3. Linux: a Product of the Internet
The Linux operating system was developed by a undergraduate student, Linus Tovalds, who used the internet to make his code immediately available to others at no charge.
The system is being developed through the cooperation of many people around the world: it is a product of the internet.

4. The Heritage Of Linux:UNIX
The UNIX system was developed by researchers who needed a set of modern computing tools to help them with their projects.
Unix allowed a group of people working together on a project to share selected data and programs while keeping other information private.

5. The Heritage of Linux: Unix
Linux is Unix work-alike: Someone who is used to using Unix will be right at home with Linux.
In many ways Linux has gone beyond Unix:
* It is more efficient.
* in many case faster.
* has more advanced development tools.

15. Summary The Linux operating system grew out of the UNIX heritage to
become a popular alternative to the traditional systems available for microcomputer(PC) hardware. UNIX system users will find a familiar environment in Linux; Distributions of Linux contain the expected complement of UNIX utilities, contributed by programmers around the world.The Linux community is committed to the continued development of the system. Support for new microcomputer devices and features is added soon after the hardware becomes available, and the tools available on Linux continue to be refined. With many commercial software packages available to run on Linux platforms, it is clear that the system has evolved well beyond its origin as an undergraduate project to become an operating system of choice for academic, professional,
and personal use.
