ROM full form in computer
In computer ROM stands for Read Only Memory. Read-Only Memory (ROM) is a different kind of storage medium used in systems and other electronic devices which could only be read. Example contents of the memory could be read multiple times but could not be written (modified), once written.
ROM is a non-volatile type of memory, which means the information is permanently stored on the chip, therefore data in it is retained even after the unavailability of power. The memory does not depend on an electric current to save data, instead, data is written to individual cells using binary code. Non-volatile memory is used for parts of the computer that do not change, such as the initial boot-up portion of the software, or the firmware instructions that make your printer run. Turning off the computer does not have any effect on ROM. Non-volatile memory cannot be changed by users.
