Logic gates are basic electronic components that perform logical operations on binary inputs and produce binary outputs. There are three basic logic gates: AND, OR, and NOT. Other common logic gates include NAND, NOR, XOR, and XNOR, which are combinations of the basic gates. Logic gates are the building blocks of digital circuits and are essential components in electronic devices like computers and processors, where they manipulate binary information to perform operations and make logical decisions. They allow computers to process data using binary 1s and 0s by transforming inputs through logical functions.

3. WHAT IS LOGIC GATES?
A logic gate is a device that is 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. For example, logic gates can be used in smartphones, tablets,
or memory devices.

4. •Logic gates are the basic building blocks of
digital circuits. Theyperform Boolean
operations on input signals to produce an
output. These operations include AND, OR,and
NOT.

17. WHY DO WE NEED
LOGIC GATES?
TOPIC-2

18. Recap of Logic Gates:
Logic gates are electronic circuits with several inputs and one
output. There are three basic logic gates, namely AND gate, OR gate,
and NOT gate
• Other logic gates that are derived from these basic gates are the
NAND gate, NOR gate, EXCLUSIVE-OR gate, and EXCLUSIVE-
NOR gate.

19. What are the different uses of Logic Gates?
1.In the digital world, logic gates are the backbone of decision-making operations and task
coordination.
2.It is an electronic description of logical reasoning and a Boolean algebra mathematical
application.
3.The organization of logic into gates and other logic blocks facilitates information
interchange and design description. It is a common notation that may be understood by
anyone who is familiar with the art. It makes it possible to assemble and transfer groups of
gates and bigger blocks of logic consistently.
4.It enables the evaluation and testing of designs for accuracy.

20. Why do we need Logic Gates?
We need Logic Gate because we send information through
computers using wires that represent 1s and 0s. Computers
need a way to manipulate those 1s and 0s so that they can
eventually do more complicated operations like calculating
the 50th digit. Computers use logic gates to transform the 1s
and 0s from input wires.
