Ram and Rom (What’s Difference Between)

RAM, short for random access memory, and ROM, short for read-only memory, both exist in computers. RAM is volatile memory that temporarily stores files you are working on. ROM is a non-volatile memory that permanently stores computer instructions.

Difference between RAM (Random Access Memory) and ROM (Read Only Memory)

Below is a detailed explanation of the difference between RAM (random access memory) and ROM (read-only memory). RAM is a form of computer memory that can be read and modified in any order and is commonly used to store working data and machine code.

ROM is a type of permanent memory used in computers and other electronic devices. The difference between RAM and ROM will help you better understand the basics and compare them thoroughly.

The major differences between RAM and ROM are:

The definition of RAM is Random Access MemoryThe definition of ROM is Read-only Memory
Random Access Memory (RAM) is expensive when compared to ROMROM is cheaper when compared to RAM.
The speed of Random Access Memory (RAM) is higher when compared to ROMThe speed of Read-only Memory (ROM) is slower when compared to RAM.
Random Access Memory (RAM) has a higher capacity when compared to ROMROM has a lower capacity compared to RAM
Data in RAM can be modified, erased, or read.Data in ROM can only be read, it cannot be modified or erased.
The data stored in RAM is used by the Central Processing Unit (CPU) to process current instructionsThe data stored in ROM is used to bootstrap the computer.
Data stored on RAM can be accessed by the Central Processing Unit.If the Central Processing Unit (CPU) needs to access the data on ROM, first the data must be transferred to RAM, and then the Central Processing Unit (CPU) will be able to access the data.
Data of RAM is very volatile, it will exist as long as there is no interruption in power.Data present in Read-Only Memory (ROM) is not volatile, it is permanent. Data will remain unchanged even when there is a disruption in the power supply.

These are the main differences between RAM and ROM. The differences given in the above table can help the UPSC Civil Service Exam aspirants to answer any related questions easily in the exams.

What is the main difference between RAM and ROM?

RAM is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. ROM is a type of non-volatile memory used in computers and other electronic devices.

What are the 2 differences between RAM and ROM?

Data stored in ROM is retained even after the computer is turned off ie, non-volatile.

SpeedIt is a high-speed memory.It is much slower than the RAM.
CPU InteractionThe CPU can access the data stored on it.The CPU can not access the data stored on it unless the data is stored in RAM.

What is the difference between RAM & ROM give examples of each?

ROM stands for read-only memory. It is a non-volatile memory that stores information permanently, even when the power is turned off.
What is ROM:

Examples: It is used as CPU Cache, Primary Memory in a computer.Examples: It is used as Firmware by micro-controllers.
