What is IC no of NOR gate?

Answer 1

Short answer:

An IC is a "Integrated Chip".

An OrGate is a 2 (or more) input chip with onlt 1 output.

Longer answer: IC stands for Integrated Circuit, we call them "Chips" and they have multiple electronic devices integrated into them like resistors, transistors, capacitors, all in one package to make monolithic circuit package, to form everything from AndGates, OrGates, NorGates, ExOrGates, Buffers, to microprocessors and more.

an Or Gate is a digital divice with two or more INPUTS that will produce a digital OUTPUT depending on the input, if one OR the other inputs have an inupt of 1 the output will be 1 otherwise it will be 0. they are used to make "logic" and "arithmetic circuits" from calculators to computers to network cards and routers and much more.
