Boolean Logic (Ch3) (M2) Flashcards
What does a logic gate do?
A logic gate is used to change bits and perform calculations within a computer
What are logic gates created by?
Logic gates are created by using transistors
What are the three basic logic gates?
The three basic logic gates are: AND, OR, NOT
What are transistors?
Transistors are tiny switches that can either be turned on or off
What are logical operators used to represent?
Logical operators are symbols used to represent circuits of transistors within a computer.
What output will a NOT logical operator produce?
A NOT logical operator will produce an output which is the opposite of the input.
What output will a AND logical operator produce?
An AND logical operator will output 1 only if both inputs are also 1.
What output will an OR logical operator produce?
An OR logical operator will output 1 if either input is 1.
What does BNAO stand for?
BNAO:
Brackets, NOT, AND, OR
If there are 3 inputs in a truth table, how many rows will there be?
3 inputs
3^2 = 9
There will be 9 rows
What is a logic circuit?
A logic circuit is just multiple logic gates put together.
What is binary the representation of?
Binary is the representation of the ‘presence’ of electricity
What does the CPU do?
The Central Processing Unit (CPU) of a computer performs calculations by using transistors acting as switches
What is a system containing two states called?
A system containing two states is called a binary system
A computer can only understand instructions in what?
A computer can only understand instructions in binary
