2. Logic gates

Logic gates serve to realize different operations of Boolean algebra. To put it more simply, they implement different logical operations that are performed on one or more logical inputs and result in one logical output. The fact that Boolean algebra deals with truth, which, like our bit, can also be expressed binary, is not a coincidence. Recall that we considered conductivity as 1, which in this context can be considered true. Follows that the non-conductivity is 0 or a lie and we are back to the binary representation of one bit. In the last chapter, we were introduced to the transistor that allowed us to control that bit. In this chapter, we will use the transistors to build logic gates.
