CS 101 Different Operating Systems

Software • Software is a set of instructions for the computer to follow to accomplish a task. • Operating System = Set of instructions that controls all hardware and software on the computer

Reasons For Other OS’s • Security = Move away from herd • Some software only runs in certain OS’s • Can make upgrading OS’s less scary • Access to OS’s specific features and apps

Four most popular current desktop operating systems • 1 Windows • 2 Macintosh OS X • 3 Linux (we use the Ubuntu version in lab) – Ubuntu (you can try before you install) • 4 Chrome OS (Not the web browser. Usually on a Chromebook. )

Ways to use different OS’s • Multi-Boot Computer • Use On Old Outdated Computer • Virtual Computer

Multiple Boot Computer • What is it? – You create multiple partitions on your hard drive. – You install different operating systems on different partitions. – Pick out which OS to use when computer starts up,

Multiple Boot Computer • Pros: – Fastest way to run another operating system. • Good for gaming – Cheap (Linux is free). – Can run less popular operating system on your computer to access the Internet more securely. – Can run Windows only software in a Mac. • Cons: – Partitioning a drive is risky (make sure to have complete backup in place before attempting). – Need to reboot computer to use other operating system. – Need a Windows license. $

Multiple Boot Computer • How is it done? (Warning: Have a complete backup before you partition your drive. ) – Putting Windows on a Macintosh computer. • Get Windows with license. Run the Apple Boot Camp Assistant program located in the Utilities folder. It will step you through the process of installing Windows. – Putting Mac OS on a Windows computer. • Not legal to do. – Putting Ubuntu on a Windows or Mac computer follow directions here: • https: //www. ubuntu. com/download/desktop/install-ubuntu-desktop

Install OS On Old Computer • What is it? – You can take an older Mac or Windows computer and give it new life by installing a different operating system.

Install OS On Older Computer • Pros – – Great way to use an older computer that is considered unusable. Can buy a cheaper, older computer instead of a new expensive one. OS is free. Increased security. • Cons – None

Install OS On Older Computer • How is it done? • Putting Ubuntu on an older computer. – Follow Ubuntu directions here: » https: //www. ubuntu. com/download/desktop/install-ubuntu-desktop

Virtual Computers • What is it? – You install software that allows you to create virtual operating systems on your computer. – You can then run multiple operating systems on your computer at the same time. – You can create as many virtual operating systems as you have room on your hard drive.

Virtual Computers • Pros: – No need to reboot computer to use other operating systems. – Can use less popular operating system to access Internet for more security. – Can access Mac/Windows at same time as virtual OS. – Do not need to partition hard drive. • Cons: – Slower way to run another operating system. • Not as good for gaming – May have to pay for virtualization software.

Virtual Computer On A Windows or Mac • How is it done? – First you install the virtual software • Parallels Desktop $50 - 80 • VMware Fusion $50 - 80 • Virtual. Box $Free – Then create new virtual operating systems. – Open and run as many operating systems as your computer is capable.

Easiest and Free Way To Install Ubuntu on Windows or Mac • Download and Install Virtual Box • Download Ubuntu image • Ubuntu • Run Virtual Box and install Ubuntu as guest OS

Feel free to bring your computer to the second half of any of my labs for help installing other operating systems.
