Possibly the abacus, a board with wood rods, and wood beads on the rods. It is thousands of years old.
The first electronic computer, I think, was Univac. It used vacuum tubes instead of solid state devices to do its computing.
Electronic computers in the sense that we know them today did not exist in the early 1940s. When the first digital machines were developed near the end of WW2 they were either very specialized calculating machines and so did not have a "typical" configuration, or were enormous, room-sized devices weighing many thousands of pounds.
yes indeed young sir!
The earliest recorded calculating device is the abacus. Used as a simple computing device for performing arithmetic, the abacus most likely appeared first in Babylonia (now Iraq) over 5000 years ago.
