What is RAM? – Definition, Types, and More

Random-access memory, or RAM as it is better known, is key to the performance of any PC, tablet, phone, or even game console.

In almost all our reviews of smartphones, tablets, and laptops, you will see that we mention RAM’s amount that each device has.

It is an easy way for manufacturers to differentiate between the different configurations of the same product, considering how fundamental it is for any computer’s performance.

Simply put, RAM is a component that provides your device’s short-term memory. Temporarily store the data you need for current or impending tasks before erasing it once it is no longer needed.

IT includes everything you need to keep your operating system running. As well as open applications such as web browsers, editing software, and games.

It’s also the main reason you can get back to doing these tasks with almost no interruption. RAM’s great advantage over an SSD or other type of flash storage is that it can be recovered almost instantly.

All data stored in RAM is erased when you finish that task. That’s the point where you can save it to ROM for future use. IT is the main reason you need much less RAM, as it is almost impossible to carry hundreds of GB operations at once.

These are the best smartphones of 2021.

How much RAM do I need?

It brings us to the next big question: how much RAM do I need? There is no single answer for all cases since it will depend on the device you use and the use you want to give it.

The most complex tasks tend to continue to be performed on a PC, so that is where the most outstanding amount of RAM is usually found. IT can exceed 1TB, but it is an exaggeration for the vast majority of people, as we have said before.

The PCs for gaming and high-end laptops usually come with 16 GB. But 8 GB should be acceptable for everyday use. The significant advantage of desktop computers is that the RAM can often be upgraded manually to use improved technology or add additional GB.

8 GB is a standard on Android phones, although 6 GB or 4 GB can be dispensed for basic tasks. Flagships like the Samsung Galaxy S21 Ultra come with up to 16GB. Which is also what you’ll find on next-gen consoles like the PS5 and Xbox Series X.

However, it’s also true that iPhones typically need less RAM than their Android counterparts. And even the top-end 12 Pro Max only offers 6GB.

One of the main reasons is the integration that Apple has between the hardware and software and using a more efficient programming language that would not be possible for Android and is many phone manufacturers.

What are the two types of RAM?

There are currently two main types of RAM: dynamic (DRAM) and static (SRAM). DRAM is the standard found in most modern computers and comprises a transistor and a capacitor in an integrated circuit.

To retain the data, it needs to receive a new electrical charge every few milliseconds. IT can be achieved from a direct power supply in desktop computers and game consoles or the internal battery in laptops and mobile devices.

There are three types of RAM, but the most popular in modern technology is Double Data Rate Now. Its fourth-generation (DDR4) doubles the bandwidth of everyday DRAM without increasing the clock speed

SRAM is typically faster but is often expensive and requires a constant power source to keep memory data. In devices designed to be portable, it is clear that this type of RAM is not suitable.

If you’ve just upgraded your desktop’s RAM, here’s how to optimize it for maximum performance.
