RAM কিভাবে কাজ করে?


মেমরি কম্পিউটারের একটি গুরুত্বপূর্ণ অংশ যা তথ্য সংরক্ষণ করে এবং পুনরুদ্ধার করে. র্যান্ডম অ্যাক্সেস মেমরি (র্যাম) কম্পিউটারে ব্যবহৃত প্রধান ধরনের মেমরি. It is also called as volatile memory because it loses its data when the power to the computer is switched off.

RAM has two main typesdynamic RAM and static RAM. Dynamic RAM uses a small amount of electricity to store data, whereas static RAM uses more electricity but stores data for longer periods of time.

RAM is also known as dynamic random access memory (DRAM). This type of memory can be used for temporary storage for instructions and data.

The most common DRAMs are DDR3, DDR4, and LPDDR3.

Random Access Memory is an important component of computer systems. It is a fast-access data storage device that can be used as a temporary holding area for data.

RAM is typically used as a short-term memory for computers by storing the most recently accessed information in RAM. This makes it easier to process multiple tasks at once and allows the machine to run faster.

What is Random Access Memory (র্যাম)?

Random Access Memory is a type of computer memory that allows data to be accessed in any order. It is the most commonly used type of memory because it can hold large amounts of data in small spaces.

RAM has been used for decades and it’s still one of the most important components in a computer. It’s also found in many other devices like smartphones, tablets, ল্যাপটপ, and digital cameras.

RAM is also used as a temporary storage for applications and operating systems. The more RAM you have, the faster your computer will run.

Random access memory is a system is based on the principle of random access and it has a higher speed than other types of memory.

RAM is used for temporary data storage, so it is faster than hard drives or SSDs. It also has lower power consumption and better performance compared to other types of memory.

How is RAM Key to Your Computer’s Performance?

RAM is an important part of your computer. It does not have a storage capacity, but it does have a speed.

RAM is used by all types of devices including mobile phones, tablets and computers. The more RAM you have, the faster your device will be able to perform tasks that require a lot of processing power.

RAM is a data storage device which is used to store data temporarily. It is also known as theworking memory” একটি কম্পিউটারের.

RAM was originally used to store only one program at a time, but now it can be used to store multiple programs and processes simultaneously.

RAM allows the computer to access information faster than other types of storage devices such as hard drives and flash drives.

RAM acts as a temporary memory for the CPU, where it stores the data it needs to run its operations.

RAM is crucial to the performance of your computer because it enables your system to run as quickly as possible with the least amount of power consumption.

This memory is so important that it cannot be replaced by any kind of technologynot even SSDs. You can expand this RAM capacity in order to enhance your performance.

আজকাল, the performance of RAM has reached a point where it is better than other types of storage devices. সেখানে 3 main types of RAM: volatile (DRAM), non-volatile (NVRAM) and persistent memory (SRAM).

Types of RAM in Computers and its Uses

RAM is a type of computer memory that stores and retrieves data quickly by using random access. RAM has been evolving since its first introduction in 1966.

RAM uses can be broadly grouped into two categoriesa computer processor needs to know where the data is physically stored and a computer needs to have enough physical memory to store it.

The former is known as volatile RAM and the latter is known as non-volatile RAM. সাধারণভাবে, the use cases of the latter are more important in today’s era of smart devices where cloud services are used extensively.

RAM devices are used in different ways to help in the performance of a computer. Different types of RAM devices have different purposes.

Types of RAM:

SRAM: Static Random Access Memory.

DRAM: Dynamic Random Access Memory.

RDRAM: Reusable Dynamic Random Access Memory.

RAM is the most popular type of memory in PCs today. There are different types of RAM memory system, including DDR, RDRAM and SDRAM.

The very first RAM was on a mainframe computer which was used to store instructions and data in advance but it did not exist yet on personal computers.

    র্যান্ডম অ্যাক্সেস মেমরি, or RAM (pronounced as ramm), is the physical hardware inside a computer that temporarily stores data, serving as the computer’s “কাজ” গুরুত্বপূর্ণ কিছু করার সময় আপনি যদি মাল্টিটাস্কিং করেন.

    Additional RAM allows a computer to work with more information at the same time, which usually has a dramatic effect on total system performance.

    Random access memory, or RAM, is one of the most important components of not only desktop PCs, but laptops, tablets, smartphones, and gaming consoles. এটা ছাড়া, doing just about anything on any system would be much, much slower. Even not having enough for the application or game you’re trying to run can bring things to a crawl, or make it so they can’t even run at all.

    সংক্ষেপে, it’s an extremely fast type of computer memory which temporarily stores all of the information your PC needs right now and in the near future. It’s where your computer loads up all of the things it thinks it’ll need to find out soon, so that when it does, it can read it super fast. It’s quite different from your system’s storage, like its hard drive, where information is stored long term.


    Perhaps the best analogy for what RAM is, is to think of it as like your system’s short-term memory. It’s quick at learning new things and can load in all of the information about your web browser, the image editing tool you’re using, or the game you’re playing so that you can access it quickly. You don’t want to have to dig through your slower storage, like a hard drive or even a solid state drive (SSD) every time you want to open a new tab, or load a new enemy to shoot. As fast as they are compared to storage of years gone by, they’re still far slower than RAM.

    Data that’s in the short term memory, or RAM, can be read from anywhere at almost the same speed and because it has a hard-wired connection to your system, there’s no real latency in cabling or connection.

    Like short-term memory, যদিও, RAM is not designed to stay focused forever and is ready to move on to the next task at a moment’s notice. It’s what is described in computing as “volatile,” that is, once it loses power, it forgets everything it’s learned. The makes it perfect for handling the multitude of high-speed tasks that your system throws at it on a daily basis, but it’s also why we need storage systems like hard drives and SSDs, to actually hold our information when you turn your system off.


    RAM is a bit of a catch-all term, like “memory,” and actually covers a few different types. Most of the time when people are discussing RAM or memory, what they’re actually talking about is technically DRAM (dynamic random access memory), or more accurately for modern systems, SDRAM (synchronous dynamic random access memory). The terminology doesn’t really matter beyond technicalities, but it’s useful to know that the terms are relatively interchangeable colloquially.

    The most common types of RAM that are sold today is DDR4, though older systems may use DDR2 or DDR3. Those simply denote the generation of RAM used in that particular system, with each successive one offering faster speeds through greater bandwidth — a higher megahertz (MHz) rating. Each generation also saw physical changes, so are not interchangeable.

    Another common term, especially in the video game space is VRAM, or video RAM. Although once a technology in its own right, VRAM is today used (technically erroneously) to denote the memory available to a graphics chip or built on to a graphics card. That’s actually called Graphics DDR SDRAM, or more commonly GDDR. Most modern graphics cards will use GDDR5, though some use a newer GDDR5X standard and upcoming generations may even come with GDDR6 memory.

    Some niche graphics cards utilize a unique form of RAM called High-Bandwidth-Memory (HBM and HBM2) which has some unique performance advantages, though it is typically expensive and supply issues have meant it hasn’t seen widespread adoption.


    The biggest consideration when buying RAM is the size of it. You need a minimum amount of RAM to run a desktop or laptop operating system and many games and applications have a minimum amount too. Those requirements are listed in the gigabytes, or GB and are often between 1GB and 8GB, depending on how demanding the application is. Having more than the minimum is important, as you’re unlikely to just be running one application at a time, but having massive amounts doesn’t necessarily make your system faster.

    It’s also not the only aspect of RAM that’s important. While more gigabytes of RAM can help with multitasking, you can see more improvement in the speed of your system, certain games and applications through using faster memory. স্মৃতি, like CPUs, has its own clock speed, which effectively controls how much data it can handle per second when combined with a few other factors. The total speed of the memory is discussed as bandwidth, in megabytes per second, but traditionally memory is marketed with a MHz speed.

    Typical DDR4 memory runs around 2,133MHz, but there are some that can run upwards of 4,000MHz for the fastest kits available. You would see these marketed as DDR4-2133, and sometimes with the confusing PC label applied too. The number that follows that is simply an eight times multiplication of the MHz speed. You might see it listed as DDR4-2133 PC4-17000, উদাহরণ স্বরূপ.

    Timings are another aspect of memory that can have an impact on RAM performance, though they aren’t as important as they used to be. It’s effectively the time between clock cycles, and as memory speed has increased, timings, or the latency of the memory have increased (gotten slower) খুব. Typically it’s listed as several numbers separated by dashes, যেমন 15-15-15-35, or similar. When it comes to buying memory, timings are only really important if you’re considering high-performance memory for benchmarking or top-tier gaming and aren’t of real concern to the average consumer.

    পোর্ট স্ক্যানিং, it’s important to know about channels. Most memory sold today is at least dual-channel, and it allows two sticks of RAM of the same type and speed to operate faster by providing better access to the CPU’s memory controller. যাহোক, high-end RAM kits sold with three or four modules may support triple or even quad-channel memory.

    In practical purposes, it doesn’t make a huge difference to everyday performance, but if you want to take advantage of dual or more channel memory, you just need to make sure to install it all in the right colored slots on your motherboard.


    RAM is very important in that your desktop needs it to run and tablets or smartphones without much of it tend to run very slowly indeed. যাহোক, will having tonnes of it or the highest MHz rating mean your system is super fast? Not necessarily.

    Having enough RAM matters and having RAM that isn’t bargain basement slow is a good idea, especially if you plan on doing complicated image or video editing tasks, or playing games that tend to be CPU limited. যাহোক, when it comes to improving your system’s overall performance, it’s important to weigh up the costs involved. A faster CPU or graphics card is almost always going to have a bigger impact on your systems’ overall speed than faster memory.

    Upgrading from a hard drive to an SSD is also a big step if you haven’t taken it yet, as that speeds up by far the slowest storage on your system by a huge margin and contributes massively to making it feel more snappy.

    As with any computing device, you are usually limited the most by your slowest component, so slow memory can hold you back if it’s the worst part of your configuration. Unless you’re doing anything particularly intensive though, just make sure you have a little more than what you need and that it’s not the worst available, then you’ll probably be fine. If you want something more powerful there are a wide array of configurations of speed, size and latency for you to choose from. Some even have RGB LED lighting too.
