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

If you’re a mobile device user, you’ve probably heard the names of phone parts like the processor or video card, etc. And RAM is no exception. So what is RAM, what does it mean on a mobile device? Let’s learn about RAM with Tnhelearning.edu.vn!

 What is RAM?

RAM stands for Random Access Memory – one of the most important factors besides the processor. RAM is the machine’s temporary memory that helps store current information so that the CPU can access and process it.

RAM cannot store data when the power supply is lost. If the device loses power, turns off the device, the data on RAM will be erased.

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 this time the CPU will access and retrieve data from RAM to display it in response. user action again.

What is the difference between phone RAM and laptop RAM?

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

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

Second, the RAM on the phone is attached directly to the processor chip. Therefore, you cannot easily upgrade or replace it like on desktops and laptops.

Finally, the phone RAM will be shared by both the processor and the graphics processor without the RAM dedicated to graphics processing.

What does RAM mean on mobile devices?

In general, RAM memory is an intermediary device between system files including ROM and processor with the task of providing information, tasks and command lines as quickly as possible.

The information the processor needs will be stored in RAM waiting to be accessed, be it operating system files, application data, game graphics, routine tasks or anything. should be retrieved immediately.

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

The larger the RAM, the smoother the phone is, smooth?

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

The larger the amount of RAM, the faster the memory cycle… 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 that cause memory overflow.

However, having a large amount of RAM cannot confirm that the device is smooth or not, but it depends 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 has only 1 GB RAM, but the processing efficiency is higher than Android models with 2 GB or 3 GB RAM.

 How much RAM is enough?

This is the question that many people will ask when talking about RAM. In fact, more or less RAM depends on the user’s needs.

For needs that only need to meet common tasks such as surfing the web, watching movies or even playing some light games, 2 GB to 3 GB RAM is more than enough.

As for a group of customers with higher requirements such as manipulating heavy applications or playing games with medium graphics or higher, at least 4 GB RAM or more will be more reasonable.
