Step-by-step explanation:
Linux is an example of open-source software. It was developed by Linus Torvalds, a Finnish graduate student, in 1991. Linux rapidly gained popularity due to its free distribution and easy configurability. It became especially useful for running file servers and internet routers, replacing expensive proprietary systems. The development of open-source operating systems like Linux changed the economics of high tech by providing an alternative to costly proprietary systems and reducing dependence on specific manufacturers.
