Science Quiz | What computers need to compute: Logic gates
Q: A logic gate is a device that performs a logical operation on the inputs it receives. E.g., the value of 1 OR 0 is 1 and the value of 1 AND 0 is 0. Name the branch of algebra that deals with such combinations and their underlying theory.
A: Boolean algebra
Q: Very large scale integration, or VLSI, refers to the technology by which billions of metal-oxide semiconductor transistors are combined in a single chip. Name the two logic gates most commonly used in these setups.
A: XOR and AND
Q: Name the two logic gates that are deemed to be functionally complete – i.e. each capable of recreating the functions of any other logic gate (AND, OR, NOT, NAND, NOR, XOR, and XNOR) by being combined in different ways.
A: NOR and NAND
Q: The most common type of transistor in modern digital circuits is the MOS. ‘MOS’ stands for metal-oxide semiconductor. What does ‘FET’ stand for?
