• Crowdsourcing

• Grid computing

• Scalability

What is the main purpose of a file server?

Your company offers software applications for various topics. When a customer purchases a desired app from your online store, she is directed to a page where she can download the application directly. When the customer begins downloading the app, the standard protocol that is most likely transferring the application is:

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:

• collective intelligence.

• Software as a Service.

• crowdsourcing.

• grid computing.

Which protocol is used to host newsgroups and distribute mailing lists by providing text output that users can access and by allowing multi-person input?

What is the term for a software application that enables users to access and view Web pages on the Internet?

• Web browser

• Website

• Web form

• Web link

Which of the following describes cloud computing?
