What is Full Form of ROM, Meaning, And Definition

On this page, We are going to learn about the full form of ROM and the meaning of ROM, As well as the meaning, definition, and acronym for ROM in different categories. So you should read this post till the end.

Full Form of ROM: Read Only Memory

ROM Stands for Read-only Memory. ROM is a type of integrated circuit. It is a non-volatile memory that maintains its data even when the power is turned off. it is used in computers and other electronic devices. it is introduced in 1965 by Frederik Willem van Iterson.

ROM is a volatile or nonvolatile memory

Read-only Memory (ROM) is a nonvolatile memory. that means it retains the stored information even when the power supply is cut off.

ROM is used as an acronym to represent Read-only Memory. now you might have got some idea about the abbreviation, acronym, Full form, and meaning of ROM.

Types of Read-only Memory (ROM)

There are two types of ROM, and both have their own characteristics.

  • PROM: It is a programmable ROM and it can be modified only once by the user.
  • EPROM: In this Erasable and Programmable ROM, the information of this ROM can be erased using ultraviolet rays.
  • EEPROM: Electrically Erasable and Programmable ROM It can be erased electrically and reprogrammed about ten thousand times.

What is the Difference Between ROM and RAM?

Well, ROM and ROM both are the most important component of the computer. If you still have any confusion in understanding what is ROM and ROM memory and what is the difference between them, below.

Full-FormRAM Stands for read-only memory.RAM Stands for Random access memory.
UsesIt stores the instructions required during the bootstrap of the computer.RAM is used to temporarily store the data to be processed by the CPU.
WorkTo boot a computer, ROM is a necessary component.RAM plays an important role in CPU processing.
Permissioninformation can be read-only by the user.information and data can be written and read by the user.
Volatilityit is a type of non-volatile memory of the computer.RAM is a type of volatile memory of the computer.
Storage typeROM Stored the data permanentlyWhen the computer is turned off, the stored information and data is lost
ModificationThe data in ROM cannot be modified.The data of RAM can be modified.
Data Input ByOnly computer manufacturer companies writing information like Bios programUsers can read and write the information on the ram
Purposethe data of ROM is used to run BootingThe data of RAM is used to run the program
Storage CapacityROM is comparatively smaller than RAM.RAM has a large data storage capacity.
TypesThese are the types ROM- PROM, EPROM, EEPROM.There are two types of RAM – Static RAM and Dynamic RAM.
  1. ROM is a volatile or nonvolatile memory

    ROM is a type of Non-Volatile Memory which means ROM stores information and data permanently. you cannot erase or modify the data that is stored in it. when you restart or shut down the computer or cut the power, Still, data and information saved in ROM Chip

  2. Which memory is non-volatile memory?

    ROM memory is a non-volatile memory. it is also known as permanent memory. it is able to store data permanently.

  3. Why ROM is Non-Volatile memory and RAM is Volatile memory?

    ROM is a type of non-volatile memory because its stored information is permanent. RAM is is a type of volatile because it stores the data Temporary.
