What Is Memory Usage on Windows?

Memory, which should be exactly RAM (Random-access memory), is an important component of a computer. A RAM device allows data to be read and written at any time, regardless of the physical location of the data within the memory, and the read and write speed is very fast normally.

The data stored on the RAM device is temporary. After you shut up your computer, the memory usage will be 0 (zero). However, as long as you open your PC, the background services and running apps will begin to use the memory. The percentage of memory usage will influence the performance of your computer. If the percentage is too high, your computer performance will be reduced. So, Windows memory usage is a matter of concern.
