Unformatted text preview: on a microkernel so that it can be easily ported to many
different types of machines, and its features can be easily enhanced by users.
8. It is a true 32-bit operating system in the sense that it can make full use of the
32-bit architectures of the processors and the memory and I/O bus to provide fast
Linux is an open-source operating system enhanced and backed by thousands of
programmers world-wide. It is a multi-tasking operating system that was
originally designed to be used on personal computers. The name "Linux" is
derived from its inventor Linus Torvalds. Linus was a student at the University of
Helsinki, Finland in early 1990s when he wrote the first version of a Unix-like
kernel as a toy project. He later posted the code on the Internet and asked
programmers across the world to help him build it into a working system. The
result was Linux. Torvalds holds the copyright, but permits free distribution of the
source code. That is, he oversees development of the kernel and owns its
trademark. When someone submits a change or a feature, Torvalds and his core
team of kernel developers review the merit of adding it to the source code.
Linux Development Process
Linux being an open-source operating system, various parties are involved in its
development process. The key roles played by the various participants are as
The open-source development community (programmers across the world)
develops the source code for the operating system kernel and submits it to the core
team of kernel developers headed by Torvalds. This team reviews the merit of adding the submitted change or feature in the kernel and incorporates it into the
kernel if so decided. This is how the kernel evolves and matures to become better
2. Application vendors and programmers download the freely available kernel
and develop all typds of application software for it.
3. Distribution companies package and sell various Linux versions.
4. Hardware vendors bundle Linux on their systems and supply their systems
along with the Linux op...
