Who invented the first modern type of mechanical computing machine?
Correct Answer
D. Charles Babbage
Explanation
Charles Babbage is credited with inventing the first modern type of mechanical computing machine. He designed and conceptualized the Analytical Engine, a general-purpose computer that was programmable using punched cards. Although the Analytical Engine was never built during Babbage's lifetime, his work laid the foundation for modern computing. Babbage's contributions to the field of computing, including his ideas on algorithms and mechanical computation, make him a key figure in the history of computer science.
2.
What was the name of his invention?
Correct Answer
B. The Difference Engine
Explanation
The correct answer is "The Difference Engine." The Difference Engine was an early mechanical computer designed by Charles Babbage in the 19th century. It was intended to perform complex mathematical calculations automatically, eliminating the need for manual computation. Babbage's invention laid the foundation for modern computers and is considered a significant milestone in the history of computing.
3.
What method was used to feed instructions into early computing machines?
Correct Answer
C. Punch Cards
Explanation
Punch cards were used to feed instructions into early computing machines. These cards contained holes that represented binary code, allowing the machine to read and execute the instructions. The holes in the punch cards were created by a machine called a keypunch, which operators used to input the instructions. The cards were then fed into the machine, and the instructions were processed accordingly. This method was widely used before the development of more advanced input methods like keyboards and magnetic tape.

Which female was known as the "World's First Programmer"?
Correct Answer
C. Ada Augusta
Explanation
Ada Augusta is known as the "World's First Programmer" because she was a mathematician and writer who is credited with writing the first algorithm intended to be processed by a machine. She worked with Charles Babbage on his Analytical Engine, a mechanical general-purpose computer, and her algorithm was designed to be executed by this machine. This makes her the first person to recognize that a machine could be programmed to perform a series of calculations, making her the world's first programmer.

What was the first activity in America that spawned the need for a fast calculating machine?
Correct Answer
C. The American Census
Explanation
The American Census was the first activity in America that spawned the need for a fast calculating machine. Conducting a census involves collecting and analyzing a vast amount of data, which requires efficient and accurate calculations. As the population grew, the manual calculation methods became increasingly time-consuming and prone to errors. Therefore, the American Census created the demand for a fast calculating machine to streamline the process and ensure accurate results.
6.
Herman Hollerith invented the first tabulating machine that used Punch Cards.
What was the name of his company that sold machines to the American Census?
Correct Answer
B. Tabulating Machine Company
Explanation
Herman Hollerith's company that sold machines to the American Census was called the Tabulating Machine Company.
7.
This man, known for excellent sales skills eventually took over Hollerith's Tabulating Machine Company and later changed the name to International Business Machines (IBM).
Correct Answer
C. Thomas Watson
Explanation
Thomas Watson is the correct answer because he is the person who took over Hollerith's Tabulating Machine Company and changed its name to International Business Machines (IBM). This indicates that he had excellent sales skills as he was able to expand and rebrand the company successfully. Kent Brockman, Bill Gates, and John Mockley are not relevant to the given information and do not have any connection to IBM.

What was the name of the British computer that cracked the German codes during World War II?
Correct Answer
D. Colossus
Explanation
Colossus was the name of the British computer that played a crucial role in cracking the German codes during World War II. It was specifically designed to decipher the Lorenz cipher used by the German High Command. Colossus was a groundbreaking machine that used vacuum tubes to perform complex calculations at a much faster speed than previous technology. Its success in breaking the German codes greatly aided the Allies in their war efforts and is considered a significant milestone in the development of modern computers.
