Study advice (same as Test 1) 

Course Material  TEST 1 MATERIAL History of Computers generation 0: mechanical (Jacquard's loom, Babbage & Lovelace, relay machines) generation 1: vacuum tube (COLOSSUS, ENIAC, von Neumann architecture) generation 2: transistor (miniaturization & mass production, highlevel languages) generation 3: integrated circuit (mass production of complex circuitry, OS) generation 4: microprocessor (massproduced calculators, Moore's Law, PC revolution) generation 5: ultra largescale integration (networking, mobile, AI) Scientific & Computational Thinking history of science Greek prescience, Islamic empire, Dark Ages, Renaissance, Scientific Revolution scientific method: observe, hypothesize, design, experiment, analyze experimentation, reproducability, consistency vs. accuracy computational thinking decomposition, pattern matching, abstraction, algorithms examples: algorithms for finding oldest person (simple vs. efficient) Algorithms & Programming realworld algorithms algorithm analysis, rate of growth, Big Oh notation examples: sequential search vs. binary search, Newton's algorithm machine language vs. highlevel language program translation: interpreter vs. compiler Computer Science as a Discipline study of computation, artificial vs. natural science CS themes: hardware, software, theory subfields of CS Algorithms & Data Structures: publickey encryption Architecture: parallel processing, multicores Operating Systems & Networks: Ethernet, WiFi Artificial Intelligence: Turing Test, neural networks multidisciplinary fields Bioinformatics, Data Science ethics of computing Experimental Methods Monte Carlo methods, simulations/modeling, Law of Large Numbers Applications in Biology major impacts: computerized tools, modeling, information storage/retrieval Interaction & Design text boxes input tag; id and style="text" attributes, optional size & value attributes examples: greetings, form letter, fillintheblank story userdefined functions used to simplify the body, move action code to the head (in a script element) function definition: function func_name() { ... } function call: func_name(); examples: form letter, animal gallery, quotations design guidelines Numbers & Computation JavaScript data types: strings, numbers, Booleans numbers & expressions mathematical operators (+, , *, /) number box, valueAsNumber attribute variables to store number values and temporary calculations examples: tip calculator, grade calculator predefined functions Math.sqrt, Math.abs, Math.floor, Math.ceil, Math.round Math.min, Math.max, Math.pow examples: point distance, compound interest random numbers Math.random, complex expressions to adjust range of values example: pick4 lottery Functions & Libraries can view functions as units of computational abstraction userdefined functions parameters, return statement common use: for generalpurpose computations examples: distance conversion, simplified pick4, triangle sides function libraries SCRIPT tag with SRC attribute to specify library file name common use: for collections of functions that may be reused random.js library RandomNum, RandomInt, RandomChar, RandomOneOf library functions examples: dice, random sequence generator, Oracle of Internet
