hope be sure 100% before send the answer, it's very important assighment

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=16bit 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
