Origin of Linux:

Linux is a unique operating system, which was born, grew and matured in the network. 199 1 year, Linus Torvalds, a Finnish college student, came up with the idea of developing a free UNIX operating system. That year, Linux was born. In order not to let this fledgling operating system die, Linus released his own work Linux through the Internet.

Since then, a large number of well-known and unknown computer hackers and programmers have joined the development process, and Linux has gradually grown up.

At the beginning, Linux required that all source code must be made public, and no one could profit from the Linux transaction. However, this ideal of pure free software is not conducive to the popularization and development of Linux, so Linux began to turn to GPL and became the main member of GNU camp.

With excellent design, extraordinary performance and strong support from internationally renowned companies such as IBM, INTEL, CA, CORE and ORACLE, Linux has gradually expanded its market share and become one of the mainstream operating systems.
