Using Linux On Old Hardware
The best thing about Linux OS is that it can be used on any hardware. Linux OS is not restrained by specific requirements of any kind of hardware.
Therefore, before throwing away your older and almost useless computers and computer parts, give them a second chance.
The older computers can be easily used by installing lightweight Linux OS. Lightweight Linux OS will give breathe life into these older models. Lubuntu, Puppy Linux, Bodhi Linux, Linux Lite, Tiny core, are good examples of Linux OS for older computers.
