What is RAM?

RAM is a type of memory that temporarily stores programs or software running on a computer. This means that RAM stores it as long as the computer is running or as long as the software is running. And once the computer is turned off, all the data stored in it is automatically deleted.

RAM is used to read or write data. It is a high speed semiconductor memory attached to a microchip.

RAM is a portion of primary memory that is accessed directly from the CPU, hence it is also called direct access memory.

RAM is a type of temporary memory. This means that once the computer’s power supply is cut off, all data stored in RAM is erased.

RAM storage capacity is lower than secondary memory, but much faster. All programs running on the computer and their data are run and stored only in RAM.

For example, suppose you are creating a presentation file on a computer using MS PowerPoint. And you have prepared 10 slides, but you have not yet saved this presentation file to your hard disk.

So tell me now, where are these files stored on your computer? Basically in this case the file is stored in RAM. And as long as PowerPoint is open, or as long as your computer is running, it will be stored in RAM.

If you suddenly lose power while working, all your data will be lost if your computer shuts down. And all your hard work will be in vain.

Therefore, it is always advisable to use UPS (uninterruptible power supply) when using desktop computer systems. And from time to time keep saving your work on the hard disk.

What is the full form of RAM?

The full form of RAM is “Random Access Memory”. RAM plays a very important role in computers and smartphones. Without RAM we can’t do anything on computers and smartphones.

Because the app or software we work on is stored in temporary memory, that is, in RAM. At the same time running more programs or software makes mobile or computer work slower, due to less RAM storage.

History of RAM

RAM was first used in computers in the 1940’s. Magnetic-core memory was dependent on an array of magnetic rings. Data was stored by magnetizing each ring. Each ring contains a single bit data store and indicates that the magnetization direction is zero or one.

Technological advances allow devices to store more data as they get smaller, but they still operate on the same principle.

The real breakthrough for computer memory came in the 1970’s with the invention of solid-state memory in integrated circuits. It used very small transistors, which made it possible to store a lot of data in a very small area.

In the early 1990’s, clock speeds were synchronized with random access memory.

SDRAM quickly reached its limit, as it transfers at a single data rate.

In the early 2000’s, Double Data Rate Random Access Memory (DDR RAM) was created. It can transfer data twice as fast as one hour cycle. The introduction of DDR RAM has also changed the definition of SDRAM, as many sources now define it as single data rate RAM.

DDR RAM has evolved three times, via DDR2, DDR3 and DDR4. Data speed and low power have been used with each iteration. However, not every version is compatible with the previous one.

Features of RAM

Let’s know some features of RAM.

  • RAM is the primary memory of a computer.
  • RAM is also called volatile memory.
  • RAM is direct access memory.
  • Its storage capacity is less than that of secondary memory.
  • When the power goes out, this memory becomes empty, that is, all the data in the memory is erased.
  • The speed of RAM is higher than that of secondary memory.
  • All programs, apps, software, etc. only run in RAM.
  •  It is also called the working memory of the computer.
  • This memory costs a bit more than other memory.

How many types of RAM

There are two main types of RAM. RAM is designed according to the different sizes of computers and laptops. And its size is very small in mobile.

The speed of RAM is measured in MHz and GHz and its storage capacity is measured in MB and GB.

Desktops, laptops, smartphones, tablets, etc. all have RAM, but different types of RAM are used in each device. So we can’t use laptop RAM on desktop or mobile RAM laptop.

This is because RAM is divided into different types according to size, speed and capacity. There are two main types of RAM

  • Static RAM or SRAM
  • Dynamic RAM or DRAM

Static RAM or SRAM

The full name of SRAM is Static Random Access Memory. Static means “constant”, meaning that data will be stored in the computer as long as electricity flows through it. Once the computer loses power, all the data stored in it is erased and the RAM is completely emptied.

There is no need to refresh the computer repeatedly. Because it keeps the data stable. Static RAM is also called SRAM.

Static RAM consumes less energy and works much faster than dynamic RAM. It has low storage capacity and high production cost.

  • Data is stored in RAM as long as the power supply is on.
  • It is a volatile memory, its data is lost when the power goes out.
  • SRAM uses a 6-chip-transistor matrixIt does not use any capacitors.
  • It uses more chips than DRAM.
  • It costs more to makeIt is used as cache memory.
  • It works faster than DRAM.
  • It consumes more electricity.

Dynamic RAM or DRAM

DRAM stands for Dynamic Random Access Memory. Dynamic RAM is the exact opposite of static RAM. These are not static, they are constantly changing, hence the name dynamic.

Dynamic RAM is also temporary memory, which also loses all data when power is lost. This is also known as DRAM.

To keep data safe, that is, to store it in DRAM, it needs to be refreshed repeatedly. Its capacitors, which store data, gradually lose power.

If the power is then discharged, all the data stored in it is deleted. It has more memory capacity but less speed.

  • It is frequently refreshed to retain data.
  • It is cheaper than SRAM.
  • It is commonly used as system memory.
  • It is made up of memory cells that have a transistor and a capacitor.
  • Its lifespan is less than SRAM.
  • It works at a lower speed than SRAM.
  • It is used as RAM.
  • It also consumes less electricity.

There are three types of DRAM or Dynamic RAM:

  • SDRAMRD
  • RAMDDR
  • SDRAM

DDR SDRAM again comes in many forms

The difference between RAM and ROM

Ram Rom
The full form of RAM is Random Access Memory. The full form of ROM is Read Only Memory.
RAM is volatile memory. ROM is non-volatile memory.
RAM temporarily stores data. ROM saves data permanently.
The speed of accessing RAM data is fast. Slow to access ROM data.
RAM is the primary storage ROM is secondary storage
Prices are relatively low. The price is relatively high.
RAM’s job is to run programs on computers or mobiles. ROM’s job is to permanently store the data on the device.
Data stored in RAM can be read and written Data stored in ROM can only be read
Types of static radham, dynamic radham, etc. radham. PROM, EPROM, EEPROM etc. are the classification of ROM

How RAM works

Random access memory is the most important part of computer memory. The reason we call it random access memory is that if you know the intersection of cell rows and columns, you can easily access any of its memory cells.

RAM memory cells are made up of many transistors and capacitors. Memory cells store data by these two binary digits 0 and 1. 1 when data is recharged and 0 when discharged. This is done through the memory controller. RAM’s job is to bring the software you want to use from the hard disk and run it on your computer according to the instructions. However, we cannot give any instructions directly to RAM, the CPU gives instructions to RAM. Suppose you click to open Mozilla Firefox browser on your computer. Now the processor will first instruct RAM to open it, then based on that instruction RAM will load Mozilla Firefox data from hard disk into its own and launch the browser.

When the mobile phone or computer is off, the RAM does not work at all. At that time the apps and software that we have are stored in the memory of the phone or hard disk or memory card.

But whenever we turn on the computer, the operating system loads first. After that we can open other software or apps.

RAM or Random-Access-Memory (random access memory) is a much needed hardware for computers and smartphones without which computers and smartphones are not self-contained, or usable. Its function is to memorize or store information about the ongoing work of the device for a certain period of time. As if the processor does not have to process the same information over and over again. There are many misconceptions about RAM in humans. And so today’s article is to give a clear idea about RAM.

In fact, how much RAM you need

If you are a 32 bit Windows user, you can use up to 4 GB RAM because 32 bit Windows does not support more than 4 GB RAM, even if you use 8 or 16 GB RAM there is no benefit. In other words, even if you add 8 GB or 16 GB, you will get 4 GB performance. And Vista supports 64-bit 8GB, Windows 7 Ultimate 64-bit 192GB, Windows 10 64-bit Home 128GB, and Enterprise, Education and Pro 2TB. But the question is do you really need so much radam?

Many times when we buy a device or change the RAM we keep in mind how many softwares or games we upgrade or buy. We think 4GB or 8GB is enough for this software or these games, 2GB RAM is enough for smartphones. Yes, RAM is enough to run that software or games, but besides running that software or games, RAM has more work to do.

You also need RAM to perform various tasks on your computer and smartphone operating system. Even if you have a built-in AGP on your motherboard, it shares V-RAM from the original RAM. Or buy 2/4 GB more RAM than the amount of RAM required for games. If you do not, your device will be slow.

Size and frequency of RAM

Most of us computer or smartphone users know how much RAM we have in our computer or smartphone, but when one of our friends or relatives tells us who has so much GB RAM in my phone or so much GB RAM in my computer it means more than us; Then we don’t think that his system is faster than our system. Yeah Al that sounds pretty crap to me, Looks like BT aint for me either.

There are many different things to check the performance of RAM. One of the ram speed or frequency. The performance of two RAMs of different frequencies or speeds of the same storage can have very good-bad differences. Similarly, a computer user using 8 GB RAM and 16 GB RAM will not find any difference. You can find the difference only in high end work such as gaming, video editing and rendering, 3D modeling, virtualization , professional sound and image editing, deep learning.

If you are a computer user with 8 GB RAM; However, I do not think it is necessary to upgrade from 8 GB to 16 GB unless absolutely necessary. If you want better performance on your same computer, buy a good frequency version of 8 GB RAM, which will support your mainboard. Basically you can do this if you are a normal computer user, but if you are a high end computer user, you need to increase the RAM according to your needs.

One slot, one size and frequency of RAM

Advertisements

We know that our normal work computer usually has three or four slots for RAM and many of us have a misconception that those slots should only have RAM of the same size. For example, if 8 GB is installed in one slot, then 8 GB should be installed in another slot. In fact, it is wide, but it is not, you can put different sizes of RAM in different slots.

However, regardless of the size, it is better to install RAM with different frequency, because if RAM is installed at different frequencies, good performance is not available, and if your mainboard or machine is 1333 or 1600 frequency and you install RAM at 2133 frequency, then your device will work up to 1333. So nothing will come of it except a waste of your money. However, if RAM of the same brand, same capacity, same frequency is installed in different slots, you will get better work consistency and for this reason, if you install RAM of different size, different frequency, you will get much better performance than you get. But yes if you have 4GB in one slot you can put 8GB in another slot, no problem, here you set dual channel mode, you will get a smooth performance.

Using Radam Booster:

There are many of us who claim to be smart and computer and smartphone experts and they are smart enough and they have a pretty good idea about technology but I do not understand why they use RAM booster or memory optimizer type software, in fact it is about our RAM. A misconception. And as a result of this misconception, we started using software called RAM Booster or Memory Optimizer and hit the ax on our own feet.

Suppose you are doing different things on your device, now your RAM will be full. This is the general rule. When you finish your work again, you will see that your RAM is much more empty than before, that is, your RAM is working properly. Radam was not created to be empty. Your operating system and software are designed in such a way that it can occupy RAM space.

So why go against your system and use cleaner software? Even these cleaner booster software slows down your device as you delete some important data processing of the system. Surely you understand? Unlike a RAM hard drive, it has an auto-adjust system. If RAM is 4 GB, it can be used for Writing, Erasing, Rewriting while using 4 GB space. So in my opinion it is better not to use RAM booster or cleaner apps or software.

On the way:

I hope your misconceptions about RAM are gone now, now you realize how much RAM you need, if you still have any questions about RAM, please comment and I will try to answer your question as soon as possible. , And yes, one more thing, if you like it, don’t forget to share the post, stay well till today.
