Describe Apple's closed-source mobile operating system, iOS, and its model of development.

Apple's closed-source mobile operating system, iOS runs on the iPhone, iPad, and iPod Touch. Apple tightly controls the development of the hardware, OS, developer tools, and app deployment platform. Apple's disciplined development model is visible in its strict development policies and controls for third-party developers, and this control contributes to the high level of security in iOS.

Briefly explain what challenge each mobile operating system poses to application developers.

Apple's rigid development model makes it such that your app must pass a rigorous testing program before it is allowed into the App Store. Microsoft's development model, while not typically as rigid, is similar in nature. Google, on the other hand, allows anyone to create Android apps and distribute them to the masses without much interference.

A friend asks you why she would ever disable cellular data networking. Which of the following is not a valid reason to disable cellular data networking? A. You have a limited amount of data in your monthly plan. B. You have access to a reliable Wi-Fi signal. C. You are about to download an update to your phone. D. Your phone calls are going out over your carrier's cellular network.

D. Whenever you have a reliable Wi-Fi signal available, which you do not pay for "as you go," you should feel free to disable your cellular access to data networking. The wireless network is often faster and does not cost you anything to use. If data networking works better when you leave the cellular network available as a fallback, you can choose to disable it only for certain large downloads or disable it completely until the download is complete. Phone calls will continue to be sent over the cellular network. This does not imply that your data is not using an available Wi-Fi connection. Therefore, unless you are particularly sensitive to the situation or know that data is going out over your cell access, you might not need to disable the cellular data- networking feature.
