Computer programs and data stored in hardware - typically in read-only memory (ROM) or programmable read-only memory (PROM) - such that the programs and data cannot be dynamically written or modified during execution of the programs.

Combination of a hardware device and computer instructions or computer data that reside as read only software on the hardware device.

(computer science) coded instructions that are stored permanently in read-only memory

Computer programs and data stored in hardware - typically in read-only memory (ROM) or programmable readonly memory (PROM) - such that the programs and data cannot be dynamically written or modified during execution of the programs. See hardware and software . [78]
