Here is the questions in details
1. Develop a single-bit error-correcting Hamming code for 32-bit data string of your name’s first four alphabets in capital with respect to ASCII codes and then conversion it into binary in 8 bits with all necessary steps and also verify at the receiver.
2. Given the pattern of your name’s first two alphabets in small with respect to ASCII codes and then conversion it into binary in 8 bits and then encode the data using ASK, OOK, FSK, 8PSK and BPSK.
3. For the bit stream of your name’s first two alphabets in capital with respect to ASCII codes and then conversion it into binary in 8 bits, sketch the clear and scaled waveforms for each of the following codecs:-
NRZI, RZ, Pseudoternary, Manchester, Differential Manchester.

i need answer plz help me
Construct a client server model that have 9 hosts, three of them are computers, and other six hosts will be laptops, in which further connected to 2 access points through wireless channel, as three of them will be connected to access point 1 and other through access point 2, assign them IP address and subnet masks dynamically from the server. Moreover, access the HTTP server from the client and show the results.
