2. Charles Babbage
3. Gottfried Wilhelm Von Leibniz
4. Thomas John Watson, Jr.
5. Konrad Zuse

2. Who first used binary numbers instead of decimal numbers in the development of computers, the Z series of computers?

1. Augusta Ada Byron, Countess of Lovelace
2. Charles Babbage
3. Gottfried Wilhelm Von Leibniz
4. Thomas John Watson, Jr.
5. Konrad Zuse

3. What apparatus was built by George Stibitz, in the 1940s in the USA, that affected the designs of computers that were developed after this invention?

1. Analytical engine
2. Automated weaving machine
3. Binary adder
4. Difference machine
5. Stepped reckoner
6. Tabulating machine

4. In the 1940s in the USA, John V. Atanasoff and Clifford Berry built the first machine that did arithmetic using vacuum tubes.

1. binary
2. decimal

5. Howard H Aiken developed and built the Mark 1 machine for calculating mathematical tables in 1943. Its major problem was that it was a machine.

1. electronic
2. mechanical

6. What was used to feed (input) data into Howard H Aiken’s Mark 1 machine?

1. keyboard
2. paper tape
3. transistors

7. In the USA in the 1940s, who developed the ENIAC (Electronic Numercial Integrator and Computer)?

1. Howard H Aiken
2. John V. Atanasoff and Clifford Berry
3. John W. Mauchly and J. Presper Eckert
4. Thomas J. Watson

8. What is it?

An electronic device used as a voltage and current amplifier, consisting of semiconductor materials that share common physical boundaries. The materials most commonly used are silicon and germanium into which impurities have been introduced. s are a key component of integrated circuits and are used in many applications, including radio receivers, electronic computers, and automatic control instrumentation (e.g., in spaceflight and guided missiles). Since the invention (announced in 1948) of the by the American physicists John Bardeen, Walter H. Brattain, and William Shockley, many types have been designed.

1. Punched card
2. Transistor
3. Vacuum tube

9. News report 1946

ENIAC (electronic numerical integrator and computer) is the world’s first automatic electronic digital computer and makes the Mark I electromechanical computer of 1944 obsolete. A massive device that employs 18,000 radio tubes and large amounts of electric power, operates on the principle that vacuum tubes can be turned on and off thousands of times faster than mechanical relays, and can make some 4,500 additions per second; although its tubes are not reliable and it functions only for brief periods, ENIAC begins a revolution in industrial technology. University of Pennsylvania electrical engineers John Presper Eckert, 27, and John William Mauchly, 39, have developed ENIAC following Mauchly’s visit with University of Iowa scientist John Vincent Atanasoff, now 41, who has invented basic concepts of computer technology.

What was developed first?

1. ENIAC
2. Mark 1

10. News report

Mark 1 - The first automatic, general-purpose digital computer is completed at Harvard University, where it has been built under the aegis of Engineering School mathematics professor Howard Hathaway Aiken, 44, with a $5 million grant from IBM. The Harvard-IBM Mark I Automatic Sequence Controlled Calculator has 760,000 parts and 500 miles of wire, requires 4 seconds to perform a simple multiplication, 11 seconds for a simple division, and is subject to frequent breakdown.

Who do you associate with IBM, the firm which provided the grant to develop the Mark 1?

1. Augusta Ada Byron, Countess of Lovelace
2. Charles Babbage
3. George Boole
4. Joseph-Marie Jacquard
5. Blaise Pascal
6. Gottfried Wilhelm Von Leibniz
7. Thomas John Watson
