What do you understand by The Hidden Node Problem? Describe 2 different spatial configurations which exemplify this issue. What is the 4B/5B encoding for the 3-byte (ASCII) string “Sun”? What is the 16-bit internet checksum for the 3-byte binary message 00110001 00110010 00110011? Suppose a message is 11011000.
