What does Linux cost? Are there licensing fees?
The Linux kernel software is free – but the kernel software by itself is not a functional operating system. To make a complete system there is considerable additional software required. Fortunately, there are companies and groups that do this and release it to the public as a distribution which can then be installed and run. The cost of distributions varies from free to hundreds of dollars and come with varying levels of support – from zero to 24/7/365 enterprise support.
