    • INTRODUCTION iOS (formerly iPhone OS) is a mobile operating system originally developed for the iPhone later extended to ipad and ipod. iOS is derived from Mac OS X, with which it shares the Darwinfoundation, and is therefore a Unix-like operating system. Apple licenses the trademark for "iOS" from Cisco Systems (who own IOS).
    • HISTORY The operating system was unveiled with the iPhone at the Macworld Conference & Expo, January 9, 2007, and released in June of that year. On March 6, 2008, Apple released the first beta, along with a new name for the operating system: "iPhone OS”. In June 2010, Apple rebranded iPhone OS as "iOS". Apple licensed the "IOS" trademark from Cisco.
    • Version History iOS 1.x: initial OS release iOS 2.x: second major OS release iOS 3.x: third major OS release iOS 4.x: fourth major OS release iOS 5.x: fifth major OS release
    • WORKING PROCESS iOS ARCHITECHTURE
    •  In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The current version of the operating system(iOS 5.0.1) uses roughly 770 megabytes of the devices storage, varying for each model.
    • Cocoa Touch Layer The Cocoa Touch layer contains the key frameworks for building iOS applications. This layer defines the basic application infrastructure and support for key technologies such as multitasking, touch-based input, push notifications, and many high-level system services.
    • Media Layer The Media layer contains the graphics, audio, and video technologies geared towards creating the best multimedia experience available on a mobile device.
    • Core Services Layer The Core Services layer contains the fundamental system services that all applications use. iCloud Storage
    • Core OS Layer The Core OS layer contains the low-level features that most other technologies are built upon.
    • TECHNOLOGIES iPhone iPad iPod Apple Tv
    • iPhone At the Macworld Conference & Expo in January 2007, Steve Jobs revealed the long anticipated iPhone, a convergence of an Internet- enabled smartphone and iPod. . The iPhone features a 3.5-inch (89 mm) touch screen display, 4, 8, or 16 GB of memory, Bluetooth, and Wi-Fi (both "b" and "g"). The iPhone first became available on June 29, 2007 for $499 (4 GB) and $599 (8 GB) with an AT&T contract. On October 4, 2011, Apple unveiled the iPhone 4S.
    • iPad On January 27, 2010, Apple introduced their much-anticipated media tablet, the iPad running a modified version of iOS. Offers multi-touch interaction with multimedia formats including newspapers, magazines, ebooks, textbooks, phot os, movies, TV shows videos, music, word processing documents, spreadsheets, video games, and most existing iPhone apps. On March 2, 2011, Apple introduced an updated iPad model which had a faster processor and two cameras on the front and back respectively.

    • ADVANTAGES Connectivity Reliability Scalability Security
    • DISADVANTAGES Semi-thread message There is no real features upgrade for iPod Unlock way is complicated Mail does not support the attachment directly
    • CONCLUSION Thus, iOS is Apples mobile operating system developed originally for the iPhone later extended to iPad and iPod as well. Apple licenses the trademark for "iOS" from Cisco Systems (who own IOS), the same company with which Apple had earlier settled a dispute over the "iPhone" trademark. iOS 4 is the first version of the OS to be a free upgrade on the iPod touch; Apple had charged $9.99 for earlier upgrades.
