Use a search engine such as Google to find information about Gordon E. Moore and Moore’s law, the famous law about technological advances that he proposed. (a) What is Moore’s law? Give a brief description in your own words. (b) Who is Gordon E. Moore? What was his position at the time he first proposed Moore’s law? What company did he later cofound? With whom did he cofound this company? (c) In what field did Gordon E. Moore obtain his BS degree? At what university did he receive his BS degree? Where did he obtain his PhD degree? In what field was his PhD degree? (d) What Nobel Prize-winning physicist gave Gordon E. Moore his first job opportunity? (e) What was the number of the first microprocessor developed at Moore’s company and how many transistors did it have! When was it introduced! (f) Read the article by Thomas Friedman on Moore’s law, and watch the video of his interview of Gordon E. Moore.9 In what year in what publication did Moore make his prediction? What was the most important lesson that Moore learned from his law? What stimulated his interest in science and engineering? What does Moore see as the biggest problem in science? How would you describe thestatus of Moore’s Law today! (g) One important benchmark ofcomputational progress is the performance-to-price ratio (PPR) of computers.10 The PPR is the number of bits per word divided by the product of cycle time (1/clockspeed) and price. The original IBM PC (1981) with an 8bit word length, a 4.77 MHz clock, and a pricetag of $5000 came in with a PPR of ~7600. Computers based on other processors available in 2000 are listed in the following table.10 Calculate the PPR of each of these computers. Does Moore’s law hold forthe PPR? How did you come to your conclusion?
