FC: History Of Computers

1: In 1642, in an effort to ease his father's endless, exhausting calculations, and recalculations, of taxes owed and paid, Pascal, not yet 19, constructed a mechanical calculator capable of addition and subtraction, called Pascal's calculator or the Pascaline.

2: In 1800, Joseph began to dabble in inventing: a treadle loom in 1800, a loom to weave fishing nets in 1803, and starting in 1804, the “Jacquard” loom, which would weave patterned silk automatically.

3: The first bombe was installed on March 18, 1940 and was used for possible correct settings used for an Enigma message using a suitable crib. For each possible setting of the rotors the bombe performed a chain of logical deductions based on the crib, implemented electrically. The bombe detected when a contradiction had occurred, and ruled out that setting, moving on to the next. Most of the possible settings would cause contradictions and be discarded, leaving only a few to be investigated in detail.

4: ENIAC was the first electronic general-purpose computer. It was Turing-complete, digital, and capable of being reprogrammed to solve a full range of computing problems.

5: ENIAC was designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory.When ENIAC was announced in 1946 it was heralded in the press as a "Giant Brain". It had a speed of one thousand times that of electro-mechanical machines, which was unmatched by mechanical computers. This mathematical power, coupled with general-purpose programmability, excited scientists and industrialists.

6: UNIVAC is the name of a line of electronic digital stored-program computers starting with the products of the Eckert-Mauchly Computer Corporation

7: Don't think: Look! -Ludwig Wittgenstein | The original model was the UNIVAC I (UNIVersal Automatic Computer I), the second commercial computer made in the United States. The main memory consisted of tanks of liquid mercury implementing delay line memory, arranged in 1000 words of 12 alphanumeric characters each. The first machine was delivered on March 31, 1951.

8: Mainframe computers (referred to as "big iron") are computers used primarily by corporate and governmental organizations for critical applications, bulk data processing such as census, industry and consumer statistics, enterprise resource planning, and transaction processing. The term originally referred to the large cabinets that housed the central processing unit and main memory of early computers.Later, the term was used to distinguish high-end commercial machines from less powerful units.Most large-scale computer system architectures were established in the 1960s, but continue to evolve.

10: Computers have came a long way and are still evolving. They now are extremely advanced, compared to how they were a few years ago and are becoming more advanced with time.
