Computer science (CS) is the study of computers, including their mathematical properties, design, operation, and use in processing information. CS combines theoretical and practical aspects of engineering, electronics, information theory, mathematics, logic, and human behavior. Modern computer science consists of many diverse fields, from programming and computer architecture to artificial intelligence and robotics.

The roots of computer science are indistinguishable from engineering and mathematics. In the seventeenth and eighteenth centuries, men such as French mathematician Blaise Pascal (1623-1662) and German mathematician Gottfried Leibniz (1646-1716) created small mechanical devices for adding and multiplying numbers. The first computer, in any recognizable sense of the word, was probably the analytical engine conceived by English mathematician and engineer Charles Babbage (1791-1871) around 1835. Though never completed by Babbage, his analytical engine was to have many attributes that would be used by various computers of the twentieth century...
