What is RAM and ROM | What is the difference between RAM and ROM?
Today in this post we are computer memory i.e. ram and what is rom (what is ram and rom), type of ram and rom (types of ram and rom), ram and the difference in rom and what it has to be done described in detail.
Today in this age of technology , we are all connected to the internet through computers and smartphones and through that we complete our work digitally, but did you know that there are many hardware parts in your smartphone and your computer system, thanks to which we have all the necessary tasks to complete.
You have often noticed that while the computer or mobile phone is on, sometimes it starts running slowly or slowly and sometimes it starts to crash, as a result we have to turn off our computer or mobile phone and turn it back on again. Because sometimes the data is also lost and a lot of time is also lost by restarting again.
Do you know what is the reason for all these problems to be slow or broken? Let us know, the biggest reason for this is the RAM and ROM of your computer or mobile phone . Now let's see what are RAM and ROM (what are RAM and ROM) or what are RAM and what are their types. Let's see now one by one, what are RAM and ROM ?
What is RAM
The full form of RAM is random access memory . It is the internal memory of a computer's central processing unit where data, a program, or program results are stored. RAM is a read/write memory that stores data only for the duration of the computer's working life, i.e. it stores data temporarily .
If the light goes out while accessing memory in the system, the data in this memory disappears permanently, so RAM is volatile memory. The data can be accessed randomly in RAM but it is very expensive.
RAM is volatile memory, this means that when we turn the computer on or off, the data stored in the RAM is lost. Therefore, a UPS (Uninterruptible Power Supply) is often used to back up with a computer. RAM is smaller in terms of physical size and amount of data to be stored.
Types of RAM
- Dynamic random access memory (DRAM)
- Static random access memory (SRAM)
- rambus dynamic ram (RDRAM)
DRAM (Dynamic Random Access Memory)
The full form of DRAM is dynamic random access memory . It is a type of semiconductor memory, used specifically for data or program code required to work through a computer processor.
Dynamic RAM is a commonly used random access memory (RAM) type, used by servers , workstations and computers and used in hardware.
It consists RAM dynamic of transistors and capacitors combined. DRAM stores each bit of data in separate transistors or capacitors and has two values named 0 and 1 in one bit .
DRAM is cheaper and smaller than other RAM. Random access memory (RAM) is located closer to a computer's processor, and has the ability to access data at a faster rate than storage media (such as hard disk drives and hard drives).
Distinctive dynamic random access memory
- The data in this memory is kept for a short period of time.
- It needs to be constantly updated.
- It is slower than SRAM.
- RAM is used.
- It is small in size.
- It is cheaper.
- consume electricity.
SRAM
The full form of SRAM is Static Random Access Memory . It is the random access memory (RAM) that keeps the data in a stable form, that is, as long as there is power in the memory and it does not need to be refreshed. SRAM chips use a 6-transistor array and do not contain capacitors.
It has more space in its matrix, so SRAM uses more chips than DRAM , so the storage is equal. Thus SRAM is used as temporary memory and with its help very fast access is achieved.
Static RAM helps in accessing data faster and is an expensive memory, as many transistors are installed in each cell. SRAM does not need to be updated regularly.
SRAM is mostly recommended for these devices like – Computers, Peripherals, Printers, LCD Monitors, Hard Disk Drive, Router Buffer etc.
Premium fixed RAM
- The data remains in memory for a long time.
- No need to update.
- It arrives faster than DRAM.
- The cache is used as memory.
- Its size is larger than DRAM.
- This is too expensive.
- It consumes high energy.
RDRAM (Dynamic Rambus)
The full form of RDRAM is Rambus Dynamic Random Access Memory . It is designed to transfer data at high speed rates. RDAM consists of random access memory. It is mostly used in video game consoles, because it has a higher data transfer rate than all other types of RAM. The density of RDRAM ranges from 128 Mbit to 256 Mbit. It is also known as Direct RDRAM or Rambus.
What is ROM
The full name or full name of the ROM is ROM . ROM stores information that only memory can read but not write. ROM is non-volatile memory, which means that it stores data even when the light goes out and does not allow data to be lost.
The ROM stores these types of instructions that help start your computer and load the operating system. While the data is being created in this memory, the information is stored permanently. ROM chips are not only used in computers but also in electronic items such as washing machine, microwave, camera, mobile phone, etc.
Types of ROM
Here are the names of the following types of ROM-
- PROM (programmable ROM)
- EPROM (Erasable and Programmable Read-Only Memory)
- EEPROM (Electrically Erasable Programmable ROM)
- flash memory

The full form of PROM is a programmable read-only memory . Small amounts of RAM chips are time consuming and very expensive, which is why developers created this type of RAM known as Programmable Read-Only Memory (PROM). It is used to store permanent data in digital electronic devices and is available at a lower cost than other RAM.
EEPROM
The full form of EPROM is an erasable and programmable read-only memory . It is a special type of read-only memory (ROM) in which data can be erased and can also be used again and it is a non-volatile memory. We can also scan the data in the EPROM by high voltage UV light.
EEPROM
The full form of EEPROM is electrically programmable read-only memory . It can also be erased and regenerated using an electrical charge. EEPROM requires data to write or erase 1 byte at a time. EEPROM is used to store configuration parameters in modern computers and has now been replaced by BIOS CMOS memory in modern computers.
flash memory
Flash ROM is a type of non-volatile memory that erases data in a block unit of memory. It is more expensive than other hard drives and RAM. In this, only a limited number can be erased.
Flash memory erases the blocks stored on the flash memory chip before data is written or programmed into the microchip. Match memory almost with flash memory EEPROM, so it is sometimes called the memory of the EEPROM the Flash .
ROM Advantages
The following ROM advantages are as follows:
- It is a memory that is non-volatile in nature, which stores the program permanently.
- The data in the RAM does not change automatically, but the change itself changes the data.
- It is more reliable than RAM.
- It is cheaper than RAM.
- The ROM does not need to be refreshed frequently.
- In this, data is carefully entered, which cannot be changed again and again.
- Helps to start the computer and load the operating system.
The difference between RAM and ROM
| difference | RAM (Random Access Memory) | ROM (Read Only Memory) |
| Data holding strength | RAM is a volatile memory, it can only store data for the duration of the power supply. | ROM is a non-volatile memory that stores data even when the power is off. |
| type of employment | Data stored in RAM can also be retrieved and modified. | The data stored in the ROM can be read only. |
| Uses | Used to temporarily store normal processing data by the CPU. | Stores the necessary instructions while the computer is booting. |
| Speed | RAM is a high speed memory. | This speed is much slower than RAM. |
| CPU reaction | The CPU can access the data stored in the RAM. | Unless the data is stored in RAM, the CPU cannot access that stored data. |
| size and capacity | Bigger Capacity Bigger Size | Small size, low capacity |
| Getting started | CPU cache, base memory | Firmware and micro controller |
| Accessibility | The stored data can be accessed easily. | The stored data is not easily accessible from RAM. |
| cost | It is expensive. | Cheaper than RAM. |
| Example | DRAM ، SRAM | Concert, EEPROM, EEPROM |
