The document traces the history of computing from mainframes in the 1950s-1970s with reel-to-reel tape storage accessed through terminals, to midrange systems in the 1980s, servers in the late 1980s-1990s, server racks in 2000, and now lights out data centers known as the cloud, with the cloud powered by quantum computing using bits and qubits in quantum computers located in data centers like Google's.

10. Welcome to Quantum Mechanics!!!
Yes… this is the how the ‘magic works’
in ‘The Cloud’
