Which item is an online communication?

• A. Distributed computing
• B. Open databases
• C. Crowdsourcing
• D. Email

Answer: (D)

Online communication is about exchanging messages or information through the internet. Email fits this because it is a service that lets people write messages, attach files, and send them to others over a network. Messages move between mail servers, enabling communication across different devices and times, which is the essence of online communication. The other items describe different concepts: distributed computing involves multiple computers working together on tasks; open databases are publicly accessible data stores; crowdsourcing gathers contributions from many people, often for ideas or content rather than direct messaging. Because email is specifically designed for delivering messages between people over the internet, it is the online communication option.
