the first computer was created by CHARLES BABBAGE and it was known as the analog computer....
The Greeks are assumed to have invented the first known computer circa 100BC, a mechanical analog computer for astronomical calculations assumed to be used as a navigational aid on ships.
It was a greek philosopher just over 2000 years ago.
The first known analog computer is the antikythera mechanism. It was found underwater in 1900. It is believed to have been made prior to 100BC. Inventor unknown.
The first Indian analog computer was assembled in 1950
The Antikythera mechanism is believed to be the earliest known mechanical analog "computer" by Derek J. de Solla Price. It was designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to circa 100 BC. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later.
Analogue
it was an astronomical calculator. A form of mechanical analog computer. The nordon bombsight was also a form of mechanical analog computer.
ages ago
Uncertain, but sometime in the early 1950s when an off the shelf electronic analog computer was interfaced to an electronic digital computer.
Never, because it did not preexist its use by humans. The electronic computer (both digital & analog) was invented.
The first power supply was invented by Thomas Edison. It is unknown when exactly the first universal power supply for computers was invented.
