1 - Perello Presentation 1/17/2019 4

Remote computing Need to compute “out there” Need for separate local processor. 1/17/2019 5

Local Computing Choices Separate processor. Separate virtual operating system. 1/17/2019 6

2 – Virtual Operating Systems 1/17/2019 7

Sloppy Language Language of “virtual operating system” is sloppy. VOS Virtual machine application Virtual operating system Both Virtual Machine 1/17/2019 8

Definition OF VMA, VOS A virtual machine application is an application that simulates one or more virtual operating systems. A virtual operating system is an OS that has been “installed” on a virtual machine application. A virtual operating system is not a dual boot. A user has the same experience using a virtual OS as he has using a host OS. 1/17/2019 9

Hierarchy Host operating system – e.g. Windows 10 Virtual machine application – e.g. VMWare Virtual OS – e.g. Windows XP, Linux 1/17/2019 10

Reasons To Use A Virtual OS Require different development environment. Windows 10, Windows XP, Ubuntu Run application available on different OS. Windows 7 backup Customize computing environment. Spouse, children, guest Isolate computing. Unsecure Internet access Test new OS. 1/17/2019 11

Requirements Licensed virtual machine application Licensed OS installation media Sufficient CPU Sufficient memory Sufficient disk space 1/17/2019 12

Process Download virtual machine application. (1 time) Install virtual machine application. (1 time) Start virtual machine application. Install virtual operating system. (1 time) Launch VOS. 1/17/2019 13

VMWare Create a new virtual machine Installer disc ISO file Later ISO file from Ubuntu web site ISO file from Microsoft web site Later 1/17/2019 25

VMWare Open a new virtual machine Refer to left panel. Choose from installed VOS’s. 1/17/2019 26

Ubuntu ? 1/17/2019 27

Windows 8 Proof 1/17/2019 28

Windows 8 Access to host hard drive Share hard drive on host OS. Map to hard drive on virtual OS. Access to host printer Share printer on host OS. Map to printer on virtual OS. 1/17/2019 29

Windows 8 Access to host applications NO ACCESS! Non-portable applications have to be reinstalled on VOS. 1/17/2019 30

Windows 8 Access to network resources Access is the same as any other OS. Map to shared printer. Map to shared folders. 1/17/2019 31

5 – Conclusion You have had a high level introduction to virtual operating systems. A virtual operating system is a very useful tool in your toolbox. Your next step is trial and error. 1/17/2019 32
