what the difference between ROM and RAM ? -> RAM (random access memory) and ROM (read-only memory) are both present in your computer.

RAM is a type of volatile memory that holds the data you’re working on briefly. ROM is a type of non-volatile memory that holds instructions for your computer indefinitely.

what is the ram and rom ?

Both RAM and ROM are forms of computer memory. RAM is a type of memory that is used to store computer programmes and data that the CPU requires in real time. RAM data is volatile, and it is wiped when the machine is turned off. The ROM contains pre-recorded data that is utilized to boot the computer. RAM data is static, meaning it stays in the computer even after the machine is turned off.

Random Access Memory (RAM) is used to store the programmes and data that the CPU uses in real-time. The data in random access memory can be read, written, and deleted indefinitely. RAM is a physical component that stores the data that is presently being utilised. It’s a short-term memory. RAM Varieties:

A Read Only Memory (ROM) is a sort of memory in which the data has already been recorded. Data saved in ROM is non-volatile, meaning it is preserved even when the computer is shut off. ROM Types:

Types of Ram

  • Static RAM, often known as (SRAM), is a kind of memory that stores a bit of data by utilising the state of a six transistor memory cell.
  • Dynamic RAM (DRAM) is a type of memory cell that stores bit data utilising a pair of transistors and capacitors.

Types of Rom

  • Programmable ROM, in which the data is written after the memory chip has been constructed. It is non-volatile.
  • Erasable Programmable ROM, in which the data on this non-volatile memory chip may be wiped by exposing it to high-intensity UV radiation.
  • Electrically Erasable Programmable ROM, in which the data on this non-volatile memory chip may be electrically wiped via field electron emission.
  • Mask ROM is a type of memory chip in which data is written while the memory chip is being manufactured.

Retention of data

  • RAM is a volatile memory that can store data as long as power is applied.
  • ROM is a type of non-volatile memory that can preserve data even after the power is switched off.

Type of work

  • RAM data may be retrieved and modified.
  • Only data saved in ROM may be read.


  • Used to temporarily store data that must be processed by the CPU at the time.
  • It holds the instructions needed during the computer’s bootup process.


  • It is a memory with a high speed.
  • It is significantly slower than RAM.

Interacton with the CPU

  • The CPU has access to the data that is stored on it.
  • The CPU cannot access the data stored on it unless it is in RAM.


  • It is more expensive than ROM.
  • It is less expensive than RAM.

what Ram and Rom type

  • DRAM (Dynamic Random Access Memory) and SRAM (Sequential Random Access Memory) are two types of memory (Static Random Access Memory).
  • PROM (programmable read-only memory), EPROM (erasable programmable read-only memory), EEPROM (electrically erasable programmable ROM), and Mask ROM are the several types of programmable read-only memory.

What ROM and RAM are used in a variety of ways.

A ROM chip is utilised largely during a computer’s startup phase, whereas a RAM chip is used during routine operations once the operating system has been installed. A ROM chip, for example, is frequently used to store the BIOS programme on the motherboard. A RAM chip on a computer temporarily stores files in use, such as a paper you’re composing, a picture you’re editing, or gaming data.

ROM (Read-Only Memory)
The computer BIOS, which is a PROM chip that holds the programming needed to initiate the first computer starting process, is an excellent example of ROM. For computers and other devices, the only method to start this process is to use a non-volatile storage media. ROM chips were also utilised in the original Nintendo, Gameboy, Sega Genesis, and other game system cartridges.

Computer RAM is used in computers and other devices to swiftly store temporary data generated by applications. RAM is one of the quickest memory kinds, allowing it to transition between jobs quickly. The Internet browser you’re using to read this page, for example, is loaded into RAM and runs from it.
