Who is widely regarded as the 'Father of the Computer' for designing the first automatic mechanical calculator?
Correct Answer: B. Charles Babbage
Charles Babbage designed the Difference Engine and the Analytical Engine in the 19th century. Although they were never fully built during his time, they provided the fundamental architecture for modern computers. He is credited with the concept of a programmable computer.
Which pioneer is considered the world's first computer programmer for her work on the Analytical Engine?
Correct Answer: C. Ada Lovelace
Ada Lovelace wrote the first algorithm intended to be carried out by a machine. She realized that the Analytical Engine could go beyond simple calculations to handle complex symbols. Her notes included a method for calculating Bernoulli numbers using the machine.
Who is known as the 'Father of Modern Computing' and played a key role in cracking the Enigma code?
Correct Answer: B. Alan Turing
Alan Turing formulated the concept of a 'Universal Turing Machine' which could perform any computation. He provided the theoretical foundation for artificial intelligence and computer algorithms. His work during World War II at Bletchley Park saved millions of lives.
The first electronic general-purpose digital computer, ENIAC, was primarily designed by which duo?
Correct Answer: C. Mauchly and Eckert
John Mauchly and J. Presper Eckert developed ENIAC at the University of Pennsylvania in 1945. It was a massive machine that used vacuum tubes to perform thousands of additions per second. This invention marked the beginning of the electronic era in computing.
Who proposed the 'Stored Program' architecture that most modern computers use today?
Correct Answer: B. John von Neumann
John von Neumann described a computer design where data and programs are stored in the same memory space. This 'Von Neumann Architecture' eliminated the need to manually re-wire machines for different tasks. It is the standard framework for almost all general-purpose processors.
Which computer pioneer is credited with the invention of the first compiler and the term 'debugging'?
Correct Answer: C. Grace Hopper
Grace Hopper developed the A-0 System, the first compiler, which translated mathematical code into machine language. She was a Rear Admiral in the US Navy and led the development of the COBOL programming language. The term 'debugging' became famous after she found a literal moth in a relay.
Who is the inventor of the first computer mouse, which was made of wood?
Correct Answer: B. Douglas Engelbart
Douglas Engelbart invented the mouse in 1964 as a tool to improve human-computer interaction. He demonstrated it during the 'Mother of All Demos' in 1968 along with hypertext and windows. This device eventually became the standard input method for personal computers.
Which pioneer developed the first portable computer, the Osborne 1, in 1981?
Correct Answer: C. Adam Osborne
Adam Osborne founded Osborne Computer Corporation and launched the first commercially successful portable computer. Although it weighed 24 pounds and had a small 5-inch screen, it was a breakthrough in mobility. This invention paved the way for the modern laptop industry.
Who co-founded Microsoft and is considered a pioneer in the software industry?
Correct Answer: C. Bill Gates
Bill Gates co-founded Microsoft with Paul Allen in 1975 to develop software for early personal computers. Their success with MS-DOS and Windows made software a dominant force in global technology. He played a major role in making computers accessible to ordinary households.
Which inventor created the 'Difference Engine' in the 1820s to solve mathematical tables?
Correct Answer: B. Charles Babbage
Charles Babbage started building the Difference Engine to eliminate human errors in navigation and astronomy tables. It used the method of divided differences to perform calculations automatically. This was the first serious attempt at creating a complex computing machine.
