Computer Science Overview Quiz

Computer Science

Computer science is a discipline of applied mathematics concerned with the theory, experimentation, and engineering design of computation. It encompasses algorithms, complex systems, computer hardware and software, databases, digital government, information security, programming languages, artificial intelligence, human-centered computing, theory, and more.

History of Computer Science

The history of computer science can be traced from its origins in counting, calculation, and abacus use up through modern technologies such as quantum computers. Early developments in logic and algebra laid the groundwork for later advances in computer technology. Charles Xavier Thomas de Colmar built the first electrically operated calculating machine, called the 'Pascaline'. In 1879, Thaddeus S. Cahill constructed the first automatic adding machine, known as the "Difference Engine No. 1," using vacuum tubes. Herman Hollerith invented the electric tabulator, which was used by the U.S. Census Bureau in 1890, greatly speeding up data processing operations.
