It allows you copy, byte by byte, from a device to another device. I
usually use it to make images of CDROM disks (data disks, not audio
disks). Assuming my cdrom device is /dev/cdrom and I want to make it's
image as cdimg.iso, I use this command:
$> dd if=/dev/cdrom of=cdimg.iso

Do "man dd" for more info.
