Differences between RAM and ROM
What is RAM?
The full form of RAM is Random Access Memory. The information stored in this type of memory is lost when the power supply to the PC or laptop is switched off. The information stored in RAM can be checked with the help of BIOS. It is generally known as the main memory, or temporary memory or cache memory or volatile memory of the computer system.
What is ROM?
The full form of ROM is a Read-Only Memory. It is a permanent type of memory. Its content are not lost when the power supply is switched off. The computer manufacturer decides the information of ROM, and it is permanently stored at the time of manufacturing, which cannot be overwritten by the user.
RAM vs ROM – What is the Difference Between Them?
Following are the Difference Between RAM and ROM
Characteristics of RAM
Here, are some essential characteristics of RAM: the volatile memory
RAM chips are widely used in the normal operations of a computer for starting and loading the operating system and applications. Much faster to read from and write Data in RAM stays there until the computer is running A RAM chip allows you to store multiple gigabytes (GB) of data. A 32 bit PC can have a maximum of 4 GB of RAM while a 64 bit PC can have 16 exabytes of RAM
Characteristics of ROM
Here, are some important characteristics of ROM memory
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
Types of RAM
Here are types of RAM:
DRAM -Dynamic RAM must be continuously refreshed, or otherwise, all contents are lost. SRAM – Static RAM is faster, needs less power but is more expensive. However, it does need to be refreshed like DRAM. Synchronous Dynamic RAM (SDRAM) – This type of RAM can run at very high clock speeds. DDR – Double Data Rate provide synchronous Random Access Memory
Types of ROM
Here are important types of ROM memory.
EPROM: The full form of EPROM is Erasable Programmable Read-only memory. It stores instructions, but you can erase only by exposing the memory to ultraviolet light. PROM: The full form of PROM is Programmable Read-Only memory. This type of ROM is written or programmed using a particular device. EEPROM stands for electrically Erasable Programmable Read-Only Memory. It stores and deletes instructions on a special circuit. Mask ROM is a full form of MROM is a type of read-only memory (ROM) whose contents can be programmed only by an integrated circuit manufacturer.
Advantage of RAM
Here, are some important advantages of using RAM
Silent: RAM does not have any moving parts, so its operation is completely silent. Power-efficient: RAM uses much less power than disk drives. Saves your system battery: It helps you to reduce carbon emissions and extend your battery life.
Advantages of ROM
Here, are some important advantages of using ROM
This memory is not lost when power is switched off. Therefore, it is called non-volatile memory. It can’t be changed accidentally Cheaper than RAMs Static and do not require refreshing

RAM vs ROM: Summary
What is the Difference Between RAM and ROM?
The difference between RAM (Random Access Memory) and ROM (Read Only Memory) is RAM is volatile. So, its contents are lost when the device is powered off. Whereas ROM stores all the application which is needed to boot the computer initially, it only allows for reading.
