Q1. What is parity? Using simple parity check (even parity) how can we detect single bit error? Q2. With an example show how 2-dimentional parity check can detect 2 bit and 3 bit error. Q3. Explain CRC encoder and decoder with the help of example. Q4. With K=2 and M=16 bit use checksum technique to generate checksum for the following stream of data [10011001111000100010010010000100]. Q5.What is hamming Code and show with an example how this technique is used to detect errors
