Apple iOS4

    Multitasking

The biggest and most obvious update to iOS 4 is the ability for third-party applications to "multitask"—that is, you don't have to terminate them in order to do something else in another app. This is functionality that has been requested of Apple since the launch of the original iPhone in 2007, and it has been a long time coming.Apple's own apps have always been able to truly multitask ,but third parties can now take advantage of a limited set of multitasking capabilities in order to make things easier on the user.

Apple iOS 4's Hidden Features

Home Screen

As usual, Apple snuck a number of new features into almost every facet of iOS, so let's start with the first thing that most people see when they use an iPhone: the Home screen. Now, you probably already know about the major new features like folders for organizing apps and support for wallpaper backgrounds (just like the iPad feature), but we've found a couple more perks as well. First, the Spotlight screen now offers "Wikipedia" and "Web" options at the bottom of your search results. If you don't find what you're looking for locally, these are two easy launchpads for taking your query out to the Web.

Abstract

 iOS is Apple's mobile operating system developed originally for the iPhone, and later deployed on the iPod Touch and iPad as well. It is derived from Mac OS X, with which it shares the Darwin foundation, and is therefore a Unix-like operating system, by nature. In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The operating system uses roughly 500 megabytes of the device's storage.
