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.
| Basic | ROM | RAM |
|---|---|---|
| Full-Form | RAM Stands for read-only memory. | RAM Stands for Random access memory. |
| Uses | It stores the instructions required during the bootstrap of the computer. | RAM is used to temporarily store the data to be processed by the CPU. |
| Work | To boot a computer, ROM is a necessary component. | RAM plays an important role in CPU processing. |
| Permission | information can be read-only by the user. | information and data can be written and read by the user. |
| Volatility | it is a type of non-volatile memory of the computer. | RAM is a type of volatile memory of the computer. |
| Storage type | ROM Stored the data permanently | When the computer is turned off, the stored information and data is lost |
| Modification | The data in ROM cannot be modified. | The data of RAM can be modified. |
| Data Input By | Only computer manufacturer companies writing information like Bios program | Users can read and write the information on the ram |
| Purpose | the data of ROM is used to run Booting | The data of RAM is used to run the program |
| Storage Capacity | ROM is comparatively smaller than RAM. | RAM has a large data storage capacity. |
| Types | These are the types ROM- PROM, EPROM, EEPROM. | There are two types of RAM – Static RAM and Dynamic RAM. |
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
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.
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.
