Google offers apps for its Android mobile operating system through its Android Market. And many companies directly sell apps for use with their products. For example, General Motors has developed an app that gathers information about its new hybrid car, the Chevy Volt.
FAITH LAPIDUS: University professors in computer sciences have a good idea about the growing number of apps that are becoming available. Many professors offer classes in which they guide computer engineering students in building apps. Some of the resulting products have been very creative and gained popularity.
Marc Buchner is an associate professor of computer science and electrical engineering at Case Western University in Cleveland, Ohio. He says apps are really nothing new.
MARC BUCHNER: “Applications, or apps, are really short for application programs. And these are the things that run on computers: your pc’s, your macs, and run on mobile devices such as iPhones and Android devices. But they’re all programs.”
FAITH LAPIDUS: Apps are programs -- a series of instructions or orders for computing devices. When computers only sat in offices, applications were just another word for software programs. But with wireless devices, something changed. Now, you have computing power anywhere you go.
BOB DOUGHTY: Marc Buchner says the way people get apps is also different from earlier methods of getting software. Traditionally, software came on plastic CDs. It also could be downloaded on computers. But the payment process takes time and generally requires a keyboard.
