Across
- 5. German polymath active as a mathematician, philosopher, scientist and diplomat who invented calculus in addition to many other branches of mathematics, such as binary arithmetic
- 7. Known as the Father of the modern computer (even though none of his computers worked or were even constructed in their entirety)
- 11. He helped establish modern symbolic logic and whose algebra of logic, now called Boolean algebra, is basic to the design of digital computer circuits.
- 12. physicist and engineer, co-inventor in 1946, with John P. Eckert, of the Electronic Numerical Integrator and Computer (ENIAC), the first general-purpose electronic computer.
- 13. best known known for his work in the early development of computers: As director of the Electronic Computer Project at Princeton's Institute for Advanced Study (1945-1955), he developed MANIAC (mathematical analyzer, numerical integrator and computer)
- 15. completes Speedcode for IBM´s first large-scale scientific computer, the IBM 701. Although using Speedcode demanded a significant amount of scarce memory, it greatly reduced the time required to write a program. In 1957, Backus became project leader of the IBM FORTRAN project, which became the most popular scientific programming language in history and is still in use today
- 16. MS-DOS, or Microsoft Disk Operating System, the basic software for the newly released IBM PC, is the start of a long partnership between IBM and Microsoft, which he and Paul Allen had founded only six years earlier.
- 18. Named after her last name , first developed in 1801, is programmable. This loom used a series of punched cards to control the lifting of each individual warp thread to weave a figured fabric
- 19. was a pioneer in early digital computer development and invented random-access, coincident-current magnetic storage, which became the standard memory device for digital computers
Down
- 1. From Harvard ,finished the construction of the Automatic Sequence Controlled Calculator, popularly known as the Mark I. It contained over 3000 mechanical relays and was the first electro-mechanical computer capable of making logical decisions, like if x==3 then do this not like If its raining outside I need to carry an umbrella
- 2. The first all electronic computer was the Electrical Numerical Integrator and Calculator, known as ENIAC. It was designed by him and John W. Mauchly of the Moore School of Engineering at the University of Pennsylvania. ENIAC was the first multi-purpose electronic computer, though very difficult to re-program. It was primarily used for computer aircraft courses, shell trajectories, and to break codes during World War II.
- 3. Italian mathematician translated Luigi Menabrea's memoir on Charles Babbage's Analytic Engine. With her translation she appended a set of notes which specified in complete detail a method for calculating Bernoulli numbers with the Engine
- 4. American statistician, inventor, and businessman who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting.
- 6. an American businessman, engineer, and the co-founder and emeritus chairman of Intel Corporation. He proposed Moore's law which makes the observation that the number of transistors in an integrated circuit doubles about every two years
- 8. American electrical engineer who took part, along with Robert Noyce of Fairchild Semiconductor, in the realization of the first integrated circuit while working at Texas Instruments in 1958. He was awarded the Nobel Prize in Physics on 10 December 2000
- 9. She was a mathematician , that completed A-0, a program that allows a computer user to use English-like words instead of numbers to give the computer instructions. It possessed several features of a modern-day compiler and was written for the UNIVAC I computer, the first commercial business computer system in the United States.
- 10. This mathematical genius, at the age of 19 invented a machine, which he called the “ Pascaline” that could do addition and subtraction to help his father.
- 14. Him and his graduate assistant, Clifford Barry, built the first truly electronic computer, called the Atanasoff-Berry Computer or ABC
- 17. He was especially interested in devising ways to aid computations. His greatest contribution was the invention of logarithms. He inscribed logarithmic measurements on a set of 10 wooden rods and thus was able to do multiplication and division by matching up numbers on the rods
