What is RAM and how It Works


First, we know that what is Ram and how it works. For understanding this we have to mind that whenever we buy a new computer or mobile so our first question to the shopkeeper is that how much RAM is there.

Because it is an important part of our mobile. On which the speed and performance of mobile and computer depends?

But have you ever wondered what is Ram, and how the speed of Mobiles is increased?

Normally everyone says about Ram that keeping the mobile Ram only makes the mobile run fast and doesn’t even hang.

But have you ever thought that how does RAM increases the speed of our mobile? And why the mobile does not hang due to keeping the RAM free?

So in today’s post, we discuss what is RAM? Types of RAM and how does it work?

Know first that RAM is a memory. So first of all we know what is memory?

What is and how many types of memory?

Computer memory is that part of the computer. Where we can store data and instruction. That is, memory provides the facility of information storage.

If there is no memory in the computer, then we will not be able to save and keep any data in the computer.

Just like we need the brain to remember anything. Similarly, the computer also needs memory to save the data.

Computer memory is divided into small parts. Which we call cells. And each cell has a different cell address. In these cells, data is stored in binary numbers (0-1).

The computer has two types of memory one is primary memory and the second is secondary memory.

What is and how many types of primary memory

This is the main memory of the computer. Primary memory is part of the CPU (Central Processing Unit) of the computer. It is also called internal memory.


This memory would store the running programs or their input and output data for some time. When the computer is powered off or the power supply is turned off, all the data stored in it gets deleted.

Simply put, it stores memory data only when the computer is in a running state.

The size of this memory is small. But its speed is very fast. RAM and ROM are the main two types of primary memory.

Random Access Memory is called in short the RAM. This memory is made of a metal oxide semiconductor (MOS) in a chip form.


This is a volatile memory. The data stored in this is temporary. That is, on powering the PC or Shut Down. All the data stored in is destroyed.

It is of a lesser size in computer and mobile. Like 2GB, 3GB, 4GB, 6GB or 8GB. When we run any program on our computer.

So the program is run on the computer memory inside the RAM by the CPU whatever work we do RAM is used for that. Now you must have understood that what Mobile RAM is.

How many types of RAM are there?

Usually, Ram is of two types. SRAM and DRAM.

SRAM (Static RAM)

Static Random Access Memory i.e. is the full name of SRAM. It is not refreshed again and again. In this, the data remains stored till then. As long as the power of the computer will remain on.

It accesses the data very fast. It is also known as Cash Memory. DRAM is cheaper than SRAM. And produces more heat than DRAM.

DRAM (Dynamic RAM)

Dynamic Random Access Memory is the full form of DRAM. It is cheaper than SRAM. Because its speed is very slow. And it is also cheaper than SRAM. And it gets less heat.

This RAM is used in most computers and mobiles. Due to being volatile memory, the data remains in it only till the power is on.

What is RAM and how It Works

This question must have also come to your mind that how does this RAM work? What differences are made on the performance of our mobile and laptop? So let’s know about the function of RAM.

Whenever you play a game on your computer or mobile or open any software or application or watch a movie. So your mobile reads the need for space separately. Where all this can be done.

Like when you play a game on your mobile, then the game is already saved in the memory. CPU brings it to RAM and then the game is played and is stored in RAM till we play it.

You must have seen many times that when you open many applications in your mobile simultaneously and after locking the mobile, all the applications get closed.

This is due to RAM being Volatile Memory. When the RAM of your system is more, there will not be much load on the CPU. This will keep the speed of your system fast.

Till now you know what is RAM, the types of Ram, and what is the meaning of Ram? We must have understood this, that how much RAM is necessary for our mobile or computer.

Friends, how much should be the RAM of mobile, you have to decide yourself on what is the purpose of keeping mobile.

If you need to run more software for gaming or more. You will need more RAM.

Suppose you have a mobile or laptop for normal work then your work will run even with less RAM.

As the more RAM of your computer, the more you will be able to do multitask and the speed of the system will also be faster.

If my opinion is asked then I will tell that there should be at least 4GB RAM. Because some RAM covers the system apps already in it.

Nowadays, applications and software are also in much larger sizes. When you required fast performance, you should go for 6GB or 8GB RAM.


Friends, I hope that what is RAM, full information about RAM, and types of Ram, you have understood.

Have any questions in your mind please must comment? And this general information about RAM is important for everyone.

So please share this post with your friends. So that they can also get information about the RAM of the phone they are using daily.
