What is RAM, what are its types and uses?

Do you know what RAM is (Hindi), 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 it, 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 get the answer also, with this and some things will also be talked about Primary Memory, so let's know what What is RAM in Hindi and memory?

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 that work in a place so that as we remember it and the name of the place is the 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.

What is Internet and who owns it

What is a firewall and why is it important

What is GPU? What's the difference between GPU and CPU

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 from 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
