Question

A memory that holds micro programs is ____________.

• A. Core memory
• B. ROM
• C. RAM
• D. Control memory
• E. None of the above

Answer 1

The correct option is B ROM

A memory that holds micro programs is ROM.

Machine language interprets and sends machine instructions to the lowest hardware layer level where they are translated into small micro programs called microcodes. Microcode is stored in the ROM or in the erasable programmable ROM (EPROM) and cannot easily be modified by generic programmers.

Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to store firmware (software that is closely tied to specific hardware, and unlikely to need frequent updates) or application software in plug-in cartridges.
