Assignment brief 
Many encoding schemes known in data commination, some of which are used in Ethernet network, bits are representation of data are to be encoded, explain with the aid of diagrams different modulation and encoding schemes by which data are to be encapsulated.

Data are not immune from errors during transmission, yet one of most important strategy in data communication is to communicate error-free, hence you are to discuss and show using examples different types (at least two methods) of error discovery and error correction. 
 
ARP is known to be one of important protocol used in network management, the process of this protocol can be monitored using protocol analyser, using Wireshark trace the process of ARP. Show the full work of your experiment in a logical structure.
