Linux. From its original concept way back in 1991, to its near world domination in 2013, Linux has travelled far as an operating system and as a symbol of freedom.
You can now find Linux on every type of hardware from mainframes to mid-range servers to desktops to tablets to cell phones and down to miniature computing devices such as the Arduino. There’s really no limit to what Linux can do or has done for technology.
Its positive impact on computing cannot be denied.
