The iPad isn't known as a high-end computing device. Most users will buy the iPad Air because of the games and consumer apps like Skype and Evernote. However, there are many advanced apps that use a wealth of back-end data, provide a high-quality video stream, and can handle processing tasks normally reserved for a Windows or Mac computer. Here's a look at eight robust apps with uses as varied as home security, computer-assisted design and stock trading.\nJohn Brandon is a former IT manager at a Fortune 100 company who now writes about technology. He has written more than 2,500 articles in the past 10 years.

After all, the device has a limited amount of memory for local storage, and its mobile processor is designed for email and Web browsing. The Wolfram Alpha app ($2.99) proves you can do real work on a tablet. Thanks to an extensive back end (Wolfram has thousands of servers processing requests), you can search for answers related to mathematics, thermodynamics, physics, chemistry and much more using a simple search field. There's a browsing component as well; you can use the Examples sidebar to create queries and search the vast research archive.More: Is Wolfram Alpha the New Geek Almanac?NGRAIN: 3-D Augmented Reality PlayerThis app, free for NGRAIN Augmented Reality users, provides a 3-D augmented reality overlay on top of a physical object. It might be used to explain how to fix a part in a vehicle or overlay a medical drawing over a piece of human anatomy. The app uses millions of data points, or voxels, that are fed to the iPad in real-time. Each voxel can contain measurements, such as the temperature of the object or size. The diesel pump shown at left consists of 376 parts and 1.2 million polygons \u2014 yet NGRAIN manages to reduce this massive CAD image down to about 7MB to work on the iPad.More: Top 15 Augmented Reality Apps for iOSNew Relic: Track Website TransactionsThis app gives you access to the New Relic service (free), which tracks website transactions and back-end application activity in real time.
