Computer Logic Gates and Functions

What is the common function of transistors in a computer?

• Units that store data

• Very small light switches

• Components that process information

• Building blocks of computer circuits

How do computer scientists represent a switch that is turned on?

• With the number 0

• With the number 1

• With a letter

• With a symbol

What is a 'bit' in the context of computer information?

• A unit of information, either a 0 or a 1

• A type of transistor

• A complex calculation

• A computer program

What is the function of a NOT gate?

• It combines two inputs

• It outputs a 1 if both inputs are 1

• It inverts a single input

• It outputs a 1 if at least one input is 1

When does an AND gate output a 1?

• When both inputs are 0

• When only one input is 1

• When both inputs are 1

• When at least one input is 0

What is the output of an OR gate if input A is 0 and input B is 1?

• 0

• 1

• Undefined

• Error

Which logic gate is equivalent to an AND gate followed by a NOT gate?

• OR gate

• NOR gate

• XOR gate

• NAND gate

What is the characteristic of an XOR gate's output?

• It outputs 1 if both inputs are the same

• It outputs 1 if both inputs are 0

• It outputs 1 if exactly one of its inputs is 1

• It outputs 1 if at least one input is 1
