Dr. WangLecture #130 Vacuum Tubes Vacuum tubes are glass tubes with circuits inside. Vacuum tubes have no air inside of them, which protects the circuitry. http://en.wikipedia.org/wiki/Vacuum_tube

Dr. WangLecture #132 ENIAC (Cont’d) A decimal machine (not binary) 5000 additions per second Data was entered on punched cards Entering & altering programs was extremely tedious –programmed manually by setting switches and plugging & unplugging cables –programming for typical calculations required from 1/2 hour to a whole day
33
Dr. WangLecture #133 Stored-Program Concept Proposed by Von Neumann in 1945 Developed by Turing about the same time Applied to IAS computer by Von Neumann et al. Programming could be facilitated if program could be represented in a form suitable for storing in memory alongside the data. Then a computer could get its instructions by reading from memory, and a program could be set or modified by setting the values of a portion of memory

Dr. WangLecture #142 Moore’s Law Number of transistors on a chip will double every year - by Gordon Moore, Intel cofounder in 1965 The pace slowed to a doubling every 18 months and sustained ever since 1970s (refer to Figure 2.8 in textbook)
43
Dr. WangLecture #143 Moore’s Law (Cont’d) How long will Moore's Law hold? –Moore (1997): It'll go for at least a few more generations of technology. Then, in about a decade, we're going to see a distinct slowing in the rate at which the doubling occurs. I haven't tried to estimate what the rate will be, but it might be half as fast - three years instead of eighteen months. –See class web-site (Lecture Reading) for details
