__________ is distributed computing over a network, and involves a large number of computers connected via real-time communication network such as the Internet.

Correct option is A

Cloud Computing refers to distributed computing over the internet, where data and applications are hosted on remote servers and accessed by users via the web. It involves a large network of servers and allows users to access data and resources remotely.
Important Key Points:
1. Resource Sharing: Cloud computing enables shared resources and storage over the internet.
2. Scalability: Cloud services are easily scalable, making it ideal for distributed computing.
3. Cost-Effective: Reduces hardware and maintenance costs by centralizing resources.
Knowledge Booster:
· Thin Client Computing: Refers to lightweight devices that rely on central servers for processing.
· Fat Client Computing: Involves clients with substantial processing power, usually requiring less reliance on central servers.
· Dumb Terminal Computing: Refers to terminals that provide input/output functions but rely entirely on a mainframe for processing.
