The invention discloses a
memory box. The
memory box comprises a shell, a PCBA board and a hard disk. The shell is provided with an interface connected with the PCBA board. An interface at least comprises a power interface, a
digital multimedia interface and a plurality of
USB interfaces. The PCBA board comprises a main control module, a
random access memory, a read-only memory, a
bus interface, apower management module, a
wireless communication module and a
wired communication module. The main control module is integrated with the power supply interface, the
digital multimedia interface, theplurality of
USB interfaces, the
bus interface and the power
supply management module. The
wireless communication modue and the
wired communication module are integrated and connected to the PCBA board, and the
bus interface is respectively connected with the
random access memory, the read-only memory and the hard disk in series. The PCBA board is connected with the housing interface. The power interface is connected with a power supply source, the multiple
digital multimedia interfaces and an externally-conencted intelligent terminal for the
USB interfaces. Through circuit connection of PCBAs, the intelligent terminal is connected with one P2P distributed private cloud through internet so as to be provided for the intelligent terminal to complete storage or calculation of pictures or files.
