Final answer:
A device like an external hard drive, digital camera, or memory card reader appears as another drive on the computer when connected. It allows for easy file access and management. Copying photos from a camera to a computer leaves the original on the memory card and creates a duplicate on the computer.
Step-by-step explanation:
When a device like an external hard drive, digital camera, or memory card reader is connected to a computer, it typically appears as another drive on the computer. This function allows the computer to access and manage files on the connected device as if it were an internal drive. For example, an external hard drive uses magnetic fields to encode information, which enables quick storage and retrieval of data. When it comes to digital cameras, some may connect directly via a USB cable, while others use a dock or a memory card reader to interface with the computer. Once connected, the memory card appears as a drive on the computer, which you can access by double-clicking its icon on the desktop (Macintosh) or My Computer/Computer (Windows).
Transferring photos from a camera to a computer is generally done by copying them, leaving the original files on the camera's memory card and creating a duplicate on the computer's storage. This process is facilitated by the camera or card reader appearing as another drive, making it simple to manage and share your photos.
