Google App Engine is a cloud computing platform that allows developers to build and host web applications in Google's data centers. It virtualizes applications across multiple servers and uses a pay-as-you-go model. Key benefits include lower costs, scalability, flexibility, high availability, and a focus on core business needs rather than infrastructure management. It provides libraries, tools, and runtimes for developing applications using popular languages like Java and Python.

5. Fragmentation 2.0 (Eclair) included a new web browser, with a new user interface and support for HTML5 and the W3C Geolocation API. 2.1 (Eclair) 2.2 (Froyo) introduced speed improvements with JIT optimization and the Chrome V8 JavaScript engine, and added Wi-Fi hotspot tethering and Adobe Flash support 2.3 (Gingerbread) 3.0 (Honeycomb) 3.1 (Honeycomb) was announced at the 2011 Google I/O on 10 May 2011. 3.2 (Honeycomb) 4.0 (Ice Cream Sandwich) is said to be a combination of Gingerbread and Honeycomb into a "cohesive whole.” It will be released in Q4 2011.

8. Webkit WebKit is a layout engine designed to allow web browsers to render web pages. WebKit powers Google Chrome and Safari, which in January 2011 had around 14% and 6% of browser market share respectively. It is also used as the basis for the experimental browser included with the Amazon Kindle ebook reader. The WebKit engine provides a set of classes to display web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited.

11. HTML 5 Touch/gestural interfaces — Gestural technology has been implemented by HTML5 framework vendors, such as Sencha. Video/Audio — Now addressed by HTML5 for sustained playback. Audio synchronization for short sound effects still needs work in the browsers. Camera/Video access — HTML5 can handle photo capture from a web page on Android devices (at least on the latest versions, run by the Honeycomb OS; but it can’t handle it on iPhones yet). Contacts access — Here, HTML5 addresses file access, but most apps are beginning to draw from the cloud anyway, and not from the device client. Accelerometer access – HTML5 can handle this. Bluetooth access — This is one device access feature HTML5 has not addressed yet. That said, even for native apps, bluetooth access is fairly limited Disconnected Operation — Web apps through HTML5 can now work in disconnected mode; you can get up to 50MB of database space if you ask user permission, in order to keep operating without an internet connection.
