MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A logic gate is a device that acts as a building block for digital circuits. They perform basic logical functions that are fundamental to digital circuits. Most electronic devices we use today will have some form of logic gates in them.

Detailed explanation-2: -The basic digital electronic circuit that has one or more inputs and single output is known as Logic gate. Hence, the Logic gates are the building blocks of any digital system.

Detailed explanation-3: -AND GATE USING SWITCH As we know 2 input AND gate needs, 2 input device, that’s why we are using 2 button (input device). And we need an output device that is LED. We connect buttons in series for AND Gate. So when both buttons are not pressed it means input logic is “0 and 0”, In that case LED will not glow.

Detailed explanation-4: -Logic gates are what we use to create digital logic circuits. They’re the building blocks of computers and other electronics .

Detailed explanation-5: -The gate switches the “output” of a “decision” based on the type of gate and the information provided to the gates “input”. they are called logic gates because they operate according to Boolean logic using two states of 0 and 1.
