This is the fashionable new term for a networking system once more commonly called distributed computing. The basic idea is that instead of running a program on one big computer, you run it on a lot of quite small computers connected through a network. An example is the SETI@Home project, in which spare time on thousands of PCs is borrowed using the Internet to analyse data from radio-astronomy signals with the aim of finding evidence of extraterrestrial life. A similar kind of project searching for very large prime numbers has found five new ones. The idea is attractive to large companies, which often have thousands of idle networked PCs. Various computer companies, such as IBM, are working towards commercialising what has now been renamed grid computing and a centre to develop the idea was opened in Edinburgh in April. The term comes from the electricity grid that connects producers with consumers.
The idea behind distributed or grid computing is to share computer applications and resources, such as processing power and storage, over the Internet.

The grid computing concept enables us to use computing power and data storage as if they were some kind of utility like electricity, gas and water.
