The world's first "automatic electronic digital computer" was the Atanasoff-Berry Computer, conceived and built by Atanasoff and Berry during 1937-42, but the invention was "reduced to practice" no later than 1939. The ENIAC invention was later derived from this work, thus invalidating the ENIAC patent, and the British Colossus computer was not invented until 1944.
Some believe incorrectly that the abacus is a "computer", and it was invented a very long time ago. However, others believe that the abacus was no more a "computer" than, say, a dictionary in a book is a spell checker; it is a tool manipulated by humans in a way that results in an answer.
Charles Babbage invented his Counting Machine which is considered to be the first computer in modern terminology.
Originally, the term 'computer' was used (in some contexts into the mid-20th century) for a person who computed numbers or a clerk.

No, the first electronic digital computer was made in 1942. Its invention was about 1937.Electronic digital computers have been manufactured for sale since 1950.

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 electronic computer was not invented in 1641, there was no electronics in 1641. The electronic computer was invented in the 1940s. Charles Babbage did invent the programmable digital computer, the Analytical Engine, but it was mechanical not electronic.
