Business computing

Mobile platform: More and more business computing is moving from PCs and desktop machines to mobile devices like cell phones and smartphones. Data transmissions, Web surfing, email and instant messaging, digital content displays, and data exchanges with internal corporate systems are all available through a mobile digital platform. Netbooks, small low-cost lightweight subnotebooks that are optimized for wireless communication and Internet access, are included. The mobile platform is expanding to include tablet computers (iPad) and digital e-book readers.

Grid computing: Connects geographically remote computers into a single network to create a “virtual supercomputer” by combining the computational power of all computers on the grid. Since most computers use their central processing units only about 25 percent of the time, they can be used for other tasks.

Cloud computing: A model of computing where firms and individuals obtain computing capacity, data storage, and software applications over the Internet, rather than purchasing their own hardware and software. Data are stored on powerful servers in massive data centers, and can be accessed by anyone with an Internet connection and standard Web browser. Public clouds are maintained by external service providers while private clouds are restrained inside a proprietary network or a data center.
