Question

What is ram (in computer desktop)? why do we need ram?

so, If I have to analysis Ram 36 GB (8GB x4) DDR4/ 3000 MHZ.

what is 36 GB of ram? what is DDR4? and what is 3000 MHZ?

Answer 1

RAM:

Random access memory, or RAM, is one of the most important components of not only desktop PCs, but laptops, tablets, smartphones, and gaming consoles. Without it, 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.

Why do we need RAM:

RAM is essentially the core of your computer. It can be considered just as important as your processor, or hard drive. With the right amount of RAM on your computer the performance of your PC and the ability to support various types of software is optimized.

The overall performance of your computer is determined by how well your CPU and RAM work together. The more RAM your CPU has access to, the easier its job becomes, which enables a faster computer. If you do not have a sufficient amount of RAM than your CPU has to work much, much harder to transfer data, which severally damages the computer’s performance.

Random access memory also helps your system support software. Every piece of software requires a minimum amount of space and memory to be able to run smoothly. If your computer does not have enough RAM to support all the software systems you are running, or trying to run, they move so slow that it might not be worth running that software system. Additionally, if there is not enough storage room, the software might not run at all.

RAM is such a key element to how your computer functions that if one storage location out of a million is damaged your entire system can potentially crash.

These few reasons should have helped convince you why during your next laptop, or desktop purchase you should seriously consider how much RAM is available. Doing so would be more beneficial to you and your wallet. Comparing RAM capacity instead of key board light options and deciding which OS you want based on its animal icon, seems like the more educated decision.

Given that 36GB RAM means the memory size of that particular system is 36 GB only.

DDR4 means it is the one type of RAM which will operate between the frequency of 2133-3000MHZ.

3000MHZ it is the frequency of that clock supports the 36GB RAM .
