Explanations: answer key for all 10 questions

Q1: Which machine did Charles Babbage design as a general-purpose computer?
Answer: Analytical Engine
It was never completed but had memory and a processor in concept.
Q2: Colossus was built in 1943-44 to help break which codes?
Answer: German Lorenz codes
It was built at Bletchley Park by Tommy Flowers.
Q3: ENIAC, completed in 1945, used about how many vacuum tubes?
Answer: About 17,500
It filled a large room and weighed about 27 tonnes.
Q4: Which invention of 1947 replaced vacuum tubes?
Answer: Transistor
Bardeen, Brattain and Shockley won the Nobel Prize.
Q5: UNIVAC I famously predicted the result of which 1952 event?
Answer: US presidential election
It predicted Eisenhower's win.
Q6: Which computer pioneer helped popularize the word bug after a moth was found?
Answer: Grace Hopper
The moth was taped into a logbook in 1947.
Q7: Who co-invented the integrated circuit in 1958-59?
Answer: Jack Kilby and Robert Noyce
Kilby won the 2000 Nobel Prize.
Q8: What was the first commercial microprocessor, from 1971?
Answer: Intel 4004
It had about 2,300 transistors.
Q9: Which 1977 computers helped launch personal computing?
Answer: Apple II, Commodore PET and TRS-80
They were called the 1977 trinity.
Q10: Which German engineer built the Z3, an early programmable computer, in 1941?
Answer: Konrad Zuse
It used telephone relays.

Early Computers Quiz – From Gears to Chips

The idea of a programmable computer began with Charles Babbage's Analytical Engine in the 1830s, and Ada Lovelace wrote what is often called the first computer program. Their designs were far ahead of the technology of their time.

World War II pushed electronic computing forward. Colossus helped break German codes, Konrad Zuse built the Z3 and ENIAC calculated artillery tables. These machines filled rooms, used thousands of vacuum tubes and needed teams of operators.

The transistor, integrated circuit and microprocessor shrank computers dramatically. By the late 1970s, personal computers appeared in homes, and today a smartphone is millions of times more powerful than ENIAC.
