Final answer:
Mingji likely has a digital camera with wireless capabilities or one that works with a computer's built-in memory card reader, which allows for transferring photos without a USB cord.
Step-by-step explanation:
Mingji has a digital camera that can transfer photos without using a USB cord. Cameras like this typically have wireless capabilities such as Wi-Fi or Bluetooth, or they may use a memory card that is compatible with a built-in memory card reader in her computer. To transfer photos from such a digital camera to a computer, one would remove the memory card from the camera, insert it into the card slot provided on the computer, and copy the images from the card to the computer's hard drive.
The function of a memory card reader is to provide a connection point between a digital camera's memory card and the computer, allowing for easy access to the files stored on the memory card. Once the memory card is connected, it appears as another drive on the user's desktop environment, and files can be copied to or from it. An alternative method to share photos would be downloading them onto a computer first and then copying them onto a portable flash drive, or utilizing specialized image organizing software.
