Do you know what RAM is (), 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
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 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.
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
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 games in it, you run a lot of
applications, edit, etc. For all this, mobile needs space and it comes from
Space RAM itself.
And let me take a simple example, when you play cricket, if
you do not go to the bathroom or do not play in it, then you need more space
like 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 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 is stopped inside the
mobile. Well, understand that your mobile phone stops, that means 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 (Characteristics of RAM
in )
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, the
transistors do not need power to prevent leakage. This power means Electricity.
There is no need to refersh it again and again 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 in
It lasts for many days.
No need to refresh it again and again.
Is 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 are the benefits of having 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 known 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's RAM?
LPDDR is used in most mobile processors whereas PCDDR is
used in computers.
LPDDR has full form Low Power Double data synchronous RAM.
The PCDDR has the full form of standard Double data synchronous RAM.
Both these RAMs are different 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.
RAM in
So friends, what is RAM in today's article (What is RAM in
), how should you tell us in the comment. I hope you find this information
useful for you.
All of you must also have aimed that the RAM capacity is
increasing day by day, as a result the speed of mobile will also increase,
while you will be able to do many tasks at the same time without any lag. What
is the difference between SRAM and DRAM?
Some of my friends will have Confusion in ROM and Cache
Memory, you will also find the article in the following link. To get the best
