Document Summary
Systems that allow managers to record and store data, and to analyze and use data to obtain information and acquire knowledge. Allow humans to acquire knowledge ie. 1850- telegraph and the morse code allowed the transcontinental rail-lines and opened trans-continental markets. 1876- telephone allowed electronic transmission across the world. 1901- marconi transmits sound signals from ireland to canada. 200 ad china- abacus - mechanical device for the rapid computation of complex numerical data. The number of transistors that can be placed inexpensively on integrated circuit doubles every 2 years. Electronic computing: used vacuum tubes (not mechanical devices) to do its calculations. Large scaled and very large scale integrated circuits. Microprocessors that contained memory, logic, and control circuits on a single chip. Worldwide network of computers, linked together so that they can communicate with any other computer. Original developed in 70"s for us research scientists to communicate with each other.
