In embedded computers, which regularly don't have disk drives, the entire expected software package can be stored in ROM. Program stored in ROM is usually known as firmware, as it is notionally more like hardware than application. Flash memory blurs the distinction in between ROM and RAM, because it retains its information when turned off but is additionally rewritable.
