As we all know how much memory is required to store data or information for computer or any electronic device. There are many types of memory for storage devices , one of which is ROM. 

Today we will talk about this memory in detail, and know what ROM is? What are its uses? What is the full form of ROM? What are its types? And so on. You must read the article till the end. 

What are ROMs?

A ROM is a type of memory device . It is also called the primary memory of a computer. In this, the data is permanent save. 

Some data of computer or mobile is stored in ROM, after which no changes can be made in it. Can only read in it. 

It is used only when starting a computer or mobile. They help in turning on the system. And links the BIOS with the Operating System .

Once you store data in ROM, you cannot save new data again. Its data can only be read. Guidelines related to computer functionality are stored in this memory.

ROM (Read Only Memory) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. - Wikipedia

The process which is called after opening the computer, which is called booting process, is done through this. In addition to computers, the booting process also takes place in washing machines, ovens, microwaves, smartphones, etc. Which are programmed by ROM itself.

It is a Non - Volatile memory. Data is stored forever in this permanent storage device. It is written once by the company (manufacturers). Therefore, no tampering with its data is possible.

What is the full form of ROM?

The full form of ROM is "Read Only Memory" . It is known by its name that it is a readable memory. It can only be read. No changes are possible in this. 

ROMs are used to start and boot the computer. It stores the guidelines related to the basic functionality of the computer.

ROM features?

Let us now know the characteristics of ROM.

• ROM is the primary memory of a computer. 
• ROM is also called Non - Volatile Memory. 
• Even after the power is cut, its data is not deleted. 
• It is a permanent memory device.
• It is readable memory only. 
• They are much cheaper than RAM. 
• It stores all the basic functionality instructions of the computer. 
• These are very reliable memory.
• ROMs also reduce power (energy) consumption. 

Types of ROM?

Let us now know the type of ROM. ROMs are a type of Non - Volatile memory. This means that the memory in which the data is always stored or protected, it is called permanent i.e. non volatile memory. Rome is mainly classified into three parts:

• PROM (Programmable Read Only Memory)
• E-PROM (Erasable Programmable Read Only Memory)
• EE-PROM (Electrically Erasable Programmable Read Only Memory)

PROM

PROM's full form is Programmable Read Only Memory. It is a special type of ROM memory in which a particular process programs the data suited to the users. 

Once the data or information is stored in this type of memory, it can neither be deleted nor erased. Hence it is also called One Time Programmable Device. 

After storing the data in PROM one by one, no changes can be made to it again. It consists of thousands of diodes which are fused to a high voltage and recorded as desired. Once programmed, it becomes like a normal ROM. 

E-PROM

The full form of EPROM is Erasable Programmable Read Only Memory. Its name suggests that it can be reprogram or rewrite again by erase the store data or program several times in it. 

EPROMs are like PROMs, but the only difference is that the data or programs stored in it can be erased with the help of Ultra Violet Rays and new data or programs can be stored. Hence it is also called Ultra Violet EPROM. 

EE - PROM

The full form of EE-PROM is Electrically Erasable Programmable Read Only Memory. The use of EE-PROM has increased in today's modern era. It is also called flash memory. The best example of this is Pen Drive . 

This type of ROM can be stored and deleted with the help of electric data or programs without removing it from the circuit. That is, many times data can be rewrite with the help of electric. 

This type of memory does not read the need for ultra violet ray to erase data, but can be done directly with the help of electric. This type of memory is a portable semiconductor memory, which has the characteristics of both ROM and RAM (Random Access Memory) . 

EE-PROM has the ability to protect data even under any type of anomalous circumstances. This type of electronic memory is used in many types of modern devices such as laptops, smartphones, personal computers (PCs), digital cameras, tablets (tabs), mobile phones, etc. 

Advantages of ROM?

• It is readable memory only. 
• They are much cheaper than RAM. 
• These are very reliable memory.
• It does not read the need to refresh it. 
• ROMs also reduce power (energy) consumption. 
• It stores all the basic functionality instructions of the computer. 
• Even after the power is cut, its data is not deleted. 

How does ROM work?

Let us now know how ROM works. As you may have known, ROM is an Integrated Circuit Chip that is already programmed in computer or any electronic device with various functions. 

The program or data stored in it cannot be edited or deleted again. In this, programs are stored by the company at the time of manufacturing. It is also called Firmware. A standard ROM chip cannot be rewrite or reprogramed, so its programming is very important to be completely perfect and having complete data is also very important. 

ROM is used for booting the computer while on. BIOS (Basic Input Output System) software is installed in ROM. All these works are done by the company at the time of manufacturing. 

Diode is used to turn ROM on or off, while capacitors are used to turn RAM on or off. When the computer starts or shut down, the ROM starts working, and with this help the computer boots. This means that the booting process in the computer is done with the help of ROM. 

What is the difference between RAM and ROM?

RAM	ROM
The full form of RAM is Random Access Memory.	The full form of ROM is Read Only Memory.
RAM is volatile memory.	ROMs are non-volatile memory.
RAM stores data temporally.	ROM is the Permanent Store of data.
The storage capacity of RAM is in GB (Gigabytes).	The storage capacity of ROM is in MB (Megabytes).
Data access speed of RAM is fast.	The speed of data access of ROM is slow.
RAM is used to run programs in computer or mobile.	The function of ROM is to store the data present in the device.

So friends, you must have known everything about Rome now. What is ROM? Types of ROM? Full Form of ROM? And so on. You will now have full knowledge of Rome.
