A DMG file is essentially a disk image file that's commonly used on Macs, it's like a virtual container that holds the contents of a disk. These files are often used to distribute software, so if you've downloaded a program for your Mac, it might be in a DMG file. To open it, you'll need a Mac, as DMG files are specific to macOS, although some third-party tools can also open them on Windows or Linux. If you're on a Mac, just double-click the file and it should mount as a virtual disk, allowing you to access its contents.
