To ensure that your Windows 10 PC can store information temporarily or permanently, the computer memory is an indispensable physical device. The computer memory consists of the Cache, RAM (random access memory), and ROM (read-only memory).
It empowers the computer CPU to access instructions and data at a blazing fast speed. You can find the relationship between RAM and ROM in this article: What Is Computer Booting?
The memory is used so as to store the operational data of the CPU temporarily and the data exchanged with external memory (for example, a hard disk).
In other words, the CPU can transfer the data that needs to be operated into the memory for operation, and then transmit the result out when the operation is finished.
Furthermore, the program installed on the HDD is loaded into memory for running. Undoubtedly, the main memory is an important factor that determines your computer’s performance and stability.
