A computer memory chip that stores values but does not allow updates, in which the values are nonvolatile in that they are retained even when the computer is unpowered
Memory whose contents the computer can read, but cannot change Information is placed into ROM only once, during manufacturing
Abbreviated ROM; computer memory or storage that can be read but not written to by the user ROM is created at the time of computer chip, card, or disc manufacture and is used to store the computer's essential system programming or other non-changeable data
Semiconductor-based memory that contains instructions that can be read but not modified
(computer science) memory whose contents can be accessed and read but cannot be changed
Memory that includes permanent information only The computer can only read information from it; it can never write any new information on it
Permanent memory, not user-programmable The Courier V Everything modem's factory settings are stored in ROM and can be read (loaded) into RAM as an operational configuration if DIP switch S10 is ON at power on
A storage area in which the contents can be read but not altered during normal computer processing
Memory in which stored data cannot be modified by the user except under special conditions
Nonvolatile primary storage; ROM holds the instructions that a computer uses when it is first turned on
Memory that can be read only and remains after the power is turned off Non-volatile memory
ROM A computer's unchangeable memory It's used to store programs that start the computer and run diagnostic functions
A semiconductor memory whose data cannot be erased, or overwritten; it can only be accessed (read) for use by the CPU The data in a ROM is of a permanent nature and is programmed by the ROM manufacturer In many cases, its programmed information identifies the dedicated function of a computer A ROM can also be in the physical form of a module (tape or disk) that is plugged into a computer to change its operation from one program to another
