History
(cid:73) The Linux kernel is one component of a system, which also
requires libraries and applications to provide features to end
users.
(cid:73) The Linux kernel was created as a hobby in 1991 by a Finnish
student, Linus Torvalds.
(cid:73) Linux quickly started to be used as the kernel for free software
operating systems
(cid:73) Linus Torvalds has been able to create a large and dynamic
developer and user community around Linux.
(cid:73) Nowadays, hundreds of people contribute to each kernel
release, individuals or companies big and small.
