While transmission of data, due to certain reasons data is lost or data transmitted generates errors and incorrect data reaches the destination.To detect these errors error detection codes are used.As the errors are detected error correction codes are used to remove the errors, so that the receiver gets the correct data(as far as possible).At times, it is errors don't get removed as there are certain flaws in these codes. The process is done with the help of information transmitted alongwith the data from the source.When the destination receivec the data the additional information is used to detect the error and also to correct it.Various codes like CRC,Parity check, hamming's code,golay's code etc are available for this purpose.
Basically a brief introduction to the codes with detailed description of hamming and golay's code will be covered during the seminar.The flaws in these codes will be highlighted during the seminar.
