New Technology Lecture L12 The Rise of the Machine

Did you know that the term "Computer" once meant a profession? And what did people or computers actually do? They computed mathematical problems. Some problems were tedious and error prone. And it is not surprising that people started to develop machines to aid in the effort. The first mechanical computers were actually created to get rid of errors in human computation. Then came tabulating machines and cash registers. It was not until telephone companies were well established that computing machines became practical.

First computers were huge mainframes, but soon minicomputers like DEC’s PDP started to appear. The transistor was introduced in 1947, but its usefulness was not truly realized until in 1958 when the integrated circuit was invented. This led to the invention of the microprocessor. Intel, in 1971, marketed the 4004 – and the personal computer revolution started. One of the first Personal Computers was MITS’ Altair. This was a simple device and soon others saw the opportunities.

In this lecture we start our coverage of computing and look at some of the early machines and the impact they had.

  5. 5. 37 years ago “There  is  no  reason  for  any  individual  to  have  a   computer  in  their  home.”   -­‐  Kenneth  Olsen,  president  and  founder  of  Digital   Equipment  Corp.,  1977  
  6. 6. Think about this How many computers do you have in your household?
  7. 7. History Computing is time consuming and error prone ! Demands for computation were increasing with more organised societies ! Industrial revolution and the Napoleonic reforms ! ! Impetus came from Government: Taxing and Defence
  8. 8. The Counting Business Efforts to speed calculations started early ! Use of logarithmic tables and trigonometry to speed calculations
  9. 9. The Counting Business The Slide Rule by William Oughtred in 1625 ! Built using logarithms, multiplication of two numbers could be done easier a*b = 10^(log(a)+log(b)) ! ! ! ! Much quicker than manual calculation
