Random Access Memory: What is it and What does it do in Computer?


Have you ever wondered what all those strange numbers and letters mean on your computer’s system information? That gibberish is your computer’s Random Access Memory or RAM for short.

RAM is a very important part of your computer- without it, your computer would be unable to function. In this post, we’ll discuss what RAM is, what it does, and how to check your RAM’s health.

What is RAM?

RAM, or Random Access Memory, is a type of computer memory.

RAM is where your computer stores the active data that is currently being used. This includes the programs you're using, the documents you're working on, and any active website tabs you have open. Basically, anything that's currently on your screen is stored in RAM.

When your computer is turned off, RAM loses its data. That's why if you turn your computer back on and try to pick up where you left off, you'll usually be prompted to re-open all of the programs and documents you had open last time.

RAM can be measured in megabytes (MB) or gigabytes (GB). A gigabyte is 1,000 megabytes. Most computers come with anywhere from 2-8GB of RAM.

How does RAM work?

RAM is short for Random Access Memory. It's a type of computer memory that stores data and information that you're actively using.

Think of RAM as your computer's short-term memory. When you're working on a document, for example, the data is temporarily stored in RAM. This allows your computer to access the information quickly, which helps with performance.

When you close a program or save your work, the information is transferred from RAM to your computer's long-term storage (usually your hard drive). This frees up space in RAM so that you can continue working without any lag time.

What are the different types of RAM?

RAM can be classified into two different categories: static and dynamic. Static RAM, or SRAM, is a type of memory that holds its contents as long as power is supplied to it. Dynamic RAM, or DRAM, is a type of memory that requires a constant flow of power in order to hold its data.

There are also different types of DRAM: SDRAM, DDR SDRAM, DDR2 SDRAM, DDR3 SDRAM, and DDR4 SDRAM. They all have different speeds and capacities, so it's important to do your research before purchasing a new computer or upgrading your old one.

How much RAM do I need?

When it comes to RAM, you don't want to shortchange yourself. The more, the merrier!

But seriously, the amount of RAM you need depends on what you plan to use your computer for. If you're a casual user who just wants to surf the web, check email, and maybe do some light word processing, then 2-4GB of RAM should be plenty.

If you're a power user who likes to dabble in photo and video editing, gaming, or intensive programming, then you'll want to go for 8GB or more. Keep in mind that these are just general guidelines - if you have any specific questions about how much RAM you need, consult your computer's specs or manufacturer.

What are the benefits of upgrading RAM?

When it comes to your computer, RAM is one of the most important components.

RAM stands for Random Access Memory and it's what your computer uses to store data. This means that anything from the operating system and programs you're using to the websites you have open and the files you're working on will be stored in your RAM.

The great thing about RAM is that it's easy to upgrade. This means that if you find that your computer is starting to slow down, you can easily upgrade your RAM and give it a new lease of life.

When you're looking to upgrade your RAM, it's important to make sure that you get the right type for your computer. Check your computer's manual or contact the manufacturer for more information.

How to install RAM

Installing RAM is a fairly simple process, and can usually be done in a few minutes.

The first step is to find the RAM slots on your motherboard. They're usually located near the CPU, and will be clearly marked. Match the RAM modules you bought to the slots on your motherboard, ensuring that the notches on the module match the bumps on the slot.

Once they're in place, use your hands to gently push down on each module until it's fully seated. Do not use excessive force, as this could damage your hardware.

Once they're in place, attach the power cables to the modules (usually labeled CPU_PWR and MEM_PWR) and plug them into an available power socket. Your computer should now be ready to use!


RAM is a critical component of any computer and is responsible for running programs and allowing data to be accessed quickly. When shopping for a new computer, it’s important to understand the different specifications and what they mean in order to make an informed purchase. By understanding RAM, you can be sure that your computer can handle the tasks you need it to.
