What’s an Operating System?

Here’s an operating system choice you might be familiar with…

How Unix came to be • Originated with Bell Labs in the 1970 s • AT&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 Internet ALWAYS concerned with efficiency Oriented around well defined processes Not concerned with easy of use Not concerned with a slick User Interface It’s the OS on your web server and on your router Variants of it are on your phone, and on your game system • In short, it’s the OS made by techies, for techies. • • •

The Rise of Linux • In 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 x 86 processor) and it was a completely open source product.

Distributions of Linux • • Debian Red Hat SUSE Ubuntu Although 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.

Where should I start? … Ubuntu and you • Ubuntu 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 stack • The 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, My. SQL, and PHP. )
