Document Summary
Very small changes to control grid --> large change in electron flow btwn anode and cathode. In other words, a weak signal on grid is amplified. Very large neg charge on grid --> electron flow btwn anode and cathode stops. X modules with vacuum tubes large & generated a lot of heat. = solid-state triode, made of silicon/germanium + doped using phosphor. 1 bit = 1 binary digit (aka 0/1) 1 word = a fixed-width collection of bits. Usually all ops in a cpu use same word size. A word of size n bits can represent: Numbers from 0 (all 0s) to 2n-1 (all 1s) To rep decimal number x, need log2(x) bits. Used for computation bcos easier to design elec circuits that work w/ 2 symbols. ** when keeping track (indexes), index 0 on right, highest on left. Used as simplification of binary, esp if binary is too long and too many.
