Random Access Memory in Computers: A Complete Guide

Robert Heath Dennard merits his place in computer history more than anybody else. He imagined a world with smaller, random-access memory at a period when data was stored on punchcards. But do you realize how crucial his innovation, RAM, is to run a computer?

RAM is your computer’s short-term memory, which aids in the smooth operation of programs. Continue reading to learn how to upgrade your computer’s RAM.

What is RAM in a computer?

Random-access memory (RAM) is a type of memory that can be accessed at any time. It’s a type of temporary memory employed by computers similar to the human body’s short-term memory. Unlike HDD or SSD, where files are preserved in permanent copies, it is constantly overwritten and refreshed.

There are several advantages to this. It’s lightning-fast, allowing your computer to do and recall fundamental tasks with ease. However, while it is powered, it can only store transitory data.

This memory is essential in a computer since it allows you to perform numerous tasks at once. Because each program has its memory, having more RAM will run smoothly simultaneously.

What is Ram’s Purpose?

Assume you’ve switched on your PC. You’re using a word processor while using an internet browser. Memory is used in different ways when you switch between the two programs.

The RAM keeps track of where you are in the browser and remembers what you entered on the word package. The more of these functions you have, the more RAM you’ll need to keep track of where everything was and what it did.

RAM for laptops and desktop computers

Laptops and notebooks use different RAM than desktop PCs due to space limits. The physical device is substantially smaller and has a distinct connecting pin layout.

These are roughly half the size of their desktop counterparts, referred to as DIMMs. This means you won’t be able to swap and change your laptop or desktop memory, and you’ll have to make sure you have the proper one.

Non-Volatile Memory vs. Volatile Memory

Memory is classified as volatile or non-volatile. It loses data when the power is cut. When a program stalls or your machine reboots, you lose whatever you haven’t saved.

Non-volatile memory is the polar opposite of volatile memory. Even if the power goes out, the data will be preserved, and NVRAM is an abbreviation for Nonvolatile Random Access Memory.

Storage and Memory

Although your RAM and hard disc are both memories, they operate completely differently. As a result, you refer to RAM as memory, and the memory itself as storage is frequently easier to explain. When you have a computer, the quantity of memory available is always more than the amount of RAM available.

For example, you might have 1 GB of memory and 16 GB of RAM. The 1 GB is utilized for storage, which means it will save permanent files on your computer. The 16 GB is used for short-term memory and used to run programs.

Latency and speed

The time it takes for a program or command to respond is latency, and it’s linked to RAM because the less RAM you have, you’ll experience greater latency. Understanding the relationship between latency and RAM might help you determine whether or not you need to update.

Is It Necessary to Upgrade My RAM?

RAM will improve your computer’s speed and performance. This is especially beneficial if you’re doing many things at once or if you need a lot of memory. It may be required by graphic designers or gamers to run high-performance apps.

Fortunately, upgrading is simple, and RAM has become more affordable. If you don’t want to do it yourself, talk to a computer memory expert about hiring someone to perform it for you.

RAM’s several types

Different types of computer RAM are available, and the following are a few of the most important.


The Extended Data Out (EDO) feature allows a CPU to access RAM 10 to 15% faster. It accomplishes this by disabling data output drivers. It was updated to BEDO memory in 1995, albeit this is rarely utilized.


Synchronous DRAM gets its name because it syncs with the computer’s clock. It can now run at higher speeds as a result of this. In today’s computers, it’s the most common sort of RAM.

DDR RAM stands for Double Data Rate Memory.

DDR RAM is available in four different varieties, each improving on the previous iteration and providing faster performance. Double Data Rate is the abbreviation for Double Data Rate, and it doubles memory speed by using the system clock.

Purchasing RAM

When you run out of memory on your computer and need to buy more, there are a few things to keep in mind. These might assist you in finding the best fit for your requirements and system.

For starters, 16 GB is now the suggested quantity for most uses. If you use fewer processes, you might be able to get by with 8GB. On the other hand, the additional increase does not come at a high cost.

Check your clock speed to verify if your RAM is suitable as well. There will be no boost in speed if your system supports a lower rate than the memory demands, and things could get a whole lot worse.

Memory on a Computer

If you have trouble running apps and your computer is freezing, you’ll need extra computer memory. Take your laptop to a professional and ask about boosting your RAM. It may also include a CPU or graphics card update to boost overall performance.
