• Sims is a virtual world
• You can have virtual profiles on the internet
• Virtual is something that is not in shape (you cannot touch it)

1. What is virtualization
2. How does the use of virtualization affect people around the world. 

-Links to where you found the most useful information (at least 2, NOT Wikipedia, although you can use it to help you)

• to create a virtual version of a device or resource, such as a server, storage device, network or even an operating system where the framework divides the resource into one or more execution environments. http://www.webopedia.com/TERM/V/virtualization.html
• This link talkes about how industries should convert into virtual world because it would have a larger impact on more people. http://www.itworld.com/nls_windowsserver050411
• This link might seem as very unreliable (for dummies) though it really sais, in simple worlds, why virtualization is important for saving money, energy, and space. http://www.dummies.com/store/product/Virtualization-For-Dummies.productCd-0470148314.html

-Bullet list of things you learned about the topic (at least 5)

• Analogy taken from http://itknowledgeexchange.techtarget.com/virtualization-pro/several-ways-to-explain-virtualization-to-a-non-techie-person/Imagine you are a parent of four teenage daughters. All your life you have wanted to provide your daughters with their very own “resources,” like their own bedrooms, their own bathrooms, their own computers, their own clothes, etc., but you just could not afford to do it.What if I could tell you how to give them all everything they wanted and they really believed that they each had their own bedrooms and bathrooms, but in reality you only had to build one bedroom and one bathroom? You would be well within your budget, your daughters would be very happy, and you would not be using space, materials and money to build all those separate rooms. 

This is an analogy taken from the same webpage, where you can see the idea por virtualization in a more precise way.  

In the past, the server was a like a very expensive hotel. It was the worst kind of hotel. It only had one big room and only one person could stay there. However, all employees, whether they were the CEO or copy-boy, had to stay there if they were away on business.

This is like the guest operating system being installed to a physical server. Half the time the occupant is out doing other things, asleep, or just lying on the bed surfing up and down the channels looking for the type of channels his wife wouldn’t let him have at home. This is like when Linux or Windows is idling and only using 5% – 10% of CPU or memory. It became considered too costly to build such hotels and filling them with one occupant was very wasteful – because they consume heat, water and power – and most of the time the single occupant either wasn’t there or was asleep!

So someone had the idea of a better hotel, one which was divided into a series of different rooms. Each could be different sizes and offer different qualities of service. It didn’t matter what one guest did in one room, as it could not affect others. This hotel had really thick sound insulation so you couldn’t hear the wedding party downstairs or the newlyweds doing newlywed things next door.

On the top floor beyond the bridal suite, were the penthouse suites which were reserved for the high rollers, specifically for Mr. Exchange, Miss, SQL and Mrs. SAP – but in other floors the rooms were barely large enough to swing a small furry animal – this is where Mr. DHCP and Dr. DNS resided. The old hotel was so expensive only people like Howard Hughes could afford a room there – but this new, more efficient, hotel cost the same to build and maintain – and everyone could find a room that was suitable for their needs – from the odd billionaire to the business man on an overnight stay before catching a flight. It also meant we had to build fewer hotels.

The other thing we discovered was when Mr. Exchange or Miss SQL weren’t around or sleeping – as they were consuming less resources – their resources could be divvied out to the residents in the hotel to improve their experience. It would be easier to get that table in the fancy restaurant, and it was quicker to get served in the bar. Finally, the old hotel model died a swift and untimely death when the economy fell off the end of a cliff. It became increasingly regarded as a luxury no company could afford. The Hotel Virtualization model ruled the roost because it offered the most flexible model of accommodating guest operating systems with their wildly different resource demands.

•  People can do something virtual and gain money as well as time. Since it is easy to access and understand, it can satisfy many peoples needs
• The using of virtualization involves less resources for the same or better result.

-A short summary of how this topic connects/relates to you or your life

Virtualization is a big part of my life, as well as the wold in general. We are constanty connected to different servers, all composed by virtual influences. Propaganda on the interntet is a large part that happens while we are connected. We are affected by this even in a way that we dont know. Stimulation  on the internet can lead you to a larger personal development (positive or negative).

IS THERE A WAY TO HAVE A CLEAR IDEA OF THIS?

I don't feel I understand this idea completely.
