abstract
If the computer boot shows that the memory size is reduced and the machine is restarted repeatedly, it means that there is a problem with the memory and it needs to be replaced to solve the problem.
Memory is the storage part of a computer, which is used to store original data, intermediate results and programs that instruct the computer to work.
Memory can be divided into random access memory (RAM) and read-only memory (ROM). The former allows reading and writing data, and the programs in the disk can only run after being transferred to RAM. The CPU can directly access the RAM and exchange data with it. When the computer is turned off, the information in the RAM will be lost. The information behind can only be read, not written at will, and will not be lost even if the power is cut off.
