binary addition of two bits is called a half adder ,and of three bits is called a full adder to be more lucid in my explanation a half adder doesnot consider a carry generated from the previous added pair of binary numbers
consider an example :-
A=a1a2a3a4 + B=b1b2b3b4 = sum=s1s2s3s4
the actual addition procedure is a4 and b4 are added first then the sum is stored in s4 and the generated carry is added with a3 and b3 and the process continues
so addition of a4 and b4 where there is no input carry is carried out by half adder and the addition of c1+a3+b3 is carried out by full adder. but practiclly the first situation a4+b4 can be considered as a4+b4+0 so all the addition can be performed by full adder it self
truth table for both half adder
A B s c

for full adder
c1 A B s c

1 1 0 0 1
1 1 1 1 1
where s and c can be viewed as the sum and carry
on solving the k-map for full adder and half adder we can obtain the fuctions of sum and carry
Two half adders are required for making A full adder.!
where is full adder used

ans: 2048 bcz, N=256therefore, adders= N*log2N=2048

Lack of electricity is called load shedding.There are many causes of load shedding some are: 1.demandz of electricity supplier's. 2.govt irresponsibility they are not paid full payment to electricity suppliers SOLUTION: We have to make some plains and arrange meeting and make sure them that we paid your payment in installments.
AnswerA half-wave rectifier converts an alternating voltage (such as your wall socket) into a pulsing DC signal. This can be further processed with circuits called 'filters' and 'regulators' to produce a steady DC voltage (such as a battery.) The basic half-wave rectifier is a 'diode'. This is an electrical one-way street that only allows flow in one direction. When the AC voltage is going one direction, the diode allows current flow. When the AC is of the opposite direction, the diode blocks current flow. Since only one half of the full AC signal is allowed to pass, it is called a half-wave rectifier. Using 2 diodes and a center tapped transformer, or 4 diodes arranged in a bridge rectifier circuit, the entire wave can be converted and it is called a full-wave rectifier. Try researching 'power supplies' for more information.
m full adder
A full adder takes two inputs plus carry in and produces one output plus carry out. You need four full adders to add two 4 bit words. (No half adders required.)Or: for the lowest bit you can use a half-adder (no input carry).

It depends if you want your cup to be half-full or half-empty. half-full is 2 half cups half-empty is 2 empty cups
