Computer - Technology, Invention, History: By the second decade of the 19th century, a number of ideas necessary for the invention of the computer were in the air. First, the potential benefits to science and industry of being able to automate routine calculations were appreciated, as they had not been a century earlier. Specific methods to make automated calculation more practical, such as ...
Computer science is the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information. The discipline of computer science includes the study of algorithms and data structures and artificial intelligence.
Alan Turing was a British mathematician and logician, a major contributor to mathematics, cryptanalysis, computer science, and artificial intelligence. He invented the universal Turing machine, an abstract computing machine that encapsulates the fundamental logical principles of the digital computer.
Computer science - Algorithms, Complexity, Programming: An algorithm is a specific procedure for solving a well-defined computational problem. The development and analysis of algorithms is fundamental to all aspects of computer science: artificial intelligence, databases, graphics, networking, operating systems, security, and so on.
A computer is a programmable device for processing, storing, and displaying information. Learn more in this article about modern digital electronic computers and their design, constituent parts, and applications as well as about the history of computing.
Computer - History, Technology, Innovation: How did the abacus lead to modern computers? The earliest known calculating device is the abacus, dating back to at least 1100 BCE and still in use today, particularly in Asia. The abacus showed that calculations could be represented physically and manipulated systematically. Its use of discrete bead positions—on or off—anticipated the digital ...
