“Linux is an alternative computer operating system founded
nearly a decade ago by Finnish computer programmer Linus Torvalds.
It’s similar to Unix, another operating system that is a popular
Microsoft Windows NT rival.”
“Many computer programmers are excited about Linux because its
source code is freely available. This means programmers can easily
make changes to their software applications (which, in turn, means
their software runs optimally.) Linux’s availabilty helps make it
extremely reliable and stable (thus, its popularity among Web
developers and Internet Service Providers)….”
“The key challenge? Whether Linux actually can build
significant market share and allow companies to make money off
‘free’ software.“
