Boolean Operations
The OR operation
The OR operation is based on compound statements of the formP OR Qwhere, again, P represents one statement and Q represents another. Such state-ments are true when at least one of their components is true
The XOR operation
-
For example, a statement of the form P XOR Q means “either P or Q but not both.” (In short, the XOR operation produces an output of 1 when its inputs are different.)
The AND operation
The Boolean operation AND is designed to reflect the truth or falseness of a statement formed by combining two smaller, or simpler, statements with the conjunction and. Such statements have the generic form
where P represents one statement, and Q represents another.Ex: Kermit is a frog AND Miss Piggy is an actress.
bit 0 represents the value false and the bit 1 represents the value true. Operations that manipulate true/false values are called Boolean operations
Gates and FlipFlops

FlipFlops
A flipflops is a fundamental unit of computer memory. It is a circuit that produces an out-put value of 0 or 1, which remains constant until a pulse (a temporary change to a 1 that returns to 0) from another circuit causes it to shift to the other value.
