TRY this....

MAGIC #1

Found that nobody can create a FOLDER anywhere on the Computer which can be named as "CON". This is something funny and inexplicable? At Microsoft the whole Team, couldn't answer why this happened! TRY IT NOW, IT WILL NOT CREATE A "CON" FOLDER

MAGIC #2

For those of you using Windows, do the following:
1.) Open an empty notepad file
2.) Type "Bush hid the facts" (without the quotes)
3.) Save it as whatever you want.
4.) Close it, and re-open it.
Noticed the weird bug? No one can explain!

MAGIC #3

Again this is something funny and can't be explained?
At Microsoft the whole Team, including Bill Gates, couldn't answer why this happened!
It was discovered by a Brazilian. Try it out yourself?
Open Microsoft Word and type
=rand (200, 99)
And then press ENTER And see the magic?..!

Magic #4

Did you know that a flight number from one of the planes that hit one of the two WTC towers on 9/11 was Q33N. In Notepad / WordPad or MS Word, type that flight number i.e Q33N. Increase the font size to 72. Change the font to Wingdings. ..... u will be amazed by the findings!!!

Introduction to Cloud Computing

In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. It goes back to the days of flowcharts and presentations that would represent the gigantic server-farm infrastructure of the Internet as nothing but a puffy, white cumulonimbus cloud, accepting connections and doling out information as it floats.

What cloud computing is not about is your hard drive. When you store data on or run programs from the hard drive, that's called local storage and computing. Everything you need is physically close to you, which means accessing your data is fast and easy, for that one computer, or others on the local network. Working off your hard drive is how the computer industry functioned for decades; some would argue it's still superior to cloud computing, for reasons I'll explain shortly.

The cloud is also not about having a dedicated network attached storage (NAS) hardware or server in residence. Storing data on a home or office network does not count as utilizing the cloud. (However, some NAS will let you remotely access things over the Internet, and there's at least one NAS named "My Cloud," just to keep things confusing.)

For it to be considered "cloud computing," you need to access your data or your programs over the Internet, or at the very least, have that data synchronized with other information over the Web. In a big business, you may know all there is to know about what's on the other side of the connection; as an individual user, you may never have any idea what kind of massive data-processing is happening on the other end. The end result is the same: with an online connection, cloud computing can be done anywhere, anytime.
