Explanation

Cloud computing is defined as an internet-based service model that provides shared resources, software, and information to computers and other devices on demand. This paradigm allows users to access computing power, storage, and applications over the internet without managing physical infrastructure. While the provided snippets discuss the rapid evolution of telecommunications, internet connectivity, and the digitization of information [3], they highlight how integrated networks have enabled instant information access and remote communication [2]. Option 1 describes wireless networking, Option 2 refers to general telecommunications like cellular access [4], and Option 3 describes Bluetooth technology. Cloud computing specifically leverages the 'amazing world of internet' [2] to deliver scalable, on-demand services, distinguishing it from the hardware-centric or local wireless connectivity descriptions found in the other options.
