A ramdisk is basically using memory to simulate a hard disk. Tmpfs is a filesystem that's been optimized to with a ramdisk as opposed to a physical disk backing it. Devfs is for device nodes. As you said, swap allows the kernel to page data oiut of main memory and onto the disk when main memory is getting full.
