That is, the mass storage device 607 may include a computer device readable medium (not shown) such as a hard disk or Compact Disc-Only Memory (CD-ROM) drive.

Without loss of generality, the computer device readable media may comprise computer device storage media and communication media. Computer device storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer device readable instructions, data structures, program modules or other data. Computer device storage media includes RAM, ROM, Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), CD-ROM, Digital Video Disk (DVD), or other optical, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices. Of course, those skilled in the art will appreciate that the computer device storage media is not limited to the foregoing. The system memory 604 and mass storage device 607 described above may be collectively referred to as memory.

The computer device 600 may also operate as a remote computer device connected to a network through a network, such as the internet, in accordance with various embodiments of the present disclosure. That is, the computer device 600 may be connected to the network 612 through the network interface unit 611 coupled to the system bus 605, or may be connected to other types of networks or remote computer device systems (not shown) using the network interface unit 611.

The memory further includes one or more programs, the one or more programs are stored in the memory, and the central processing unit 601 implements all or part of the steps of the method shown in fig. 2 or fig. 3 by executing the one or more programs.

Those skilled in the art will recognize that, in one or more of the examples described above, the functions described in embodiments of the disclosure may be implemented in hardware, software, firmware, or any combination thereof. When implemented in software, the functions may be stored on or transmitted over as one or more instructions or code on a computer-device-readable medium. Computer device readable media includes both computer device storage media and communication media including any medium that facilitates transfer of a computer device program from one place to another. A storage media may be any available media that can be accessed by a general purpose or special purpose computer device.
