History of Early Computing Devices

What was one of the main reasons for the increasing need for automation and computation in the early 20th century?

• The invention of the telephone

• The decline in global trade

• The rapid increase in world population

• The discovery of electricity

What was a significant limitation of the Harvard Mark I?

• It had slow switching speeds and mechanical wear and tear

• It was too small to handle large calculations

• It was not programmable

• It could only perform one operation at a time

What was the primary component used in the Harvard Mark I to control circuits?

• Vacuum tubes

• Transistors

• Relays

• Diodes

Who developed the first vacuum tube, and what was it called?
