Best Lightweight Linux Distributions For Older Computers

Brief: Don’t throw your old computer just yet. Use a lightweight Linux distro and revive that decades-old system.

Best light Linux distros

What do you do with your old computers? The one which once had good a hardware configuration but now potentially outdated.

Why not revive your old computer with Linux? I am going to list the best lightweight Linux distributions that you can use on old computers.

Some of the distributions mentioned here are also a part of the best Linux distributions for beginners. So, you might want to check that if you’re new to the Linux universe.

While our focus is on older computers, you can also use most of these lightweight Linux distros on relatively new hardware. This will give you a better performance if you use your computer for resource-heavy usage such as video editing on Linux.

Let’s see which lightweight Linux distribution you can use.
