WHAT IS RAM?
What is RAM Memory?, What are its types and uses..

Do you know what is RAM (Random Access Memory), then you must have heard these words very often. Whenever you go to buy a mobile and computer, then you definitely ask how much RAM is there, some people also think that if there is more RAM then there will not be a mobile hang, it will not be slow, is it true about it You will also know today in this article.

Some also believe that if RAM is always empty, then Mobile Speed ​​will run and a question comes, what is the work of RAM, you will also get the answer, with this and some things will also be talked about Primary Memory, so let's know what What is RAM and memory.

What is memory and how many types are there?

Your memory has become weak, have you spoken to someone like this, if there is no answer, but you must have told someone that your problem has become weak, then this memory is called memory. So like whatever work we want to do, we keep the work stored in a place so that as we remember it and the name of the place is mind, there is a lot of memory inside the computer, which is also called storage, Computer Memory is a place where we store data and Instruction, which we can extract data from that memory whenever we want.

So how does the computer know which data and Instruction is placed on it, then for this, the computer memory is divided into small accounts and the size of this is the same, these accounts are called Cell.

The address of each cell is known to which the Memory Address is called. And memory address means the address of the cell, Computer through this address searches the data where it is hidden (data such as your Mobile Number, Mp3, Video, File) They all live in a cell, cell address starts with 0. The number of cells in which the cell is divided is one less than its last address, for example, take a memory of 5KB and have a cell size of 1 byte, then the memory is 5 × 1024 = 5120 cells, that means the blocks will be made and so 5120 will be the address.

Although there are mainly 3 types of memory in a computer, they all have different functions and specialties.

1. Primary Memory
2. Secondary Memory
3. Cache Memory


But I will talk about Primary Memory in this article.

What is Primary Memory ?


This memory is also called Main Memory, this memory holds the same data and instruction which the computer currently uses. The space of this memory remains limited, as long as the data remains in it, as long as power means electricity remains when the data off the power disappears.

It is made of semiconductor. They have a lower speed than the registers. Whatever data and instruction remains inside the computer is processed in this main memory. Its two categories are first

1. RAM
2. ROM

What is RAM ?

The full form of RAM is Random Access Memory, it is also called Direct Access Memory. This memory remains in a low size in the computer at most times. It is less as compared to Secondary Memory like Mobile has 1GB, 2GB, 3GB, 4GB, 6GB.

So the next question comes, what is the work of RAM? Whenever you run your mobile, you play a game in it, run a lot of applications, edit, etc. For all this, the mobile needs space and it comes from the space RAM itself.

And let me take a simple example, when you play cricket, if you do not play in the bathroom, then you need more space for it, such as in the playground or street, so whenever you work in mobile all day long RAM is the memory in which all the work is done, so it is said that if the RAM is more then more applications can run simultaneously in your mobile.

What RAM does when you watch a movie or listen to a song, it resides in the song or Movie memory card, what the CPU does is take the movie out of the memory card and play the movie in RAM. The more application you run simultaneously, the more RAM will be used.

And there will be Mobile Slow or Hang up, so keep RAM as free as possible. It becomes empty when the power sieve stops inside the mobile. Well, understand that your mobile phone stops, meaning if you keep 4 to 5 Applications open in your mobile and close your mobile and turn on again, then you must have seen all your applications are closed, so this Memory is also called Volatile Memory, you know what RAM is. Now we will know the characteristics of RAM.

Why is it called Random Access Memory?

Data and instructions in RAM are stored in Cells. Each cell is made up of some rows and columns, which has its own unique address. It is also called Cell Path. CPUs can receive different data from these Cells. And that too without any sequence means that the data available in RAM can be randomly accessed. Due to its similar feature, this memory is named Random Access Memory.

What are the characteristics of RAM

You know about RAM, but you know what its properties are, you should also know.

1. RAM is Volatile Memory.

2. It is more expensive than other memory.

3. Its Capacity is less as compared to Secondary Memory.

4. Talking about speed, it is much faster than Secondary Memory.

5. This memory becomes empty when the power is turned off.

6. All Program, Application, Instruction run in this memory only.

7. CPU uses this memory.

8. It is also said to be the working memory of the computer.

Now I will tell you what are the types of RAM and what are there, there are two types.

1. Static RAM
2. Dynamic RAM


1. What is Static RAM

This is being known from the Static Sabbath, it is stable which means that the data will remain in it till the electricity comes in it. It is also called SRAM. It uses Chip 6 Transistor and no capacitor, transistors do not need power to prevent leakage. This power means Electricity.

There is no need to refersh it again and the data remains constant. SRAM needs more chips than DRAM. To store data of the same size. So SRAM costs more to build than DRAM, so SRAM is used according to Cache Memory, Cache Memory is the fastest.

Characteristic of SRAM
  • It lasts for many days.
  • No need to refresh it again and again.
  • Quite fast.
  • This is the cache used for cache memory.
  • Its size is more.
  • It is expensive than others.
  • He needs more power.

2. What is Dynamic RAM

It is also called DRAM, which is the complete opposite of SRAM. It needs to be refreshed again and again, if the data has to be maintained. This can only be possible when this memory is combined with a refresh CIRCUIT.

Most of the time this DRAM is used to make System Memory. This DRAM is made up of a Capacitor and a Transistor.

  • Characteristics of DRAM
  • This bohat lasts for a few days.
  • It needs to be refreshed again and again.
  • Is quite slow.
  • This is the cache used for cache memory.
  • Its size is less.
  • Is cheaper than others.
  • He wants less power.
What is the use of more RAM?
Think your computer is a furniture shop.

Where the CPU core is a carpenter, this means that a dual core CPU has two carpenters working simultaneously, four carpenters in a quad core CPU and so on. So the more core the better for you.

Here you can think of RAM as a workspace (which includes workbenches, tables, and other working spaces), so the more RAM there is, the more work space will be available to the "carpenters" (CPU cores) to work with. With this, they can do their work equally fast.

You can consider the hard drive as a storage area, where all the tools are kept until they are needed by the carpenter.

At the same time, due to the large work area (more RAM), the carpenter working there has to run less part in carrying his tools, so that his overall speed is more to work.

From here you must have learned how having more RAM increases both the efficiency and speed of working. Therefore, having more RAM has its own advantages, which is reflected in the performance of the computer.

Is there any difference between phone's RAM and PC RAM?

LPDDR is used in most mobile processors whereas PCDDR is used in computers.

LPDDR has full form of low power double data synchronous RAM. The PCDDR has the full form of standard Double data synchronous RAM.

These two RAMs differ in power from each other. Mobile RAM is designed to save more power, while PC RAM is designed to increase performance.

Most mobile processors are designed using ARM architecture. The PC RAM is built according to the Intels x86 architecture.

Mobile processors are primarily designed to strike a balance between performance and power, compared to PC RAM.
