Week 1 9/3	Tuesday Syllabus Introduction to the class and the 1/2 semester schedule Organization of the class a short movie to get the discussion started... some examples of computers: Antikythera mechanism, oldest computer (start at 1min 47sec) Harvard research: 1.8 zettabytes in 4 grams of DNA Keywords: code: Translating from one system of values to another system. Electricity The Binary System: a system where the only two numbers available are 0 and 1. Every operation that we can do in decimal, with 10 digits, we can also do in binary. The Transistor: A switch controlled by electricity. Counting in binary Thursday Announcement: If you want to take CSC102 and haven't contacted Pippin Wolfe (apwolfe@smith.edu), please do so now! Quick recap of Tuesday's lecture. A movie on Babbage's Difference Engine We continue counting in binary, then move on to simple additions in binary, remembering first how we do additions by hand in decimal. Figuring out the value of a binary number: what is the value of 1110, for example? ==> Main message: everything we can do in decimal we can do in binary Recap: at some point in time, engineers had very fast electronic switches at their disposition in the form of transistors mathematicians had shown that a binary system allowed the same quality of arithmetic as the decimal system. Comes Boole (1815-1864), and the boolean algebra (very soon we'll talk about Shannon, who linked Boole's work with binary arithmetic. More on that later) Boolean assertions can be either True or False new boolean assertions can be combined with simple operators to form other assertions that are also boolean and can only be True or False The operators are AND, OR, and NOT. They are defined by truth tables. Several examples to discuss in class: Alarm system to go to CSC103 the right day at the right time Alarm system to allow one to stay in bed during the weekend True/False machine to pick ice cream	Reading Primary: Video (Part 2) on George Boole and Boolean Algebra. (5.18 min) Shannon's MIT Thesis, and boolean theory Counting in Binary Secondary: Instructor's Notes (read only the beginning part)
Week 2 9/10	Tuesday Review of where we are Binary system Boolean variables, boolean operators, and boolean functions The "ice cream machine" example From boolean function to truth table From truth table to boolean function Shannon's thesis (1948): we can do arithmetic with logic! Look at the binary addition as an operation in the world of logic Logic gates: the AND gate, the OR gate, and the NOT gate (also called inverter). building a 2-bit adder with logic gates. Electronic circuit: Logic Gates Data sheet for the AND gate. Data sheet for the NOT gate. Data sheet for the OR gate. Thursday Lab (you may want to bring your laptop if you prefer to work on your laptop rather than the iMacs) The lab is available here. Homework 1 due 9/17/13 at 9:00 a.m. Lab 1 to be done in class on 9/12/13. lab solution.	Reading: Instructor's Notes Logic Gates on wikipedia: You can skip the Universal Logic Gate section, the De Morgan section, and the remaining sections until the end.
Week 3 9/17	Tuesday Schematics from NASA Exercises to do in class From logic gates to flip-flops: the magic Let's play a game! The xComputer Simulator Programming in Assembly Language Basic Instruction Set Thursday The Cookie Monster! Assembly Language the xComputer Simulator the Instruction Set for our computer A first program A second program Execution of selected instructions (pdf) Exercises Lab on Assembly Language Homework 2 due 9/24/13 at 9:00 a.m.	Reading: von Neumann's bottleneck A good description of the Computer simulator You will find Wikipedia's description of the processor interesting. Concentrate mostly on the sections labeled Microprocessor, Operation, and Clock Rate.
