Difference between ROM and RAM

Main Difference between ROM and RAM

For a computer system to function, there is always a requirement for memory and critical files to be stored on the system. This can be done with the help of storage devices and options that can help to read the data on the storage devices. This can be done in two ways for digital devices in the form of ROM and RAM. Both are known as read-only memory and random access memory, respectively. They both have differences between them. The main one is that RAM stores memory for a short period of time and when the system is shut down, data is lost. ROM, on the other hand, stores data forever. Changes can be made to the data in RAM, but such changes cannot be made to the data in ROM. This helps to make the observation that ROM data is only available in read mode, while RAM data can be read and written according to requirements. RAM is available in two different types, while ROM has 4 other forms, all of which are used in the system according to specifications. There are also many other minor differences that will be discussed at the end.

ROM is known as read-only memory, which is used in digital devices such as computers and cell phones. It is used to properly store memory that cannot be changed quickly and requires certain actions for modifications to take place. All applications and drivers are installed in ROM because it can keep memory safe and for longer. Once the product is manufactured there can be no changes to the system hardware and the specifications it has because they are completely stored in ROM. Although this can have its benefits, there are also some drawbacks, for example if there are some bugs that hinder the process or errors that need to be debugged, they cannot be removed and the problem persists. Because of this,

RAM is known as random access memory and it is a different way of storing data than ROM. The main advantage of this is that the data can be used in a short time, since it is available for reading at any time. RAM maintains the location of data in memory and every time the command requests it, it brings that memory back to the user. In the past, devices such as hard drives and battery memories were used to perform this task and the system took much longer to operate. It operates on the principle of multiplexing and demultiplexing that helps to get to the line where the data is stored for reading and writing. It can divert the user to different locations and memories at the same time, which is another advantage it has over previous devices. The only disadvantage is that if the system shuts down or some other error occurs, the data that is written will be lost. Efforts are being made to reduce this problem, but much work remains to be done in this regard.

Differences in a nutshell

  1. RAM is known as random access memory, while ROM is known as read-only memory.
  2. RAM allows the user to read and write data, while ROM only allows the user to read data.
  3. The RAM can run different applications that are installed on the computer, while the ROM helps to maintain the main files of the application that were installed.
  4. ROM has all the critical files needed to boot the system, while RAM does not hold any of those files.
  5. Data stored in ROM is safe and cannot be altered, data stored in RAM can be lost the moment the system is shut down.
  6. RAM can be accessed easily at any time, while ROM cannot be accessed all the time.
  7. RAM alterations can be made, but ROM changes cannot be made effortlessly.
  8. The main types of RAM include RAM and DRAM, while the main types of ROM include PROM, EPROM, and EEPROM.

Conclusion Difference between ROM and RAM

Computer architecture is something that is a mystery to people who are general users and do not have detailed knowledge of it. The two terms ROM and RAM are similar which are considered the same but are different in operation and functions. This article, therefore, provides a proper understanding of the two types so that people have a clearer idea.
