What is computer logic gates?

Answer 1

Logic gates are transistor circuits, normally arranged on a silicon base and encapsulated inside an integrated circuit. (chip).

Using several transistors wired together, their inputs can be arranged such that, for given inputs, the output will only change state for certain conditions.

The transistor switches are in either of two states, 'on' and 'off'. These are logic states 1 & 0 (one or zero), hence binary.

The logic uses Boolean algebra.

NOT, means it is 'not on', = OFF. This is abbreviated in the descriptions as the letter 'N'

A simple AND gate, means that the output is at level zero until both inputs have a level 1 voltage on them.

A NAND gate is a 'Not And' gate. The result is reversed. The output is always at logic level 1 until both inputs also have a level 1 also.

Answer 2

OR,AND and NOT . . .these are all the basic logic gates.............

OR gate performs simple addition operation.

AND performs simple multiplication operation.

And finally the NOT gate performs the complimentoperation. And know in advance . . NAND and NOR are called as UNIVERSAL gates!

Answer 3

It is just a logic of manipulating binary values.

Answer 4

And,Or,not
