What is adder ? & Types of adder..



What is adder ?
Ans:-  It is a combinational logic circuit used to add two or more than two either serially and parallely..
Q):-How many  types of adder are there?
Ans:- There are two types of adder.

  1. Half adder.
  2. Full adder.
1):- What is half adder?
Ans:- It is a type of adder which is responsible to add only two bit at a time.
In half adder there are two input terminal and two output terminal  one is sum and another one is carry .

2):- What is full adder ?
Ans:- It is a type of adder which is  responsible to add three bit at a time.

In full adder there are three input terminal and two output terminal one is sum and another one is carry.

Q):-  What is logic gate ? Ans:-   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  binary  inputs and produces a single binary output.      Q):-  How many types of logic gates are there ?  Ans:-  There are three types of logic gates.   1):-     Basic gate.   2):-.   Universal gate.   3):-     Arithmetic gate./ special gate.  1):- What is Basic gate ?    And:-   These gates gives idea about one of                the fundamental expression either                  addition of variable ,                   Multiplication of variable and                     Compliment of the variable.    How many types of Basic gate are there ?  And:-   There are three types of basic gate .  a):-   NOT gate / inverter .  b):-   AND gate .  C):-   OR gate .   a):- What is NOT gate ?  Ans:- Function of  NOR  gate is to reverse  the nature  of the

What is multiplexer(MUX)? & (2:1 MUX ,4:1 MUX ,8:1 MUX )... What is multiplexer ? Ans:-  It is a combinational digital logic circuit  which consist of many input and gives output through a single common line with the help of select line. If small 'n' is the no of select line and 'N' is the no of data input line/input line.            Hence the MUX  can be named as 2:1 ,4:1 ,8 1 ,16:1........as so on. * MUX is a universal device.                    2:1  MUX nd This MUX  consist of two data input line and one data select line and switches through a single output line. Let us consider 'Io' and 'I1' is the data input line and 'So' the select line. Truth table of 2:1 MUX. Expression of 2:1 MUX. Realisation of 2:1 MUX.                            4:1 MUX This MUX consist of four data input line and two data select line and  switching through a single output line. Let us consider  Io, I1, I2
