In 1991, a 22-year-old Finnish graduate student named Linus Torvalds confronted a dilemma. He wanted, but couldn't afford, market versions of Unix:
the powerful and flexible computer operating system sold at $5,000 for the software and another $10,000 for the specialized workstation. (An operating
system, whether Unix, Microsoft Windows, or the Mac OS, is software that lets applications -- like word processors -- use your computer).
