Abstract:
In today world use high speed computers.
Communication between one computer and another or
between the computer and its peripheral devices must be
as error free as possible. However, error free data
transmission in real world communication systems does
not exist. Errors, no matter how few, will always be
present. To deal with this problem, a good number of
error detection techniques have been developed and used
extensively in data communication systems known as the
Cyclic Redundancy Check (CRC). In order to
investigate the CRC error, handshake data (polynomial
and handshake data bit) is sent to receiver subsequently,
when the receiver accept the handshake, the polynomial
is accepted by receiver. While in data communication
between sender and receiver, sender packed the data and
polynomial and then transmitted to receiver. When the
packet arrived to receiver, the received packet is divided
by polynomial. The receiver catches the result data.
