===Installing Linux===
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'''.
[[Image:distro-1.png|thumb|right|450px|Listing of Common Linux Distributions.<br>(Image licensed under [https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
''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...''
Reference: https://en.wikipedia.org/wiki/Linux_distribution
''Steps in the Linux Installation Process:''
* '''Select''' a ''Linux Distribution'' to '''download''' (ISO image file or VM file).
* '''Create''' VM and '''install''' Linux Distribution or '''run''' VM file.

===Linux Installation Methods===
[[Image:stand-alone.png|thumb|right|250px|Linux is the only OS on the computer<br>(Image licensed under [https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
'''Standalone Installation'''
: Linux is the <u>only</u> OS on the computer.
: Any existing data on your hard disk will be '''erased'''.
[[Image:grub-boot-menu.png|thumb|right|250px|The '''grub boot menu''' to select different operating systems upon computer startup.<br>(Image licensed under [https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
'''Dual-boot / Multi-boot Installation'''
: A '''boot menu''' allows the user to select the desired OS.<br><br>
: '''Advantages''' of Dual-Boot or Multi-Boot:<ol><li>This option provides a method to access your computer if one OS '''fails to boot-up'''.</li><li>'''Access the Windows partition''' if your Windows OS cannot boot-up.</li><li>This booting method is great for '''troubleshooting'''<br>(''for example:'' boot into Linux OS to eliminate a hardware issue).</li></ol>
: '''Installation Tips:'''<ol><li>It is recommended to '''back up important data''' before proceeding.</li><li>It is recommended to '''install the Linux OS <u>last</u>''', as other operating systems may not offer a multi-boot option.</li></ol>
'''Virtual Machine Installation'''
[[Image:vm-player-menu.png|thumb|right|250px|VMware Player launch menu for Ubuntu Linux OS<br>(Image licensed under [https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
: ''Virtualization is the process of running a virtual instance of a computer system in a layer abstracted from the actual hardware.'' Reference: https://opensource.com/resources/virtualization
: The virtualized OS is installed and run in a window under another OS. Special software is used to manage the entire process, referred to as the '''hypervisor'''.<br><br>
: '''Advantages''' of Virtualization:<ol><li>You can run VM from an '''ISO image file''' or a '''VM file'''.</li><li>One or more virtual machines can be run at the <u>same</u> time.</li><li>The '''guest''' OS '''shares hardware''' with the '''host''' OS and possibly other virtualized systems.</li><li>The '''guest''' systems have '''network access''' through the host.</li></ol>
: '''Installation Tips:'''<ol><li>Virtualization requires a '''compatible processor''': not all processors support that feature.</li><li>Your '''BIOS''' should be set to '''<u>enable</u> Virtualization'''.</li><li>Popular VM software for '''Windows''', '''Apple''' and '''Linux''' OS include:<ul><li>VMware</li><li>Oracle Virtual Box</li></ul></li></ol>

===Live Linux CD===
[[Image:linux-distro-2.png|thumb|right|150px|Knoppix is a popular Live Linux CD Distribution.<br>(Image licensed under[https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
''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. ''
Reference: https://en.wikipedia.org/wiki/Live_CD
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 computer as a Virtual Machine<br>(requires '''VirtualBox''' VM software installed on your computer).<br><br>

===Installing Linux===
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'''.
[[Image:distro-1.png|thumb|right|450px|Listing of Common Linux Distributions.<br>(Image licensed under [https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
''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...''
Reference: https://en.wikipedia.org/wiki/Linux_distribution
''Steps in the Linux Installation Process:''
* '''Select''' a ''Linux Distribution'' to '''download''' (ISO image file or VM file).
* '''Create''' VM and '''install''' Linux Distribution or '''run''' VM file.

===Linux Installation Methods===
[[Image:stand-alone.png|thumb|right|250px|Linux is the only OS on the computer<br>(Image licensed under [https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
'''Standalone Installation'''
: Linux is the <u>only</u> OS on the computer.
: Any existing data on your hard disk will be '''erased'''.
[[Image:grub-boot-menu.png|thumb|right|250px|The '''grub boot menu''' to select different operating systems upon computer startup.<br>(Image licensed under [https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
'''Dual-boot / Multi-boot Installation'''
: A '''boot menu''' allows the user to select the desired OS.<br><br>
: '''Advantages''' of Dual-Boot or Multi-Boot:<ol><li>This option provides a method to access your computer if one OS '''fails to boot-up'''.</li><li>'''Access the Windows partition''' if your Windows OS cannot boot-up.</li><li>This booting method is great for '''troubleshooting'''<br>(''for example:'' boot into Linux OS to eliminate a hardware issue).</li></ol>
: '''Installation Tips:'''<ol><li>It is recommended to '''back up important data''' before proceeding.</li><li>It is recommended to '''install the Linux OS <u>last</u>''', as other operating systems may not offer a multi-boot option.</li></ol>
'''Virtual Machine Installation'''
[[Image:vm-player-menu.png|thumb|right|250px|VMware Player launch menu for Ubuntu Linux OS<br>(Image licensed under [https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
: ''Virtualization is the process of running a virtual instance of a computer system in a layer abstracted from the actual hardware.'' Reference: https://opensource.com/resources/virtualization
: The virtualized OS is installed and run in a window under another OS. Special software is used to manage the entire process, referred to as the '''hypervisor'''.<br><br>
: '''Advantages''' of Virtualization:<ol><li>You can run VM from an '''ISO image file''' or a '''VM file'''.</li><li>One or more virtual machines can be run at the <u>same</u> time.</li><li>The '''guest''' OS '''shares hardware''' with the '''host''' OS and possibly other virtualized systems.</li><li>The '''guest''' systems have '''network access''' through the host.</li></ol>
: '''Installation Tips:'''<ol><li>Virtualization requires a '''compatible processor''': not all processors support that feature.</li><li>Your '''BIOS''' should be set to '''<u>enable</u> Virtualization'''.</li><li>Popular VM software for '''Windows''', '''Apple''' and '''Linux''' OS include:<ul><li>VMware</li><li>Oracle Virtual Box</li></ul></li></ol>
<br>
===Live Linux CD===
[[Image:linux-distro-2.png|thumb|right|150px|Knoppix is a popular Live Linux CD Distribution.<br>(Image licensed under[https://creativecommons.org/licenses/by-sa/3.0/ cc])]]
''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. ''
Reference: https://en.wikipedia.org/wiki/Live_CD
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 computer as a Virtual Machine<br>(requires '''VirtualBox''' VM software installed on your computer).<br><br>
