MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A logic gate is an idealized or physical device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output.

Detailed explanation-2: -In electronics, 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.

Detailed explanation-3: -These are important digital devices that are mainly based on the Boolean function. Logic gates are used to carry out logical operations on single or multiple binary inputs and give one binary output. In simple terms, logic gates are the electronic circuits in a digital system.

Detailed explanation-4: -Any Boolean function can be implemented using only AND and INVERT gates since the OR function can be generated by a combination of these two gates, as shown in Figure 2.20(a). It follows that these two gates can implement any arbitrary Boolean function and they are said to form a complete set.

Detailed explanation-5: -Implementation of Boolean functions using NAND gates NAND gate is a logical combination of AND gate and NOT gate and this can function like AND gate, OR gate and NOT gate. So, we use NAND gates to implement the Boolean function.
