RAM (Random Access Memory) and ROM (Read Only Memory) are two main types of memory of a computer. As you know that without these two things we can’t run a computer.
The main difference between RAM and ROM is that the data in RAM is not stored permanently whereas in ROM the data is stored forever even when the computer is turned off.
The process of scripting data in ROM is very slow, but in RAM it is much faster compare to it. The RAM stores data in Gigabytes (up to 16 GB) and the ROM stores data in Megabytes (Up to 4 MB).
RAM is volatile memory, the data in RAM got lost when the computer is power offed, but the ROM is non-volatile memory, the stored data in ROM is re-accessible even after the computer is turn off.
Nowadays, in devices like Smartphones and Tablets, the ROM is referred as the internal memory (also called as internal storage) which is used for storing Apps and its data.

Normally, RAM is a replaceable chip, we can easily plug or unplug the RAM but, ROM is inbuilt, it is irreplaceable.

Features And Differences between RAM and ROM
Below I have differentiated RAM and ROM, the below table is useful for quick information, and also it will help you in your academics.

1. It’s full form is Random Access Memory
2. The data in RAM is accessible at any time from any location.
3. The performance of RAM is faster.
4. It stores all the data external data and allow us to run Apps.
5. It is volatile memory. The data get lost when the computer is turned off.
6. There are 2 types of RAM, Static RAM and Dynamic RAM

1. It’s full form is Read Only Memory.
2. As the name suggests, the data in ROM is read only, we can’t manipulate the data of it, actually it’s very hard to do that.
3. The performance of ROM is bit slower compare to RAM.
4. It only collects the important data which is require is to boot up the computer.
5. It is non-volatile memory, the data get saved permanently and doesn’t get lost even if the computer is turn off.
6. There are mainly 3 types of RAM, EPROM, Erasable ROM and Programmable ROM.

Why RAM is faster than ROM –
If you have read the introduction paragraphs than you may be questioning why RAM is faster ROM. RAMs are bigger compared to ROMs than that is the most major reason why it works faster than ROM.

When RAM and ROM works –

RAM and ROM are the essential parts of the computer, and both play a significant role. When you turn on the computer, you can black or blue screen with some complicated text, during this time the ROM takes data from hard disk and display it on the screen, this is when the ROM works. The ROM control the computer for few seconds when your turn it on. Thus, the ROM stores the BIOS of the computer.
Once the computer is on, the operating system gets read from hard disk and loaded in ROM. When you open any App or game that get loaded into RAM. That’s it is recommended to use RAM of much GBs.

Ending the Article –

At the end of the article, I have to say that the differentiation provided above related to RAM and ROM. If you follow the above provided instructions and guide properly, then you will easily understand the whole concept of RAM and ROM. From there working to differences and also about their working structure.
Everything will be cleared till the end of the article.
Their working and their differentiation of both RAM and ROM is the most prominent part of the whole guide and even of their existence. Those two concepts are highlighted in the guide to give you guys a proper idea about the whole concept.
