Binary Reminder

How to count with binary numbers?

For those who don’t remember (or who don’t have any idea of) binary courses, a little reminder about binary counting is here for you!

	Operation		Result
Decimal	5	2	7
Binary	1 (1*2^2) 0 (0*2^1) 1 (1*2^0)	0 (0*2^2) 1 (1*2^1) 0 (0*2^0)	1 (1*2^2) 1 (1*2^1) 1 (1*2^0)

What is a logic gate?

A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logical inputs, and produces a single logical output.

AND Gate

For a AND gate, two inputs are needed to have a result egal 1.

OR Gate

For a OR gate, one or the other (or both) of the inputs are needed to have a result egal 1.

XOR Gate

For a XOR gate, one or the other of the inputs are needed to have a result egal 1 but not both of them.
