You may be a normal user, just sitting and wondering what this RAM (random access memory) for instance you are buying a laptop, building PC or even getting a new smartphone, Not sure What is RAM (Random Access Memory ) exactly ?
we are going to explain each and every thing about it: What is RAM (Random Access Memory ) or how it works? Find out below why RAM is necessary to run your device like a computer smartphone or laptop and what it does.
What is RAM (Random Access Memory ) ?
RAM is short for “random access memory” . Alternatively referred to as main memory, primary memory, or system memory,
It is one of the most fundamental elements of computing. It is the super-fast and temporary data storage space that a computer actively uses to store so that it can be accessed quickly whenever needed.
The more programs your system is running, the more memory you’ll need. Since it is temporary storing the data it goes away when the power turns off.
Types of RAM
By the late 1990s and early 2000s, users had their choice of static RAM (SRAM), Dynamic RAM (DRAM), or Synchronous Dynamic RAM (SDRAM)
Nowadays, the most common type is DDR-RAM, and there are various iterations, including DDR2, DDR3, DDR4, and DDR5. DDR stands for double-data rate and allows multiple file transfers at the same time. Current speeds are about 25 gigabytes per second for the latest DDR4-RAM.
There are also multiple types of speeds of DDR4 memory. By default, these memory sticks run at around 2500 MHz. for maximum performance out of your memory, you can get higher clocked RAM
VRAM (Video Random Access Memory) is also a type of ram which on your graphics card and is used for loading graphical data (such as games).
Video RAM is even faster than normal memory and comes in the form of GDDR5X or HBM memory with higher bandwidths.
What does RAM do, exactly?
RAM is temporary storage that goes away when the power turns off. It’s very fast, which makes it ideal for things the computer is actively working on.
Such as applications that are currently running (for example, the web browser in which you’re reading this article) and the data those applications work on or with (such as this article).
RAM is not hard to understand can help to think about RAM with the analogy of a physical desktop.
It allows you to work on a variety of projects, and the larger your desk, the more papers, folders, and tasks you can have out at one time.
You can quickly and easily access the information without going to a filing cabinet (your storage drive).
When you’re finished with a project, or leaving for the day, you can put some or all the projects in the filing cabinet for safekeeping.
Your storage drive (hard drive or solid state drive) is the filing cabinet that works with your desk to track your projects.
That’s simple right ?
Your windows tries to heal itself
Your PC optimizes itself. One notable example is the operating system’s own process.
For example, if you use Windows, its key functions — such as the ability to display images on your screen — are copied into RAM, because the OS needs super-fast gain to the devices you use all the time.
Not every device driver is loaded into RAM immediately, but many of them are.
Another example is a Windows feature called SuperFetch, which records your usage patterns.
Based on your existing behavior, it automatically pre-loads applications and files into RAM when you turn on your PC. This makes working with your computer significantly faster.
Currently, the largest single stick of RAM is 128 GB.

How much memory do I need ?
Well that’s completely your choice and for what purpose you are going to use the device How much RAM do you need? It depends on the kind of work you do, how many things you do at once, and how impatient you are.
As with so many other parts of computing, we always want our devices to respond instantly!
With today’s standards we would recommend you have more than 4GB , best in budget is 8GB it can be compatible for at least next 2years to come
Today, a web browser with 10-20 open tabs can easily consume over 2200 MB — or 2.2 GB — of RAM add some background process and other application consumption approx 4 gb covered
Here are our recommendations, which apply to any operating system or personal computer hardware:
4 GB of RAM:
If you’re only browsing the web, working with basic Office applications and maybe dabbling a bit in personal photo editing, you’ll be fine with 4 GB of memory.
- 8 GB of RAM: Heavy multitaskers or light gamers should choose a computer with 8 GB of RAM.
- 16+ GB of RAM: Some tasks are inherently computing intensive, such as serious gaming, video editing, and programming. “Enthusiast” users who never want to experience slowdowns will need 16+ GB of RAM to be happy.
What should I look out for when buying RAM? (for the geeks)
Most important thing to keep in consideration is the budget you want to spend on it.
As mentioned above, today’s DDR4 RAM clocks in at around 2133 and 3000 MHz.
Gamers or other hardcore computer users (multimedia editors) should look at higher clocked memory with specifications of up to 4800 MHz.
Such memory comes from manufacturers like G.Skill or Corsair.
However, while clock speeds are one thing, the other factor you should consider is latency,
latency is the time delay between when a command in memory is entered and when it’s executed.
The lower this number, the higher the performance, as you get fewer delays between instructions.
To get the best performance, find memory north of 4000 MHz with a latency of around CAS (Column Address Strobe) 15-18.
(For regular users, this is unlikely to be an issue you can ignore , but for gamers it can be helpful.
32-Bit Windows versions users note this
you need to keep in mind that you can’t just install infinite amounts of RAM in your PC and expect it to work.
To use more than 4 GB of memory, you need to run a 64-Bit version of Windows 32-bit versions are limited to address 3.5 GB of memory only.
Many Windows 7 users are still on 32-bit editions,
so if you want to use 4 GB of RAM or more, you will definitely need to jump on the 64-bit version.
But, beware of installing a 64-bit version on a very old machine with less memory since that might have a counteracting effect.
If your system is slow or unresponsive, that’s the sign your computer might need more memory.
A memory upgrade is one of the easiest and most cost-effective ways to improve performance.
thats it guy , i know it was quite long , so much information to cramp in some paragraph isn’t possible right?
