dynamic RAM, DRAM).
