The educated man of 200 years ago did not need to know anything about science. The educated man of 25 — 30 years ago did not need to know anything about computers. But the educated man of today needs to have some significant knowledge of science and a little significant knowledge about computers. The computer is no doubt the most amazing achievement of mankind. It is a date storage system created by man. A human tells the machine what to do, when to do it and how it should be done. The word computer comes from a Latin word which means to count. In 1833 an English inventor and mathematician Charles Babbage, professor of Cambridge University designed the first computer. The mathematical programme for his machine had been composed by Lord Byron's daughter. The first programmer computer which operated successfully was built tin 1939 by H H. Aiken, professor of Harvard University. In our country the first electronic digital computer MACM was constructed by the Ukrainian Academician S. O. Lebedev in 1950.Such computers as BESM, Minsk, Ural, Razdan-3, M-20, M-220, Nairi-3, Strela, Dnepr were created in our country. Nowadays computers greatly increase man's thinking capabilities of planning, analyzing, computing and controlling. Hundreds of computers are already in daily use. They penetrate almost into all spheres of our modern society.
