What gate does this symbol "¬" in the expression "¬A" represent? - NOT, Why is binary used in a computer? - It is used because computers contain billions of devices called transistors, they are either on or off, i.e. they have two states just like binary!, What gate does this symbol " v " in the expression "A v B" represent? - OR, What do we call the tables that represent all the possible inputs to a logic circuit? - Truth tables, If you have NOT(A AND B) and the inputs A=1 and B=1 what will the output be? - Logic 0, What gate does this symbol "¬" in the expression "¬A" represent? - NOT, If you have A AND (A OR B) and the inputs A=1 and B=0 what will the output be? - Logic 1, If a logic circuit has 3 inputs how many unique codes are there? - 8, If a logic circuit has 5 inputs how many unique codes are there? - 32, What is 10 MOD 4 ? - 2, What is 2 EXP 4 ? - 16, What is 43 DIV 4 ? - 10, What is 12/4 ? - 3, What is 2*(12+8-3) ? - 34, What circuit does this expression implement: ? - ¬ ( A ^ B ) ....... NOT(A AND B), What circuit does this expression implement: ? - ¬A ^ B ........NOT A AND B, What circuit does this expression implement:? - ¬A v B ....... NOT A OR B,
