The best part is that it is relatively small in size, i.e., 300 MB or even less. Whether you have a PC with modern or outdated hardware, Puppy Linux can be an ideal Linux distro. 

There are three categories of Puppy Linux: 

  • official Puppy Linux distributions
  • woof-built Puppy Linux distributions
  • unofficial derivatives

This distro comes with the most advanced desktop interface. It uses Qt technologies for rendering the widgets and the entire ecosystem.
