VHS means Video Home System. This system uses a videocassette tape to record video and sound, which can be watched on a television. A DVD/VHS combo can record (write) on VHS tapes, read off VHS tapes, and additionally, read from DVD discs. A few can also record on DVD. VHS was so popular that during the 1990s, the terms "videocassette", "videotape", or even just "video" usually referred to the VHS format.
