Linux

I know nothing about this topic.
What is it, what does it do, who made it.

Linux is an operating system system.
It was released in 1991
Linus Torvalds was the main guy who created Linux
It is specially made for coding.
It is the third major brand of computers after Apple and Microsoft.

This topic relates to my life because next time I'm going to buy a computer I will think about buying a cheap Linux instead of a expensive mac. Also it said in one site that Linux is made for coders so many of the sites i got to probably have been created by Linux computers.

What makes it a coding computer.
