One of the common reasons why people switch to Linux is to be able to continue using a computer that no longer supports the latest versions of Windows or MacOS. How good is Linux for this job and why?
Linux is efficient: many Linux distributions are based on years of experience in server rooms. System administrators often appreciate smooth, clean code that gets the job done without losing power. The extra five seconds to turn on the system is something many system administrators are not willing to put up with. Because of this harsh and demanding environment, Linux distributions have become the best of their kind. Although with software coming from many different sources, it’s not the case that every program will make the best use of system resources.
Linux is customizable: Linux allows users to customize every aspect of the computer’s functionality. Some distributions recommend choosing different components and building your own system. Most of them provide all the work, but allow you to change or modify parts as you wish. Many distributions encourage you to make your own adjustments, while setting up others (such as an elementary OS) may require more specialized knowledge.
Linux requires no investment: the vast majority of Linux programs are free to download and install. These programs are usually quite easy to use so you do not need to spend money on training courses or books. All you need to spend to revive an old computer with Linux is time.
Linux is modular and specialized: you can set up a computer which is specifically designed to meet your needs: remote video control, a database of food recipes, a control panel for an amazing laser projector which changes intensity in sync with the beat of the music. You can build anything you want. Proof of the quality of modular Linux design is the version of Red Hat Linux that was used to control the electromagnets inside the Large Hadron Collider. You will be surprised how many things your old computer can still do.
