3. AIM AND OBJECTIVE
 we should identify the proper IC and its pin number.
 we should design the layout and install the IC on PCB.
 we should test the output from different input
 We should correct correction of errors and should
operation safely

4. INTRODUCTION
 Error is a condition when the output information does not
match with the input information.
 During transmission, digital signals suffer from noise
that can introduce errors in the binary bits travelling from
one system to other.
 That means a 0 bit may change to 1 or a 1 bit may change
to 0.

 Error detection is the process of detecting the errors that
are present in the data transmitted from transmitter to
receiver, in a communication system.
 We use some redundancy codes to detect these errors,
by adding to the data while it is transmitted from source
(transmitter).
 There are three process of error detection
 CRC
 Parity Checking
 Checksum Error Detection

10. APPLICATION
1) The ALU (arithmetic logic circuitry) of a
computer uses half adder to compute
the binary addition operation on two bits.
2) Half adder is used to make full adder as
a full adder requires 3 inputs, the third
input being an input carry i.e. we will be
able to cascade the carry bit from
one adder to the other.
