The SETI (Search for Extraterrestrial Intelligence) project collected vast amounts of data that needed processing. SETI was one of the early adopters of a technology in which volunteers installed a small application on personal computers to receive, process and return information to SETI. Using multiple systems to process large amounts of data was considered to be less expensive than using a single supercomputer to conduct the same task. This technology is typically known as:
answer choices
collective intelligence.

Software as a Service.

crowdsourcing.

grid computing.

Based on the information provided within the question it can be said that this technology is typically known as grid computing. Like mentioned in the question, this is a type of processor architecture in which various computer resources are combines from different domains in order to work together towards a common main objective. Which is exactly what SETI has done by using many individual's computers to essentially create one supercomputer capable of handling all the data.
