(3) (Hard Disk, Hard Drive) For example, a 500GB HD is a 500 gigabyte hard disk. FD means floppy disk; now a distant memory. See hard disk, magnetic disk and floppy disk.

(4) (High Density) HD and DD (double density) were used in floppy disk designations. For example, 3.5" 1.44MB HD and 720KB DD or 5.25" 1.2MB HD and 360K DD. See floppy disk.

(5) (High Definition) A screen resolution of 1280 x 720 pixels. HD+ is 1480x720. See DTV, FHD, 720p and screen resolution.
