             1. RAM (Random Access Memory)

                 ① Used to read and write data.

                 ② Go to Setting > Apps > Running to check RAM.
 
             2. ROM (Read Only Memory)
                 ROM is the memory storage that maintains stored data without any external power source.
                      It plays the role of HDD in a computer. 
                 ② Please go to Setting > Storage > Internal Storage > Available. 
                 ③ Apps are stored in ROM. As smaller the ROM, the less apps can be stored. To write more data, a external SD card has to be used.
                      To manage your memory space, go to Menu > Settings > Apps > select the App > Uninstall

                      or move to the SD card to manage memory.

                       Some apps may not be stored in the SD card.
