What does ROM stand for?

Read-Only Memory is a type of non-volatile storage that is traditionally used in computers and electronic devices. This memory retains its data even when the device is powered off, making it essential for storing firmware, which is critical software that initializes hardware during the boot process. Unlike RAM (Random Access Memory), which is volatile and loses its data when power is removed, ROM is specifically designed to be read from but not easily modified or written to. This characteristic makes it secure for preserving important system instructions and data that should not change frequently.

The other options refer to concepts or terms that do not align with standard definitions of memory types used in computing. Understanding ROM is fundamental in principles of computer architecture and memory management, highlighting its role in the functioning of various electronic devices.
