ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data . Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain. Almost every computer comes with a small amount of ROM containing the boot firmware.
How do you define ROM?
Read-Only Memory (ROM), is a type of electronic storage that comes built in to a device during manufacturing . ... ROM chips come built into an external unit – like flash drives and other auxiliary memory devices – or installed into the device’s hardware on a removable chip.
What is ROM in simple words?
RAM, which stands for random access memory, and ROM, which stands for read-only memory , are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
What is ROM describe its function?
Read-only memory, or ROM, is a type of computer storage containing non-volatile, permanent data that, normally, can only be read, not written to. ROM contains the programming that allows a computer to start up or regenerate each time it is turned on .
What are the characteristics of ROM?
- You can write data only once. However, once it is written, you can read it any number of times.
- A ROM chip is used mainly in the start-up process of a modern computer.
- A ROM, non-volatile memory stores only several megabytes (MB) of data, up to 4 MB or more per chip.
What is ROM with example?
| RAM ROM | Examples: It is used as CPU Cache, Primary Memory in a computer. Examples: It is used as Firmware by micro-controllers. | The stored data is easy to access. The stored data is not as easy to access as it is in ROM. | It is costlier than ROM. It is cheaper than RAM. |

Is ROM the main memory?
Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory . It is also called as read write memory or the main memory or the primary memory. The programs and data that the CPU requires during execution of a program are stored in this memory.
What are the key differences between RAM and ROM?
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on . ROM is non-volatile memory that permanently stores instructions for your computer.
What is function of RAM and ROM?
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on . ROM is non-volatile memory that permanently stores instructions for your computer.
What are the two types of ROM?
- MROM – Mask Read Only Memory. MROM is the short form of Mask Read Only Memory. ...
- PROM – Programmable Read Only Memory. ...
- EPROM – Erasable Programmable Read Only Memory. ...
- EEPROM – Electrically Erasable and Programmable Read Only Memory. ...
- Flash Memory.
What are the three differences between RAM and ROM?
| Difference RAM ROM | Speed It is a high-speed memory. It is much slower than the RAM. |

What is RAM or ROM?
RAM, which stands for random access memory , and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
What are four types of ROM?
ROM is further classified into 4 types- MROM, PROM, EPROM, and EEPROM .
Which is faster RAM or ROM?
RAM is random access memory and cannot hold the data without the power, whereas ROM is a read-only memory and can hold the data even without the power. ... With RAM , writing data is a much faster and lightening process, whereas ROM, writing data speed is much slower as compared to RAM.
What is RAM and examples?
RAM ( Random Access Memory ) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor. ... When the computer is rebooted, the OS and other files are reloaded into RAM, usually from an HDD or SSD.
