In a time of budget cuts and limited funding, purchasing and installing the latest software on classroom computers can be prohibitive for schools. Many educators are unaware that a variety of free software options exist, and some of them do not actually require installing software on the user's computer. One such option is cloud computing. This popular technology trend has been gaining momentum over the last 4 years. Cloud computing is a computing technology that uses the Internet and central remote servers to maintain data and applications. Cloud computing allows students and teachers to use applications without installing them on their computers and also allows access to saved files from any computer with an Internet connection. This technology involves much more efficient computing by centralizing storage, memory, processing, and bandwidth. It also enables a number of individuals to simultaneously work on a project--regardless of their location. The term cloud computing is used because the services and storage are provided over the Internet (or cloud). This article discusses examples of cloud computing offerings and the four major advantages to cloud computing. (Contains 5 figures.)
