The difference between mobile phone memory and SD card

Any mobile phone has memory, which is generally divided into two parts.

The phone comes with its own memory.

Part of it comes with the mobile phone, and this part is relatively small. This part of the memory is considered by mobile phone manufacturers to be unchangeable, and it can simply store SMS and MMS.

Sd card

The other part is the SD card. This part depends on how old you use it. You can buy it yourself. It should be noted that when selling, you need to pay attention to the maximum SD card capacity supported by the mobile phone. It's no use buying after it's exceeded.

The difference between mobile phone memory and computer memory

The memory of a dedicated mobile phone is completely different from that of a computer. The memory of a mobile phone is completely different from that of a computer in general. The information in the mobile phone memory will not disappear when the power is cut off, and the information in the computer memory will also disappear. So the memory of the mobile phone should actually be close to the hard disk of the computer.
