THE EARLY DAYS (1,000 B.C. TO 1940)
Computers are named so because they make mathematical computations at fast speeds. As a result, the history of computing goes back at least 3,000 years ago, when ancient civilizations were making great strides in arithmetic and mathematics. The Greeks, Egyptians, Babylonians, Indians, Chinese, and Persians were all interested in logic and numerical computation. The Greeks focused on geometry and rationality, the Egyptians on simple addition and subtraction, the Babylonians on multiplication and division, Indians on the base-10 decimal numbering system and concept of zero, the Chinese on trigonometry, and the Persians on algorithmic problem solving.
These developments
carried over into the more modern centuries, fueling advancements in areas like
astronomy, chemistry, and medicine.
