WHAT IS IT?

This model depicts error detection using two dimensional parity.

HOW IT WORKS

First bits are either randomly generated or taken from the user. they are then arranged in rows. Next the vertical paroty is taken out followed by the horizontal parity. now there is an extra bit that has formed. the earlier bit with their paroties at the end plus the new bit with parity is final encoded bit to be transmitted.

HOW TO USE IT

First press the startup button followed by the user_input button or the random generation button n finally the go button to get the final results.

THINGS TO NOTICE

notice that when the horizontal parity is being calculated ..it is the one bit errors in that bit that is being calculated, so the model gives both one bit n two bit parities. Also the new thing in themodel to be observed is the quiz part that has been added. its pictographic quiz. has two different questions one of which is randomly generated.

THINGS TO TRY

try the new quiz feature. also try to increase the no of bits n bytes in each bit.
