High Quality Good Price 4G DDR4 2400MHz MEMORY for Notebook
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 read and write at any time (except when refreshing), and it is very fast, and is usually used as a temporary data storage medium for the operating system or other running programs. When RAM is working, information can be written (stored in) or read out (taken out) from any specified address at any time. The biggest difference between it and ROM is the volatility of data, that is, the stored data will be lost once the power is off. RAM is used in computers and digital systems to temporarily store programs, data, and intermediate results.
