Working at the help desk, you receive a call and learn a user's PC IP address and mask (10.55.66.77, mask 255.255.255.0). When thinking about this using classful logic, you determine the number of network (N) subnet (S), and host(H) bits. Which of the following is true in this case?
N = 12
S = 12
H = 8
S = 8
