In other words, Android users think a lot of ‘open platform’ rather than the brand Google。河北大學(xué) 21012屆本科畢業(yè)生外文文獻(xiàn)翻譯 1ESEP 2021: 910 December 2021, Singapore An Analysis and Comparison of Open and Closed Mobile Platforms Android vs. iPhone Yinglu ZOUa,?, Hao WU b, Jianxin HUANG a,b a Information Engineering College,7 JianXue Road, JinShui District, ZhengZhou, 450001, China Abstract With the release of Android Froyo and iPhone 4, the war between open and closed mobile platforms tends to befiercer. Being the representatives of the two parties, Froyo and iOS 4 are quite different at system framework, newfeature, application market and integration model. According to the pany spirits of Google and Apple, we do some analyses and parisons of the above points, explain the differences of Android and iPhone from the shallower to the deeper, then conclude the characteristics of open and closed mobile platforms, aiming at providing an objective reference for researchers of mobile platforms, helping them see clearer into mobile industry. As a result,both Froyo and iOS 4 have their advantages and disadvantages, still they are far from being perfect, there’s room forfurther improvement. Keywords: Android； iPhone； Froyo； iOS 4； smart phone； mobile platform 1. Introduction In recent years, the popularity of smart phone kept going up. More and more smart phones are sold anda lot of people are embracing them. Smart phones brought great convenience to users, as well created opportunities for smart phone researchers. That’s to say, the wide spread of smart phones benefited both sides. At the same time, developing of smart phone OS bees one of the smartest industry. To be a smart phone OS, the system should: 1. Provide services like a PC. 2. Work with a GPU for better visual effects. 3. Allow the user to surf on Inter freely. And apparently, there’re also some weaknesses: battery. 2. Poor CPU performance against PC CPU. 3. Small storage. 4. The use of RAM may leads to loss of data when the phone runs out of battery 河北大學(xué) 21012屆本科畢業(yè)生外文文獻(xiàn)翻譯 2 Now the 2 giants of smart phone OS are Android and iPhone OS. On one side, Android is based on Linux kernel and Dalvik virtual machine, and it is open sourced. The upper layer of Android is Java based,allowing developers to develop Android applications with Google SDK and sell their software in Android Market. On the other side, iPhone OS, which bases on Unix kernel and Darwin model but is closed sourced,evolves from Mac OS X and is the default OS of iPhone, iPod Touch and iPad. Objective C based software can run in iPhone OS, and just like Android, you can develop your own iPhone applications and upload them onto Apple’s ‘App Store’ for sale [1] [2] [3] [4]. By paring the latest Android and iPhone OS, Android Froyo and iOS 4, we can take a glimpse at the main feature of open and closed smart phone OSs. While the 2 OSs are designed in rathe
