uses of ram

RAM is used to store data temporarily while the computer is running. This data includes operating system files, applications, and files that are currently in use. When you open an application or program, it is loaded into RAM for quick access and processing. The more RAM your computer has, the more applications and programs you can have open and running simultaneously. Furthermore, RAM is vital for multitasking and ensuring that each program runs efficiently without lag or delay.

Virtual Memory

RAM also plays a role in virtual a computer’s ability to use a section of the hard drive as additional memory. When RAM is full, and the computer needs to store more data, it will use virtual memory. However, using virtual memory can slow down the computer’s performance as the hard drive is much slower than RAM. Virtual memory is an essential feature for systems with limited physical RAM, but it’s not a substitute for adequate RAM capacity.


For gamers, having enough RAM is crucial. When playing a game, the computer loads files and information from the game into RAM for quick access. The more RAM the computer has, the faster the game can run, and the better the overall gaming experience will be. Additionally, modern games often feature complex graphics and large open worlds that require substantial RAM to prevent stuttering and lag during gameplay.

Video Editing

Video editing is another task that can benefit greatly from having enough RAM. When editing a video, the computer needs to process large files and data quickly. Having enough RAM allows the computer to handle the data without slowing down or crashing. Video editing software also utilizes RAM to preview edits in real-time, making an ample amount of RAM essential for a smooth editing workflow.

RAM Facts

Now that we understand the uses of RAM let’s dive into some interesting facts about this crucial component. RAM has evolved over the years, and understanding these developments can help users make better choices about their hardware upgrades.

Volatile Memory

RAM is considered volatile memory, which means it requires power to maintain the stored data. When the computer is turned off, the data in RAM is lost, and the computer will need to reload the data from the hard drive when it’s turned back on. This characteristic is why computers take time to start up and load programs after being powered on.


RAM is much faster than a hard drive or solid-state drive. This is because RAM is directly connected to the computer’s processor, allowing for quick data access and processing. This speed is crucial for tasks that require quick data retrieval, such as gaming or video editing. The speed of RAM is typically measured in MHz, with higher numbers indicating faster performance.

Size Matters

The size of a RAM module is not indicative of its speed or performance. A smaller module with the same specifications as a larger one will have the same performance. However, having more RAM modules will allow for more data to be stored, and therefore, more applications and programs to be open and running simultaneously. The total amount of RAM your system can utilize is often more important than the size of individual modules.

Types of RAM

There are various types of RAM available, and each one has its own unique characteristics. Let’s take a closer look at the most common types of RAM used in modern computers. As technology advances, newer types of RAM emerge with improved performance and energy efficiency.

Dynamic Random Access Memory (DRAM)

DRAM is the most common type of RAM and is used in most personal computers. It is a type of volatile memory that stores data in capacitors. DRAM is relatively inexpensive and has a high data transfer rate, making it ideal for everyday use. DRAM requires regular refreshing of data to maintain its integrity, which is managed by the memory controller.

Static Random Access Memory (SRAM)

SRAM is another type of volatile memory but is faster and more expensive than DRAM. It is often used in cache memory, which is a type of high-speed memory used to store frequently used data for quick access. SRAM is also used in specialized applications, such as routers and switches, due to its high performance. Unlike DRAM, SRAM does not need to be refreshed, which contributes to its speed advantage.

Double Data Rate (DDR) SDRAM

DDR SDRAM is a type of DRAM that can transfer data twice per clock cycle, making it twice as fast as regular DRAM. It is currently the most popular type of RAM used in personal computers and is available in various versions, including DDR2, DDR3, and DDR4, with DDR4 being the most recent and fastest standard. Each iteration of DDR SDRAM has improved on the previous generation in terms of speed, power efficiency, and maximum capacity.

Non-Volatile Dual In-line Memory Module (NVDIMM)

NVDIMM is a type of RAM that can retain data even when the computer is turned off, making it non-volatile. It is a hybrid of DRAM and solid-state drive (SSD) technology, providing the speed of DRAM and the storage capacity of an SSD. This type of RAM is often used in enterprise servers and data centers where data persistence and speed are critical. NVDIMMs are particularly useful for applications that require fast write speeds and data integrity in the event of power loss.

How Much RAM Do You Need?

Now that we understand the different types of RAM let’s explore how much RAM is required for various tasks. The right amount of RAM for you will depend on your specific use case and the demands of the software you use.

Basic Use

For basic computer use, such as browsing the internet, checking emails, and using word processing software, 4GB of RAM is sufficient. This amount of RAM will allow for multiple applications to be open and running simultaneously without any noticeable slowdown. However, as operating systems and applications continue to develop, 8GB is becoming the recommended minimum for new computers to ensure future-proofing and smoother performance.


For gaming, 8GB of RAM is recommended, but 16GB is becoming the standard for most modern games. Having more RAM will allow for a smoother gaming experience and will prevent any potential slowdowns or crashes. Some high-end games and gaming enthusiasts may even opt for 32GB of RAM to ensure the best possible performance, especially when running other applications in the background.

Video Editing

Video editing requires large amounts of RAM to process and store large video files. 16GB of RAM is recommended for most video editing tasks, but 32GB or more may be necessary for more complex projects. Professional video editors working with 4K or 8K footage or complex effects may benefit from 64GB of RAM or more to ensure seamless playback and rendering.

Virtual Machines

If you plan on running virtual machines on your computer, you will need more RAM. Each virtual machine requires its own amount of RAM, so be sure to have enough to support the number of virtual machines you plan on running simultaneously. For a comfortable experience with multiple virtual machines, 32GB of RAM or more is advisable, depending on the resource requirements of each virtual environment.
