Operating Systems
• Operating systems (OSs)– Windows– MAC OS– UNIX

Why do bioinformaticians NOT like Windows?
• OS is NOT free
• Applications are NOT free
• The OS uses too much CPU and RAM resource
• Command-line is too simple to support automated data processing

Why do Bioinformaticians prefer Mac or UNIX over Windows?
• Better development environment
• Software availability
• Powerful command-line interface (terminal)
To really learn bioinformatics (regardless of whether you’re a “biology student”), you need to become familiar with a “*nix” environment and the tools that it provides

UNIX & Linux
• There are many different versions of UNIX, although they share common similarities. The most popular varieties of UNIX are Sun Solaris, GNU/Linux, and MacOS X
• Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution. The Linux kernel was written in 1991 by Linus Torvalds

Ubuntu: one of the mostpopular desktop Linux Distro
Linux distributions take the Linux kernel and combine it with other free software to create complete packages

Two distinct UNIX environments
• Large/super computer cluster
• Individual Linux desktop/workstation

MAC users
• MAC OS is essentially Unix based and has built-in terminal.
