What is RAM, what does it mean in electronic devices, mobile devices?

What is RAM? You already know the main function of mobile RAM and what role does it play? In this article I will learn with you.

1. What is RAM?

RAM, which stands for Random Access Memory, is one of the components found in most electronic devices today.

RAM is able to read and write itself, but data is lost when the power supply is lost on the phone or tablet (power off).

2. How RAM works

When we open an application on a smartphone or on a tablet , the software's data will be transferred from the hard drive and stored in RAM, at which point the CPU will access and retrieve the data from RAM to display the response. re-manipulate the user.

3. Phone RAM is different from laptop RAM

Basically, they all have the same function, but due to the nature of the device, these 2 types of RAM will have some differences.

Firstly, phone RAM is designed with small size and low power consumption to match the mobile nature and use of battery on smartphones.

Second, the phone's RAM is directly attached to the processor chip. Therefore, you cannot easily upgrade or replace like on desktop computers and laptops.

Finally, the phone's RAM is shared by both the processor and the graphics processor, with no dedicated RAM for graphics processing.

4. What RAM Means on Mobile Devices

Along with the processor and the graphics chipset, RAM makes a lot of sense on a mobile device. The processor information needs to be stored in RAM, waiting to be accessed.

These could be operating system files, application data, game graphics, or anything that needs to be accessed quickly during operations. Without RAM, the device will not be able to perform even the smallest task.

5. The more RAM the phone gets, the smoother and smoother the phone gets

Currently, the processor has achieved extremely impressive levels of performance, so a weak phone or tablet also depends quite a lot on the amount of RAM attached.

In other words, the faster the processing speed, the more applications you will run at the same time, requires large amount of RAM to load all these applications.

The more RAM a phone or tablet has, the more information it can store, allowing more apps to run in the background.

3D gaming is better because games, especially 3D graphics games, can use a lot of RAM to store graphics, 3D shapes and sound, and do not slow down or experience lag.

However, having a large amount of RAM cannot confirm whether the device is smooth or not without having to rely on many factors such as a well-optimized operating system, the amount of RAM does not need to be too large.

For example, the iPhone 6 RAM is only 1 GB, but the processing efficiency is higher than the Android models with 2 GB or 3 GB RAM.

6. How much RAM is enough?

For those who use smartphones with basic elements such as surfing the web, listening to music, ... RAM 1 to 2 GB is completely able to meet.

And with higher demand, processing power applications, high graphics gaming , you should choose to buy devices at least larger than 2 GB to be able to operate stably, avoiding unwanted agents.
