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

If you're a mobile device user you've probably heard the names of the parts of your phone like the processor or the video card, ... and RAM you've probably heard too. So you already know what RAM is? And what does it mean on a mobile device? So let's learn about RAM with WebTech360!

1  What is RAM?

RAM is short for Random Access Memory - one of the most important factors besides the processor. RAM is the temporary memory of the machine to help store current information so that the CPU can access and process it.

RAM cannot store data without the power supply. If the device loses power, turns off the device, the data in RAM will be deleted.

2 Mechanism of  action of RAM

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 the RAM to display the response. user action again.

3 How is phone RAM different from laptop RAM? 

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

First, phone RAM is designed with small size and low power consumption to suit 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.

What does 4 RAM mean on a mobile device?

In general, RAM is the intermediate device between the system files including the ROM and the processor, and is tasked with delivering information, tasks, and commands as quickly as possible.

The information that the processor needs will be stored in RAM to wait for access, be it operating system files, application data, game graphics, common tasks or anything. should be retrieved immediately.

Each RAM cell has an address. Without RAM, a smartphone cannot even perform basic tasks because accessing data files is extremely slow. So RAM is very important for a mobile device.

5 larger RAM the smoother and smoother phone

The memory of RAM is much lower than the memory of the hard drive, but RAM is the place for the CPU to get data to process so the write and read speed in RAM is very fast. RAM plays a crucial role in the computer's ability to multitask. 

The larger the RAM capacity, the faster the memory cycles… the more comfortable the device can run at the same time. If the amount of RAM is not enough, the device will experience lag or hang due to a large number of tasks causing memory overflow.

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?

This is the question that many people will be wondering when talking about RAM. In fact, more or less RAM depends on the needs of the user.

For the needs of just meeting common tasks like surfing the web, watching movies or even playing some light games, 1 GB to 2 GB RAM is more than enough.

As for customers with higher requirements such as manipulating heavy applications or playing games with average graphics or higher, RAM of at least 2 GB or more will be reasonable.
