Just like you did with the CPU, it's now time to find out some information regarding the RAM inside of your own local system. The process here will be similiar to how you got that information about your CPU.


Here are some hints for you:

  1. I got excellent results when searching Google for, how to check installed ram on windows
  2. Task Manager shows your RAM information
  3. So does the "System Information" application in the Control Panel


Use the Apple logo and select "About this mac". Here's my MacBook Pro:

"About this mac"

"About this mac"

I have 16 GB of RAM.


This could be a bit more involved, or even easier than the above Windows and macOS processes. It depends on the Linux distribution you're running. You'll have to research this, but here are some tips from inside of a terminal:

  1. free -h
  2. cat /proc/meminfo

Now publish a small article to your Medium blog. Tell us the following:


If you're using a Mac, you'll notice I edited out the serial number of my Mac. I'm not sure if exposing this is a risk, but it feels like it could be. Please make sure you're not publishing information into the public domain, via your Medium account or otherwise, that could identify you or put you at any risk.

  1. The make and model of your laptop or PC (if applicable)
  2. Tell us how much RAM you have
  3. What type is it? DDR3? DDR4? Is it super new and it's DDR5?
  4. Show evidence of your findings.
