Unlike hardwired machines that are restricted to a single, permanent function, a programmable machine's behavior is dictated by the software or program loaded into it.

While general-purpose computers are the most common examples of this technology, the definition broadly applies to any system that separates its hardware capabilities from its specific operational task. This includes embedded systems found in modern appliances, such as washing machines that offer multiple cycles, as well as industrial programmable logic controllers (PLCs). By using suitable programs, these devices can be reconfigured or updated to handle different inputs and outcomes, making them essential components of modern automation and flexible digital technology.
