The section of memory in which essential pieces of system software permanently stored. This is done during manufacturing, the computer cannot write to this area.
Computer memory whose contents cannot be changed by the user. See also OPTICAL DISK.
Computer memory in which information is stored once, usually by the manufacturer; cannot be changed
A solid-state microchip programmed at the time of its manufacture, that cannot be reprogrammed by a user. Any type of storage media that is manufactured with data in storage that cannot be reprogrammed.
A memory INC. with data stored on it that cannot be erased or rewritten by the user.
Portion of computer memory which is programmed electrically by the manufacturer, is unchangeable and is unaffected by a power loss.
(ROM) Memory chips that store data or software.
A storage location where information is permanently stored and cannot be altered.
The part of the computer's memory, containing essential operating procedures, that you can access but never rewrite.
Built in memory that permanently stores instructions and data. (The instructions and data in ROM are created when it is manufactured and cannot be changed.)
(ROM) Memory that contains programs and data that are permanently recorded when the computer is manufactured.
A memory chip from which data can only be read by the CPU. The CPU may not store data to this memory. The advantage of ROM over RAM is that ROM does not require power to retain its program. This advantage applies to all types of ROM chips; ROM, PROM, EPROM, and EEPROM.
ROM chips cannot be written to. Therefore they contain information that never changes. All PC's have ROM chips. When the PC is switched on the Information in the ROM chip is used to test the RAM. ROM does not require a constant electric supply to keep the information intact. Information in ROM is retained should you switch the PC off.
written to once (at factory or in a ROM programmer) - read many times - does not lose data when power is off
ROM is "built-in" computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off.
A microcircuit containing programs or data that cannot be erased. When new data or programs can replace old ones, the microcircuit is called an EROM, for erasable read only memory, or PROM, for programmable read only memory.
Memory chips within computers that can be read from in an instant but can never be written to. ROM memory, unlike RAM, is permanent and therefore loss of power has no affect on it.
Electronic, read only, memory which is not volatile. It does not lose its contents when power is removed. See ‘Storage devices’.
(ROM) - The portion of a computer's primary storage that does not lose its contents when you switch off the power and that contains essential system programs that neither you nor the computer can erase. A computer's startup instructions are provided by the ROM, which may contain only simple programs that tell the disk drive where to find and load the computer's operating system. But in today's environment most of the operating system is on ROM chips.
unchangeable information that is permanently stored on chips.
Data is stored permanently inside this chip. It can't be removed.
The semiconductor component of computers that cannot be changed by the user's programs because it stores programs controlling the operations of the computer.
This type of memory chip holds data and instructions permanently. A small set of instructions called the BIOS (Basic Input Output System) is stored inside a ROM chip on the motherboard.
A memory IC that has digital data on it that cannot be erased/rewritten by the user.
Memory containing a program, data, or information about the device that has been programmed onto the chip at the factory and cannot be changed. There is...
A chip that can be programmed once with bits of information. This chip retains the information even if the power is turned off. When the information is programmed into the ROM, it is called burning the ROM.
Storage space whose contents is not easily lost. There’s a lot more of it than RAM, but it’s slow. A bit of misnomer becuase (most of) it can be erased, just not as easily as you would think. Usually, ROM is truely read-only, but not in this case.
Memory that contains fixed data. The computer can read the data, but cannot change it in any way.
A memory device whose contents can be read from but not written to.
The permanent portion of the computer's memory. The contents of ROM locations can be read, but not changed. The ROM in the Commodore 128 contains the BASIC language interpreter, character-image patterns and portions of the operating system.
A chip or other electronic device that contains memory that cannot be altered.
(ROM) this stores crucial information for the start up procedure of the computer. The BIOS (Basic Input Output System) and it's settings are stored in the ROM.
Permanent memory in a computer that can be repeatedly accessed but not changed.
examples included CD-ROMS, DVDs, etc. memory storage that cannot be overwritten - just read
A computer memory read only at high speeds but not capable of being changed; compare Random Access Memory.
A type of data storage device that is manufactured with fixed contents. In its most general sense, the term might be used for any storage system whose contents cannot be altered. ROM is inherently non-volatile storage - it retains its contents even when the power is switched off, in contrast to RAM.
