ENIAC, the first computer capable of general problem solving, consisted of 70,000 resistors, 17,468 vacuum tubes, 10,000 capacitors, 7,200 crystal diodes, 1,500 relays, and around 5 million hand-soldered joints. At 27 tons, it filled an entire room, consumed 150 kW of power and required six people to program its routines. Today, a chip of silicon the size of a grain of sand has the same computing power as ENIAC. ENIAC went into operation in 1946. In the past sixty years more and more jobs have been transformed until now almost every mode of employment involves complex information processing in some way shape or form. Continue reading →
