1Whats an Operating System?

Heres an operating system choice you might be familiar with

How Unix came to beOriginated with Bell Labs in the 1970sAT&T licensed Unix to outside parties, both academic and commercial.Alternative to other exotic operating systems of the day OS/360, Unisys, Data General

Why Unix is the OS of the InternetALWAYS concerned with efficiencyOriented around well defined processesNot concerned with easy of useNot concerned with a slick User InterfaceIts the OS on your web server and on your routerVariants of it are on your phone, and on your game systemIn short, its the OS made by techies, for techies.The Rise of LinuxIn 1991, while attending the University of Helsinki, Linus began to work on his own operating system kernel, which eventually became the Linux kernel.The big deal was that this operating system could run on commodity hardware (and Intel x86 processor) and it was a completely open source product.

Distributions of LinuxDebianRed HatSUSEUbuntuAlthough Linux distributions are generally available without charge, corporations do contribute to the development of the components of the system. Roughly 75 percent of the code for Linux comes programmers working for corporations.

A number of corporations have built a significant business around Linux support.

Major corporations that provide contributions include Dell, IBM, HP, Oracle, Sun Microsystems (now part of Oracle), SUSE, and Nokia.

11Where should I start? Ubuntu and youUbuntu has earned a reputation for being relatively easy to install and use.It is Debian based.Development of Ubuntu is led by UK-based Canonical Ltd., a company owned by South African entrepreneur Mark Shuttleworth. The Ubuntu project is publicly committed to the principles of open-source software development; people are encouraged to use free software, study how it works, improve upon it, and distribute it.The LAMP stackThe appeal of Linux is the services it can provide, at zero licensing cost.Some applications are bundled together so frequently that they are know collectively as a stack.The most popular stack is the LAMP stack (Linux, Apache, MySQL, and PHP.)
