The evolution of computers progressed through three main ages - the Dark Age, Middle Age, and Modern Age. In the Dark Age, early mechanical devices like the abacus and slide rule were developed to assist with calculations. During the Middle Age, pioneers like Charles Babbage and Herman Hollerith developed early mechanical computers that could perform basic arithmetic. This led to the creation of IBM. In the Modern Age, electronic digital computers were invented, like the MARK I and ENIAC, marking the beginning of programmable computers.

- 1. Evolution of Computers Introduction: The evolution of Computer as come through different ages before it as reached to the present day computers. The origin of the development of the computer was more than 3000 years ago. The different ages in the development of computers are, Dark age Middle age Modern age Dark Age During this age, a few devices were developed. They are classified into two namely, Semi-mechanical and Mechanical devices. SEMI – MECHANICAL DEVICES These devices needed manual help to get utilized. Some of the Semi-mechanical devices are Abacus (Chinese and Japanese), Napier’s bones, Slide Rule. 3000 B.C. / Abacus Abacus is the ancient counting device mainly used for doing addition and Subtraction.
- 2. 1614 / Napier’s Bones John Napier developed Napier’s Bones for doing multiplication. 1632 / Slider Rule William Oughtred, an English mathematician developed Slide Rule. Slide Rule was extensively used for engineering calculations. William also invented the ( X ) sign for multiplication. Mechanical Devices Mechanical devices are those, which reduces manual work some of the mechanical devices are Pascaline, Tooted Wheel.
- 3. 1642 / Pascaline A French mathematician and an experimental physicist, Blaise Pascal developed an adding machine called Pascaline. 1673 / Toothed Wheel This was the first machine that could solve problem based on basic Arithmetic Operations ( +, -, x, ).
- 4. Middle Age The Scientists of te middle age concluded tat all te computing devices must have three basic principles, the input, The process and the output. Some of the middle age computing devices are Analytical Engine, Hollerith tabulator Analytical Engine Charles Babbage, Professor of mathematics at Cambridge University devised this machine which has four Components the input unit, mill, the store and the output unit.
- 5. Lady Augusta Ada Lovelace Lady Augusta Ada Lovelace was the first lady programmer who helped Charles Babbage in writing programs for his machine. Hollerith’s Tabulator Hollerith developed a technique for processing the data. He develop[ed punched card (Statistical tabulator) where the data were in the form of tiny holes. These punched card were read by the Tabulating machine . Herman Hollerith formed his own company in the year 1896 and named I as “The Computing Tabulating Recording Company”. Later on they renamed e company as International Business Machine (IBM).
- 6. Modern Age In 1930’s the scientist wanted to develop a machine that could perform something more than just calculations (logically). They wanted it to work electrically and not mechanically. Some of these computers are MARK I ENIAC MARK I The first automatic machine MARK I was developed by Howard Aikens.This machine was mainly used by the military during World War II, to calculate the speed of missiles. ENIAC Electronic Numerical Integrator and Calculator was the first electronic digital computer designed by John Mauchly and Prosper Eckert during World War II.
