What is the Difference Between RAM and ROM?

What is RAM?

RAM is working memory that you can use to store memory temporarily. Its benefits are that it uses electricity and it refreshes its contents frequently.

We get taught about RAM (random access memory) in our computer classes. But what is RAM? It's a technology that retains data even if power is turned off.

It serves the same purpose as the infamous cookie on your browser in storing information for quick recall later when you want to open up a shopping cart in Amazon.

It also comes in handy in saving your work - whether for school assignments or videos you are editing - so that your files can be saved even when there are power outages or virus attacks.

What is ROM?

ROM stands for Read-Only Memory, which essentially makes the software unchanging. In this case, it usually refers to a type of memory in a microchip that stores permanent data even when the system is off.

The word ROM describes a type of memory that can only be read from and cannot be written to. It is mainly used in data storage such as CDs, DVDs, and USB drives.

Why do you need to know the difference between the two?

There are many reasons why it is essential to differentiate between ROM and RAM. Firstly, they are not the same thing. RAM stands for Random Access Memory and is responsible for storing data for active use by the operating system, web browsers, etc. ROM stands for Read-Only Memory and can only be read or written once with an electric charge.

How does RAM work? 

The acronym RAM stands for Random Access Memory, meaning that it accesses any cell of memory without having to move through memory sequentially.

Suppose one sector is overwritten, which starts with the first sector of information and overwrites data as it reads them sequentially until it reaches the end of the file. In that case, that sector is considered "remembered" by this type of storage.

How does ROM work?

ROM is a non-volatile memory device meaning it requires no power to maintain the data it stores. ROM, by definition, cannot be modified - the memory cannot be overwritten, and you cannot write anything new to it.

When you save something, the computer sends it into RAM, where you will then "save" that information.

What are the differences in how they store data in addition to where they store data?

1. RAM (Random Access Memory) is usually associated with volatile memory; this means it needs to be powered on to store its data, making this the type of memory where things are lost if not recently accessed. ROM (Read Only Memory) does not need power for data retention, so any data stored or otherwise fixed on it remains once it has been "burned" onto the chip.
2. As far as RAM is concerned, it is the space in which the computer processes are temporarily stored. The computer removes data from RAM when it requires additional storage or when power to that section is turned off. ROM, on the other hand, stores data that stays there permanently.
3. The one most important difference is the price of computer RAM. It's also different where they store data - ROM is stored inside a chip embedded in the motherboard, and most RAM is stored on a memory module inserted inside the computer case.

Conclusion

So I hope this tutorial will help you to learn about computer RAM and ROM.
