Can some one explain to me ,how Cloud works with ipad?

When I updated my ipad to ios 5.1.1, i have downloaded the cloud as well,with out knowing about its usage, I would be glad ,if someone could explain to me how it works with ipad or desktop or laptop? Or about its importance?

The use of the term "cloud" refers to a technology - the storage of data online which is "pushed" to internet connected devices. I believe that you are specifically referring to Apple's "iCloud," which is Apple's implementation of "cloud" technology. 

Logos utilizes "cloud" technology. When 1) your computer is online and 2) your installation of logos is signed in, Logos automatically downloads new updates. When you purchase new resources, they are "pushed" to your computer... you do not need to "ask" it to do so.

Apple uses iCloud in similar ways, but it is much more beneficial to those who are in the Apple ecosystem (using Mac; iPad; iPhone; Apple TV). Your music, calendar, email, iWork documents, are "pushed" to all devices.

MacWorld has "iCloud: What you need to know" => http://www.macworld.com/article/160380/2011/06/icloud_what_you_need_to_know.html

Review of iOS 5 includes iCloud on pages 7 (Apps) => http://www.gsmarena.com/apple_ios_5-review-657p7.php and 8 (sync stuff) => http://www.gsmarena.com/apple_ios_5-review-657p8.php

From another web site, learned iCloud does not sync documents with Windows => http://office-watch.com/t/n.aspx?a=1618 (can use web interface to drag and drop documents).  Also iCloud has problems with Outlook => http://office-watch.com/t/n.aspx?a=1620&z=0

13 Oct 2011 review compares iCloud, Google Apps, and Office 365 => http://www.boxfreeit.com/Productivity/icloud-vs-google-apps-vs-office-365.html

Appears iCloud is attractive for use with Apple's office suite (iWorks) on Apple devices, but lacks collaborative editing between different people.  Currently, Apple's Pages can export to Word doc format that requires conversion to docx for use in Logos 4 as a Personal Book.
