T. he . goal of logic is to develop formal tests for validity. This is done by finding deductively valid argument forms. In SL, we have two tests to determine valid argument forms: the truth-table test, and derivations. Any argument that has a form that is valid according to the truth-table test is valid, and any argument that has a form that can be proven is valid.. Class 9/15 - Video on Watson playing Jeopardy .

We already know that the language of the machine is . binary. – that is, sequences of 1’s and 0’s. But why is this? . At the hardware level, computers are streams of signals. These signals only have two states of interest, high voltage and low voltage. . Microchips (processors) . do exactly whatever instructions are fed into it, and that too without a single mistake.. Boolean . Logic was first introduced by George . Boole. The . basic . Boolean . operation can be further mapped into operations using bits and bytes. The most basic idea of Boolean Logic can be explained using logic gates. When the logic required becomes complex, these logic gates can be combined into more complex forms to get the required output. a & b. a | b -– true if a or b true or missing. a & b – true if a and b true or missing. assert ~mi(a). assert ~mi(b). gen byte c = a | b. gen byte c = a | b if ~mi(a) & ~mi(b). a|b. -- true if either a or b is true, regardless of what the other is. – 1.5.
