Best Lightweight Linux Distros of 2020

In this guide, let’s discuss Lightweight Linux Distros available for PCs with older hardware configuration. A lot of tech enthusiasts happen to own a computer system that is almost a decade old. If we look at the hardware evolution in the tech world, we have come a long way. The cost of an Intel Core i5 chip-based computer that used to cost around $600 7 years ago, is now costing over $1000. That itself says, how computer hardware has evolved rapidly. The software has also evolved accordingly.

The question that comes to the mind is, what if someone owns any old hardware assemble of PC.? Most likely it won’t run the latest software. Then is there a way to use these machines or simply discard them for being obsolete.? Various lightweight Linux Distros can be the answer to all these questions.

I have listed some Linux Distros that can still make an older system run fine enough. I have briefly described the Distros and also mentioned their system requirements. Even though the hardware setup of your PC may be a tad older, these Linux OS can work efficiently with the hardware. When I say older hardware, you can think of the decade-old Pentium chipset based PCs or even older than that. The requirement of memory is also minimal. Some of the distros also have an advanced variant that you can use on more modern systems that are less than a decade in age.
