A group of N stations share a 56-kbps pure ALOHA channel. Each station outputs a 1000-bit frame on average once every 100 sec, even if the previous one has not yet been sent (e.g., the stations can buffer outgoing frames). What is the maximum value of N?.

Consider the delay of pure ALOHA versus slotted ALOHA at low load. Which one is less? Explain your answer.
