Having a Linux system on your home computer provides '''access ''' to a large selection of '''open source software'''.<br>

Installing your own version of Linux on your notebook or desktop computer also can make it easier to practice working<br>in the Linux environment and '''learn ''' how to perform routine '''Linux OS administration tasks'''.

''A '''Linux distribution''' (often abbreviated as distro) is an operating system made from a software collection that is based upon the Linux kernel and, often, a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices (for example, OpenWrt) and personal computers (for example, Linux Mint) to powerful supercomputers (for example, Rocks Cluster Distribution)...''

''A live CD (also live DVD, live disc, or live operating system) is a complete bootable computer installation including operating system which runs directly from a CD-ROM or similar storage device into a computer's memory, rather than loading from a hard disk drive. A Live CD allows users to run an operating system for any purpose without installing it or making any changes to the computer's configuration. Live CDs can run on a computer without secondary storage, such as a hard disk drive, or with a corrupted hard disk drive or file system, allowing data recovery.<br><br>As CD and DVD drives have been steadily phased-out, live CDs have become less popular, being replaced by live USBs, which are equivalent systems written onto USB flash drives, which have the added benefit of having write-able storage. The functionality of a live CD is also available with a bootable live USB flash drive, or an external hard disk drive connected by USB.''

The '''Knoppix Live CD''' is available to run on workstations at Seneca College via '''AppsAnywhere '''<br>or you can download and run it on your home computeras a Virtual Machine<br>(requires '''VirtualBox''' VM software installed on your computer).<br><br><!--:''Steps to Run Knoppix from AppsAnywhere(Seneca Labs):''
