Apple iOS (Closed Source)
Apple’s iOS is an example of closed source software. Previously known as the iPhone Operating System, it is now simply referred to as iOS because it is used on iPhones and iPads as well. It is

based on Mac OS X (used on Mac desktops and laptops) and is therefore effectively UNIX based. Only Apple devices can run iOS.
To find out the version of iOS you are running, go to the Home screen, then tap Settings. Tap General, and then tapAbout. You will see the version number. For example, Figure 8-2 shows aniPad2 running version 5.0 (9A334). 9A334 is the build number; this was the public release of ver-sion 5.0.

Getting Applications for Your Device
Android users download applications from the Android Market (also accessible through Google Play.) This can be done directlys from the mobile device. Or, if a mobile device is connected via USB to a computer, the user can browse apps on the Google Play website while working on the computer and download directly from the site to the phone, passing through the computer.
iOS users download applications from the App Store. This was originally an update to the iTunes store, but on newer iOS mobile devices it is now a separate icon on the Home screen. Apps can also be downloaded from a Mac, or from a PC through the iTunes application.
